The most sophisticated counter-argument to the developer margin analysis is that the 76–81% GOS/GVA figure is a mechanical consequence of the land price inflation system, and that the real windfall beneficiaries are landowners, not developers. This section engages that argument directly.
Residential zoned land trades at a dramatic premium over agricultural land in Ireland. The CSO’s RZLPA01 series is a Frontier Series Output: verification rates are higher in recent years, and cross-year volume comparisons are unreliable. With the full transaction volume data now available, a more precise assessment is possible. The 2024 figure (€642,613/acre, Dublin; €231,171/acre national) is the most reliable in the series: 41 transactions covering 25 hectares, with a moderate mean/median gap. The 2023 figure (€565,000/acre Dublin) should be treated with significant caution; it rests on only 3 hectares of transactions with a mean/median gap of 167%, indicating a handful of very high-value transactions drove the average. The 2022 spike to €920,000/acre is similarly low-volume (8 hectares). The report uses 2024 figures as the primary reference because they are the most transaction-weighted.

In Dublin in 2024, agricultural land: €24,125/acre. Residential zoned: €643,000/acre. The €618,875 differential is created entirely by a planning designation change — no improvement to the land, no investment, no labour. The 2024 national residential zoned land price of €231,171 per acre is 42% above the 2018 baseline of €162,868, confirmed by the CSO’s November 2025 release. The 2022 spike to €920,000/acre in Dublin illustrates the ceiling of the premium; even the more conservative 2024 median represents a 64:1 ratio against agricultural value.
The RZLPA01 2024 regional data confirms that the rezoning premium isn’t solely a Dublin phenomenon, though the capital represents the extreme. Residentially zoned land across all Irish regions trades at multiples of agricultural value that would be extraordinary by European standards.

Source: CSO RZLPA01 regional breakdown, 2024. Agricultural land comparison: CSO ARA02 national median €9,988/acre; Dublin ARA02 €24,125/acre. Regional agricultural prices approximate based on ARA02 national figure; exact regional agricultural prices not separately published. South-West Cork residential zoned figure directly relevant to the Marina Depot and Blackrock Villas case studies in Section 8.
The South-West (Cork) figure of €363,000/acre — on 59 transactions covering 60 hectares, the most transaction-weighted regional figure outside Dublin — is directly relevant to the Marina Depot case study. At that regional rate, the 4.59-hectare Marina Depot site carries a 2024 residential zoned land value of approximately €4.37 million per hectare, or roughly €20 million for the whole site — against the €15 million Glenveagh paid in 2018 and the ~€525 million total development value. The planning system added more value to that site between 2018 and 2024 than the entire purchase price, at Cork regional land price rates, before accounting for the full development value.
The counter-argument runs as follows: if developers must purchase land at residential zoned prices (€643k/acre in Dublin), their subsequent GOS/GVA margin is calculated on a value-added base that has already absorbed that cost. A developer buying at €643k and selling 10 units at €500k each (€5m total) generates a developer margin of roughly 20–27% of the house sale price, not 76%. The 76% GOS/GVA is ‘on a small base,’ not on the whole house price.
This argument is arithmetically correct on its own terms. GOS/GVA doesn’t measure profit as a share of house price; it measures profit as a share of the value the developer creates. If the developer’s primary activity is holding and converting land, the ‘value created’ is small relative to the final sale price, so a high GOS/GVA is consistent with a moderate margin on the total transaction.
Germany: 62.9% GOS/GVA. France: 50.6%. Netherlands: 66.4%. Ireland: 81.1%. Irish developers maintain a higher value margin than French or German developers even though those land markets are at least as expensive in absolute terms. The elevated Irish margin persists after land cost is absorbed; it can’t be explained by land cost alone.
Ireland generates €199 in F41.1 GOS per person — 4.1× the EU-27 average of €49. If the mechanism were purely land-cost pass-through, Ireland’s per-capita GOS should not systematically exceed comparable economies by this margin. The excess (approximately €765m per year) has no structural justification in EU comparative terms.
