Land, Zoning & Supply

01 The Planning Hierarchy

Ireland operates a top-down, hierarchical spatial planning system. Each lower tier must be consistent with the tier above it. This “plan-led” system determines where and how land can be zoned for housing.

The five tiers

Consistency requirements

The hierarchical requirement is a legal obligation under the Planning and Development Act 2000 (as amended) and reinforced by the 2024 Act. Development plans must be consistent with the RSES, which must be consistent with the NPF. Where a local authority adopts a plan that materially contravenes the hierarchy, the Office of the Planning Regulator can recommend that the Minister issue a direction to amend or revoke the offending provisions.

NPF population targets

The 25/25/50 split (Dublin / four cities / rest of Ireland) directly determines how much land each local authority must zone. The revised NPF, approved by the Oireachtas in April 2025, reflects ESRI modelling projecting a population of 6.1–6.3 million by 2040.

02 The Development Plan System

What is a development plan?

Every planning authority (31 city/county councils) must make a development plan for its functional area. The plan is the primary legal document that sets out the planning authority’s policies and objectives for the proper planning and sustainable development of the area. It includes the all-important zoning map, designating what land can be used for what purpose.

The plan cycle

Development plans previously had a 6-year lifespan. Under the Planning and Development Act 2024, this has been extended to 10 years, with a mandatory interim review after 5 years. The plan-making process takes 2+ years, involving multiple stages of public consultation and environmental assessment.

Core strategy requirement (post-2010)

Introduced by the Planning and Development (Amendment) Act 2010, the core strategy is a mandatory evidence-based justification for all residential zoning. It links the quantum of residentially-zoned land to population projections derived from the NPF and RSES. This effectively ended the pre-2008 practice of ad hoc, politically-motivated rezoning that inflated zoning far beyond any reasonable assessment of demand.

The core strategy must demonstrate that the amount of land zoned for residential use is justified by reference to population projections, and that the land is appropriately located (sequential development, compact growth) and capable of being serviced.

What a development plan contains

• Core strategy — evidence base linking zoning to population targets
• Zoning map — designation of all land by permitted use (residential, commercial, industrial, open space, etc.)
• Written statement — policies and objectives covering housing, transport, community facilities, heritage, environment, climate action
• Development management standards — density, height, plot ratio, site coverage, parking, open space, building lines
• Record of Protected Structures
• Environmental assessments — Strategic Environmental Assessment (SEA), Appropriate Assessment (AA)
• Housing strategy — assessment of housing need, including social and affordable housing (Part V)

Development management standards and their cost impact

Development plans impose detailed standards that cumulatively reduce yield per site, increase land cost per unit, and add construction costs:

The RIAI’s Low-Rise Medium-Density (LRMD) model proposes 35–80 dwellings/ha through more flexible standards, suggesting significant efficiency gains are achievable within reasonable quality requirements.

Public consultation

The plan-making process includes multiple mandatory stages of public consultation: at the pre-draft strategic issues phase, the draft plan stage, and the proposed amendments stage. Any person may make a submission, and the planning authority must consider all submissions received. However, the final decision on the content of the plan — including zoning — rests with the elected members (councillors), not with the professional planning staff.

The role of elected members

Councillors have the legal power to make zoning decisions, which is a democratic feature of the system. The Chief Executive (formerly City/County Manager) recommends a draft plan, but councillors can amend it by majority vote, including amending the zoning map. This power has historically been abused — as exposed by the Mahon Tribunal — but remains a fundamental feature of local democratic control over planning.

Material contravention — Section 34(6)

A “material contravention” allows development that is inconsistent with the development plan, subject to strict procedures. At the local authority level, a grant of permission that would materially contravene the plan requires a resolution of not less than three-quarters of the members of the planning authority. At Board level (An Coimisiún Pleanála), material contraventions can be permitted on specific grounds including compliance with national policy, housing need, or sustainable development objectives.

Common grounds include height, density, parking, and unit mix. The SHD (Strategic Housing Development) process (2017–2022) saw widespread use of material contraventions, but many permissions were judicially reviewed and quashed. Material contraventions are a necessary safety valve but create uncertainty and legal risk.

Mid-cycle changes (variations)

A variation allows amendments to the development plan between review cycles. The process takes a minimum of 4–6 months and requires public consultation, SEA/AA screening, and a vote of elected members. Variations are the primary mechanism for mid-cycle rezoning but are constrained by the core strategy requirement. In July 2025, the Minister for Housing issued guidelines directing all local authorities to reopen their development plans via variation and zone additional residential land with 50% headroom above baseline requirements.

03 Zoning: How It Works

What is zoning?

Zoning is the process by which land is designated for particular uses in a development plan. Each parcel of land in a local authority area is assigned a zoning category that determines what types of development are permitted, open for consideration, or not permitted.

Common zoning categories

The legal effect of zoning

Zoning is a binding constraint: housing can generally only be built on land zoned for residential or residential-inclusive mixed use. An application for housing on land zoned for industrial or agricultural use will normally be refused. However, there is a critical distinction in the Irish system:

The discretionary system

Ireland is the only country in the developed world with both American-style zoning and British-style discretionary assessment. In Germany, France, the Netherlands, and Japan, compliance with the zoning plan gives a developer a legal right to build. In Ireland, every planning application is assessed on its merits by planners who exercise significant discretion, even where the proposed development is consistent with zoning. Grounds for refusal can include impact on amenity, design quality, traffic, drainage, overlooking, and many other considerations.

This hybrid system has been described as “no longer fit for purpose” and a “key contributory factor to the growing housing emergency.”

Sequential development

Development plans apply a sequential approach to zoning: brownfield/infill sites are prioritised, followed by inner suburban, then outer suburban, and finally edge-of-settlement lands. This reinforces the NPF’s compact growth target (40% of new housing within existing built-up areas) but means some zoned land on the urban edge may not be “activated” during the plan period, reducing effective supply.

Strategic land reserves

Some land is zoned as “strategic residential reserve” (R4/SRR) — designated for future development but not available for housing during the current plan period. This land appears in the total quantum of residentially-zoned land but cannot contribute to immediate supply. Similarly, greenbelt zoning prevents urban sprawl but removes land from potential supply.

04 Rezoning: Politics, Corruption & Reform

Three routes for rezoning

Rezoning decisions are made by elected councillors, not planning officials. This democratic feature has both strengths (local accountability) and weaknesses (vulnerability to political influence and corruption).

The Mahon Tribunal

The Tribunal of Inquiry into Certain Planning Matters and Payments (the Mahon Tribunal, 1997–2012) exposed systemic corruption in the rezoning process, particularly during the Celtic Tiger era. The Tribunal found evidence of councillors receiving payments in exchange for rezoning votes, land speculators profiting from inside knowledge of rezoning decisions, and a culture of “brown envelope” payments to political figures.

Key Mahon Tribunal outcomes:

• Exposed corruption in Dublin County Council rezoning decisions in the 1990s
• Recommended the establishment of the Office of the Planning Regulator (OPR) to independently oversee planning decisions
• Led to the Lobbying Act 2015, requiring registration of lobbying activities
• Prompted reforms to strengthen the evidence-based approach to zoning (core strategy requirement)
• Created a lasting stigma around rezoning, contributing to a post-crash culture of extreme caution

Post-Mahon reforms

The OPR (established 2019), the core strategy requirement (2010), and the NPF hierarchy have collectively transformed the rezoning process from one driven by local political interests to one constrained by evidence, national targets, and independent oversight. However, tensions remain between local democratic control and national planning discipline, as illustrated by cases like Clare County Council’s excessive zoning (2023) and Kildare Town’s de-zoning of serviced land.

05 The Zoning Premium

The act of rezoning land from agricultural to residential use creates an enormous uplift in value. The CSO publishes data on both agricultural and residential land prices, making it possible to quantify the zoning premium precisely.

CSO data (2024)

The thin market problem

The CSO’s residential land price data is based on a very thin market: only 767 acres of residential development land were traded nationally in 2024. Small sample sizes mean that median prices can fluctuate significantly year-to-year, and individual large transactions can distort the figures. Nevertheless, the broad pattern — a 20–30× zoning premium — is consistent across multiple data sources and years.

What the premium means

The zoning premium represents the capitalised value of the planning permission that zoning makes possible. It is created entirely by a public decision (the zoning vote) but captured almost entirely by the landowner. This is the “unearned increment” that has been debated in Irish public policy since the Kenny Report of 1973. The Land Value Sharing mechanism (25% charge on the rezoning uplift, as enacted in the Planning and Development Act 2024), combined with development levies and Part V, aims to recover some of this premium for the community.