The same parent company frequently owns both the NACE 411 developer and NACE 412 builder entity. The ‘developer pays inflated land prices’ argument assumes arm’s-length parties. In many cases they aren’t: the planning uplift is captured within the group at the 411 level, and the inflated site cost is then transferred to the 412 subsidiary as an internal cost.
The most direct empirical test of the cost argument is one that is almost never applied in Irish housing policy discussions: what happens when the same construction company operates across multiple EU jurisdictions simultaneously? If Irish developer margins are elevated because of genuinely higher input costs (materials, labour, finance) then international contractors operating in Ireland and elsewhere should show elevated margins wherever they operate, because they face the same cost pressures. They don’t.
Royal BAM Group is the Netherlands-headquartered parent of BAM Ireland, one of Ireland’s largest construction contractors. Royal BAM operates in Ireland, the Netherlands, Germany, Belgium, and the United Kingdom. Its Dutch operations function in a housing market where the Eurostat NACE F41.1 GOS/GVA is 66.4% — well above the EU average but substantially below Ireland’s 81.1%. Its Irish operations function in a market generating an 81.1% developer value margin and €199 per capita in developer surplus against the Netherlands’ €83 per capita. BAM Ireland works with the same group procurement relationships, the same capital access, the same management expertise, and the same materials supply chains as BAM Netherlands. The differential in market outcomes isn’t explained by BAM’s cost base. It is explained by the institutional framework within which BAM operates in each jurisdiction — specifically, how planning permission value is distributed and whether a private developer extraction layer sits between agricultural land and completed home.
The same analysis applies to other major contractors operating across EU borders: Sisk Group (Ireland, UK, Germany), Mercury Engineering (Ireland, UK, Europe), and the large institutional developers who operate in Ireland, the Netherlands, and Germany through the same parent fund structures. These firms don’t carry their Irish margin structure into the markets where they operate elsewhere. Their margins in Denmark, Germany, and France are lower, not because they become less skilled or their costs rise, but because the planning-permission extraction layer that inflates Irish margins doesn’t exist in those markets in the same form. The margin follows the institution, not the firm.

The reductio ad absurdum of the cost-justification argument is the implicit claim that countries with lower developer margins must be building fewer or lower-quality homes — that the 81% GOS/GVA is somehow necessary for residential construction to occur at all. Denmark’s NACE F41.1 GOS/GVA is −232.7%: the developer sub-sector runs at an operating loss on this metric. Germany’s is 62.9%. France’s is 50.6%. Finland’s is 16.3%.
These aren’t countries without buildings. Denmark has some of the highest-quality residential stock in Europe, consistently builds above its household formation rate, and maintains a price-to-income multiple of approximately 4–5× against Ireland’s 6.8×. Germany builds approximately 5–6 units per 1,000 population annually. France approximately 6. Their buildings are built. Their builders are paid. Their planners are employed. Their architects design. Their electricians wire and their plumbers fit. The entire physical production chain of construction operates profitably and sustainably in countries where the NACE 411 developer extraction layer generates margins of 50–66% rather than 81%. The only thing missing in those markets is the planning-permission rent, and none of them are suffering from its absence.
The question that is never asked in Irish housing policy debate, and that this report asks directly: if Denmark can build homes of exceptional quality with a developer sub-sector running at a near-zero or negative margin, what precisely is the function of Ireland’s 81% developer margin? It isn’t purchasing materials, because materials cost the same. It isn’t paying workers, because COE data shows NACE 411 pays relatively little in wages. It isn’t financing construction, because the physical building is contracted to NACE 412. It isn’t managing risk, because the risk-adjusted returns on aircraft leasing, a sector with genuine geopolitical and asset destruction exposure — are 9.6% against the developer’s 81%. The 81% is the price of the planning permission, nothing more, and Denmark proves a housing system can do without it.
**Layer 1 — Landowner Rezoning Windfall: ** Agricultural land rezones at 18–27× its agricultural value nationally. This is real and poorly-taxed.