06 Residential Zoned Land Tax (RZLT)

What is it?

The RZLT is an annual tax on land that is zoned for residential or mixed-use (including residential) purposes, is serviced (or capable of being serviced), and is not yet developed for housing. It was introduced by the Finance Act 2021 as Part 22A of the Taxes Consolidation Act 1997, as part of the Government’s Housing for All plan (September 2021).

Rate and who pays

Rate: 3% of the market value of the land, charged annually on a self-assessment basis. The landowner self-assesses the market value, subject to Revenue audit.

Who pays: The owner of the land as at 1 February of each year — individuals, companies, trusts, or any other entity holding ownership of qualifying land.

What land is included

Land appearing on local authority RZLT maps that meets all of the following criteria:

1. Zoned for residential or mixed use (including residential) in a development plan or local area plan
2. Serviced (or capable of being serviced): access to public road, water supply, and foul sewer drainage
3. Not excluded from the tax (existing homes subject to LPT, land integral to a business, infrastructure land, derelict sites)
4. Not already in residential use

The mapping process

The RZLT operates through a mapping system administered by the 31 local authorities:

The amount of land on the maps reduced significantly through submissions and appeals. Initial estimates of ~52,000 hectares were reduced to approximately 6,500 hectares of zoned and serviced land on the final maps — a dramatic narrowing of scope.

First-year results

Exemptions and deferrals

• Existing residential properties: Land subject to LPT is generally exempt (but large gardens >0.4047 ha / 1 acre may require registration)
• Active development (deferral): Where residential development has commenced, RZLT can be deferred. Over 500 returns in year one claimed deferral.
• Planning appeal pending: Finance Act 2024 upgraded this from a deferral to a full exemption during third-party judicial review.
• Rezoning request: Landowners can request rezoning annually (April deadline) to reflect genuine economic use. Exemption applies during the process.
• Farmland: No blanket farmland exemption. Farmers must apply annually to rezone their land — described by the IFA as “only a year-by-year solution.”

The farmer’s dilemma

Comparison with the Vacant Site Levy

The fundamental design improvement is the shift to Revenue collection. Revenue has far greater enforcement powers than local authority planning departments: ability to attach bank accounts, interest and penalties on late payment, integration with existing taxpayer records, and established audit capacity. The VSL’s 1.37% collection rate versus the RZLT’s €46 million first-year collection demonstrates the difference.

Criticism and legal challenges

• Farmland concerns (IFA): Annual rezoning-based exemption is inadequate; farmers campaign for a permanent exemption for genuinely active farmland
• Mapping accuracy: Inconsistent criteria across local authorities; some land mapped as “capable of being serviced” faces significant infrastructure deficits in practice
• Administrative burden: Self-assessment requires market valuations; annual mapping/rezoning process creates ongoing requirements
• Legal challenges: 25 judicial review actions were brought before the High Court; 13 of 25 remained before the court as of mid-2024; common grounds include inadequate services and procedural errors

07 Land Value Sharing

The 2024 bill

The Land Value Sharing (LVS) mechanism was introduced as part of the Planning and Development Act 2024. It imposes a 25% charge on the uplift in land value arising from a zoning decision (reduced from the 30% originally proposed) — the difference between the land’s value in its previous use and its value under the new zoning.

How it works

• When land is rezoned from a lower-value use (e.g., agricultural) to residential, the uplift in value is assessed
• 25% of that uplift is payable to the local authority as a “land value sharing contribution” (reduced from the 30% in the original General Scheme)
• The charge is triggered at the point of development (when planning permission is granted and development commences), not at the point of rezoning
• Combined with development levies and Part V (20% social/affordable housing), the State could recover 50%+ of the zoning uplift

Current status

The LVS provisions are not yet fully operational. The Act was passed in 2024 with phased commencement. The detailed regulations, valuation methodology, and collection mechanisms are still being developed. The LVS represents a significant policy shift toward community capture of planning gain, building on decades of debate since the Kenny Report.

Interaction with RZLT

The RZLT and LVS are complementary but distinct. RZLT is an annual holding charge on land that is already zoned but undeveloped — it penalises inaction. LVS is a one-time charge on the value uplift from a new zoning decision — it captures a share of the windfall gain. Together, they aim to ensure that landowners cannot capture the full benefit of public planning decisions without contributing to the community.

08 The Kenny Report (1973)

What it recommended

The Committee on the Price of Building Land, chaired by Mr Justice John Kenny, reported in 1973. Its central recommendation was that local authorities should be empowered to compulsorily purchase (CPO) development land at its existing use value (EUV) plus 25% — rather than at its full development (zoned) value. This would have prevented landowners from capturing the full windfall of zoning decisions, keeping land costs dramatically lower for housing.

Why it was never implemented

The Kenny Report was shelved for over 50 years despite repeated calls for its implementation. The political and legal obstacles included:

• Property rights: Article 43 of the Constitution guarantees the right to private property. Successive governments feared that CPO at below-market value would be struck down as unconstitutional.
• Political opposition: Landowners, developers, and the construction lobby opposed any measure that would reduce land values or profits from rezoning.
• Lack of political will: During the Celtic Tiger boom, rising land values were seen as wealth creation rather than a problem. After the crash, the focus was on recovery rather than structural reform.

Constitutional status

The constitutionality of Kenny-style compulsory acquisition has been debated but never definitively resolved by the Supreme Court. Legal commentators and the Housing Commission (2024) have noted that Article 43.2 of the Constitution explicitly permits the State to delimit property rights "with a view to reconciling their exercise with the exigencies of the common good," and that a severe housing crisis could provide sufficient justification for legislation permitting CPO at existing use value plus a premium. However, no Supreme Court judgment has squarely endorsed the Kenny recommendations. C3

What it would mean today

If the Kenny Report’s recommendations were implemented today, using the CSO’s 2024 data:

A Kenny-style CPO would reduce land costs by approximately 95%. On a typical 3-bed semi site in Dublin (0.05 acres per unit at suburban density), this would reduce the land cost per unit from approximately €32,000 to approximately €1,500 — a saving of €30,000+ per home. Over 50,000 homes per year, the aggregate saving would be in the billions.

The Land Value Sharing mechanism (25% charge) represents a partial step toward the Kenny Report’s vision, but captures far less of the uplift than Kenny’s EUV + 25% would.

09 Land Supply: The Numbers

How much land is zoned?

Ireland has approximately 75,000 hectares of residentially-zoned land, plus ~21,000 hectares of mixed-use land that includes a residential component. However, the gap between “zoned” and “development-ready” is vast. When the RZLT mapping process filtered for land that is both zoned and serviced, only approximately 6,500 hectares remained on the final maps — roughly 7% of the total residentially-zoned quantum.

Why most zoned land isn’t developed

• Infrastructure deficits: Water, wastewater, and electricity capacity constraints prevent development on much zoned land
• Land banking: Owners hold land for future sale or development, waiting for higher values
• Sequential development: Outer sites are deprioritised in favour of brownfield/infill
• Strategic reserves: R4/SRR zoned land is not available in the current plan period
• Locational mismatch: Some zoned land is in areas with insufficient demand to support viable development
• Fragmented ownership: Assembly of multiple parcels into development-ready sites is time-consuming

Activation rate

Only approximately one-sixth (~17%) of residentially-zoned land is activated for housing during a plan period. This means that in any given 6–10 year cycle, the vast majority of zoned land does not produce housing.

Dublin: the supply paradox

The four Dublin local authorities have approximately 2,233 hectares zoned for up to 100,000 homes. Yet actual completions in Dublin in 2024 were only 3,355. In July 2025, the Minister directed Dublin City Council to double its zoning target to 12,294 homes per year — but this remains nearly four times actual delivery.

The 39,000 uncommenced permissions

As of recent data, approximately 39,000 apartment permissions in the Dublin area remain uncommenced. These permissions represent housing that has been approved by the planning system but not built — typically because the development is not financially viable at current construction costs, because of infrastructure constraints, or because the permission holder is waiting for market conditions to improve. This figure underlines that planning permission, like zoning, is a necessary but not sufficient condition for housing delivery.

The 2025 ministerial direction

In July 2025, the Minister for Housing issued guidelines directing all 31 local authorities to reopen their development plans and zone additional residential land with 50% headroom above baseline requirements. This means zoning capacity for approximately 83,000 homes per year nationally — well above even the revised target of 55,000. The 50% headroom acknowledges the reality that not all zoned land will be activated and builds in a buffer for the gap between zoning capacity and actual delivery.

10 The Office of the Planning Regulator (OPR)

Establishment and role

The OPR was established in 2019, a direct outcome of the Mahon Tribunal’s recommendations. It is an independent body tasked with overseeing the planning system and ensuring that development plans and local area plans are consistent with national and regional policy.

Key functions

• Assessment of development plans and LAPs at draft and amendment stages — the OPR reviews every plan and can make recommendations or observations
• Ministerial directions: Where a local authority adopts a plan that materially contravenes the planning hierarchy, the OPR can recommend that the Minister for Housing issue a formal direction to amend or revoke the offending provisions
• Review of zoning decisions by elected members, particularly where councillors override professional planning advice
• Planning research, education, and performance monitoring
• Review of planning authority performance in implementing national planning policy

Interventions

The OPR has been active since its establishment. Notable interventions include:

Flood-risk interventions

Between 2019 and 2025, the OPR intervened to prevent 288 sites at flood risk from being zoned for housing or other vulnerable development. In 30 cases where local authority councillors did not accept the OPR’s recommendations, the Minister had to issue formal directions to block the zoning. This demonstrates both the OPR’s effectiveness and the persistence of local political pressure to zone inappropriate sites.

Tension with local democracy

The OPR’s role creates an inherent tension: it overrides decisions made by democratically elected councillors in the name of national planning policy. Critics argue this undermines local democracy; supporters counter that the Mahon Tribunal demonstrated the dangers of unchecked local zoning power and that national consistency is essential in a small country with a single housing market.

11 NESC Recommendations

Report No. 145: “Urban Development Land, Housing and Infrastructure” (May 2018)

The National Economic and Social Council’s landmark report described the Irish housing system as “speculative, volatile and expensive”. It found that the urban land system was dysfunctional, with land not available in appropriate locations at a cost that allows affordable housing.

Key recommendations

Report No. 150: “Housing Policy: Actions to Deliver Change” (November 2020)

NESC called for “bold action urgently needed to fix the dysfunctional housing system” and argued Ireland must evolve from a “speculative and highly cyclical system to a permanently affordable, stable and more sustainable system.”

NESC’s systemic critique

NESC has noted that Ireland’s policy approach frequently involves “one aspect being described as the problem and one marginal action being advanced as the solution” rather than taking a system-wide approach. It has warned that “sometimes one policy initiative cancels out the effect of others.” NESC has advocated an element of active land management as far back as 2004, “but this had been ignored by the Government.”

The international models

Germany

Municipalities use detailed binding land-use plans (Bebauungspläne) that give developers legal certainty. Local government has greater resourcing for plan-making. Germany builds more houses per capita than England or Ireland.

Netherlands

Active land policy where municipalities acquire, develop, and sell serviced land. Land-use plans (bestemmingsplannen) provide legal certainty for compliant development. 15–20% of new housing comes from repurposing existing buildings.

Austria

“Active land management” is a feature of Austria’s well-performing housing sector. Municipalities play a direct role in land supply, acquiring land at pre-zoning values and servicing it before sale to developers. The ESRI specifically recommends Ireland adopt the Austrian model.

12 ESRI Research

Key finding: prices don’t drive supply in Dublin

The ESRI’s research on housing supply elasticity has produced a critical finding: higher house prices do not reliably drive increased supply in Dublin. The conventional economic assumption — that rising prices will incentivise more building — breaks down in a constrained market where planning delays, infrastructure deficits, labour shortages, and regulatory costs create binding supply bottlenecks.

Supply projections

ESRI research (2024) indicates Ireland needs 44,000 housing units per year on average to meet structural demand, rising to approximately 52,000 per year when pent-up demand is included. The revised NPF (April 2025) reflects ESRI modelling projecting a population of 6.1–6.3 million by 2040, requiring approximately 50,000 units per annum. The ESRI warned in May 2025 that there would be “no major uptick in 2025 and 2026” in housing supply.

“Soft costs” exceed hard costs

The ESRI’s paper RS175, “Contrasting Housing Supply in Ireland, Northern Ireland and the Rest of the United Kingdom” (January 2024), found that:

• “Soft costs” (regulations, standards, planning) push up costs more than differences in the price of construction products
• Ireland has the highest minimum floor space requirements for apartments in Europe
• Judicial reviews add between €10,000 and €20,000 to the cost of an individual home
• Legal challenges are holding up nearly 15,000 homes in the planning system

Specific ESRI recommendations

13 Housing Commission Recommendations

Background

The Housing Commission was established in December 2021 and reported in May 2024 with 83 recommendations and hundreds of suggested actions. Its headline finding: Ireland has an underlying housing deficit of between 212,500 and 256,000 homes. The Commission concluded that “exceptional and radical measures are required.”

Key recommendations

Proposed constitutional text

Implementation

The Government stated that 65 of 83 recommendations (78%) are “already implemented, under way or partially under way.” However, this figure includes “partially underway,” which may overstate actual implementation. An inter-departmental group was to be convened to develop further policy recommendations.

14 International Comparison

Two models of planning

European planning systems broadly fall into two categories:

Ireland vs Germany

Germany operates a two-tier local planning system: the Flächennutzungsplan (F-Plan, preparatory) and the Bebauungsplan (B-Plan, binding). B-Plans are significantly more detailed than Irish development plans — setting mandatory building lines, permitted uses, heights, densities, and setbacks. The key advantage: compliance with the B-Plan gives a legal right to build. This frontloads planning effort into plan-making, making individual approvals faster, cheaper, and more certain.

Ireland vs the Netherlands

The Netherlands uses land-use plans (bestemmingsplannen) that specify where construction may take place, what may be built, the size of structures, and permitted uses. If a proposal complies with zoning and building regulations, permission should be granted. The Dutch system also includes active land policy, with municipalities acquiring and servicing land before sale — 15–20% of new housing comes from repurposing existing buildings.

Ireland vs England

Ireland vs Denmark

Denmark operates a three-tier hierarchical system (national → municipal → local). The 2015 Planning Act allows municipalities to require up to 25% social housing in new neighbourhoods, with 40-year interest-free government loans for affordable housing. Only 8 of 98 municipalities had used this tool by 2021 (primarily Copenhagen and Aarhus).

OECD findings

• OECD Land-Use Regulation Index: Tight land-use restrictions combined with positive earnings shocks explain substantial house price increases. Simulations suggest that if highly regulated regions had less restrictive regulations, house prices would have been 25% lower.
• An Agenda for Housing Policy Reform (2024): Recommends “sufficiently flexible” land-use and spatial-planning policies, removing obstacles to densification, repurposing non-residential areas, and making vacant land available.
• EU Affordable Housing Plan (December 2025): EU needs 2+ million homes/year vs 1.6 million currently built. Identifies “stringent zoning and lengthy permitting processes and NIMBYism” as barriers.

The UK deficit

The Centre for Cities (2025) found that the UK has accumulated a shortfall of 4.3 million missing homes compared to the average Western European country since the post-WWII planning system was introduced. Germany, France, and Japan — all with zoning-based systems — build more houses than England. The recommendation: shift toward rules-based, spatial planning.

15 Case Studies

16 Other Advisory Bodies

National Competitiveness and Productivity Council (NCPC)

The NCPC finds that the housing market is “currently inhibiting the performance of Ireland’s competitiveness.” The construction sector is the only one with fewer employees today than during the Celtic Tiger era. Key recommendation: greater adoption of Modern Methods of Construction (MMC) to reduce labour demand pressure.

Irish Fiscal Advisory Council (IFAC)

IFAC found Ireland’s infrastructure is 25% lower than the average for comparable European countries. Large shortfalls exist in housing, health, transport, and electricity. IFAC estimated 68,500 homes per year need to be built to catch up — more than double recent output. Employment in construction would have to increase by almost 80,000, though productivity improvements could reduce this to <20,000. The main constraint is “not money but the lack of spare capacity in the economy.”

Competition and Consumer Protection Commission (CCPC)

Found knowledge gaps, financial pressures, and delays in conveyancing as ongoing issues. Home building issues were the second biggest call driver to the CCPC in the first half of 2025 (~1,250 contacts). Recommends a state competency register of builders (legislation passed 4+ years ago but not implemented).

Oireachtas Library & Research Service

“Capacity Constraints and Ireland’s Housing Supply” (February 2025): Financial viability is a significant problem, particularly for apartment construction, where a “considerable gap has emerged between cost of delivery and market prices.”