**Layer 2 — Developer Planning-Permission Premium: ** Even after purchasing land at inflated zoned prices, Irish developers retain 81.1% of all value created — 17 percentage points above the EU average. This is the developer layer extracting value above and beyond what land costs would mechanically produce.
Policy that addresses only Layer 1 without addressing Layer 2 will reduce the landowner windfall but leave the developer premium structurally intact.
The empirical backbone of the viability narrative is the Society of Chartered Surveyors Ireland’s ‘Real Cost of New Apartment Delivery’ series, cited across government documents, Oireachtas debates, and media coverage as proof that apartments cost more to deliver than they can be sold for. The December 2025 edition — built on a dataset of 12,077 apartments across Dublin, Cork, Limerick and Galway — deserves engagement on its own terms, because its own published breakdowns contain the answer to the question it is used to foreclose. The figures below are the SCSI’s own, from its Figure 3 itemisation of a typical new two-bedroom apartment (Category 2, lower range, medium-rise suburban Dublin).
| Cost Component (SCSI Figure 3) | Amount per unit | Share of total | What it actually is |
|---|---|---|---|
| Construction (hard costs) | €284,000 | 51% | Building the building |
| Site purchase | €50,000 | 9% | The land — at post-uplift market price |
| Development finance | €31,000 | 6% | The cost of carrying the land and build |
| Margin/risk (15% hurdle) | €64,710 | 12% | The developer’s required profit — inside the ‘cost’ |
| VAT on sales | €57,093 | 10% | Tax — partially reversed by Budget 2026 |
| Professional fees | €24,000 | 4% | Genuine delivery cost |
| Contributions (levies) | €20,400 | 4% | Genuine delivery cost |
| Selling costs | €12,000 | 2% | Marketing and sales |
| Contingency | €10,000 | 2% | Genuine delivery cost |
Source: SCSI, ‘The Real Costs of New Apartment Delivery 2025’, December 2025, Figure 3 (Category 2 lower range, two-bedroom, including VAT on sales at 13.5%). Dataset: 12,077 apartments, normalised to Q2 2025 baseline. The report’s executive summary chart presents the same stack at the 9% VAT rate, totalling €541,000.
The SCSI’s own report states that hard costs average 50% of overall development cost across its categories (up from 47% in 2021). The other half isn’t bricks and labour. Reading the SCSI’s own itemisation: the site purchase (€50,000, the post-uplift market price of the land, i.e. the planning rent), development finance (€31,000 — substantially the cost of carrying that land), the required margin (€64,710, the developer’s profit, booked as a cost line), and VAT (€57,093, a tax transfer, now partially reversed) together amount to approximately €203,000, or 37% of the all-in figure. When a developer states that an apartment ‘costs’ €540,000 to deliver, more than a third of that figure is the price of the planning permission, the interest paid while holding it, the profit demanded on top, and the tax on the sale — none of which is a resource cost of constructing anything. (The finance line also bounds the financing-cost objection examined in the European-comparison post: on the industry’s own figures, the lenders’ take per unit is roughly half the developer margin, and the viability hurdle is computed after the lenders are paid.)
The viability methodology compounds the framing. The SCSI assesses a project as ‘financially viable’ only if it clears a minimum profit/risk hurdle of 15%. A project earning a 14% margin is classified as financially unviable. The December 2025 report’s own pre-intervention findings make the consequence explicit: the higher cost range of Category 4 earned a positive 8% gross margin (a profitable scheme) and was ‘deemed financially unviable’ under the hurdle. The ‘viability gap’ that Croí Cónaithe exists to bridge with public money is therefore not, in the industry’s own methodology, the gap between cost and revenue. It is the gap between the developer’s actual profit and the developer’s required profit. For the most part the state isn’t rescuing loss-making schemes; it’s topping up sub-hurdle returns to the 15% threshold, and beyond it.
The ‘beyond it’ is documented in the same report. Before the Budget 2026 interventions, the lower cost ranges of Category 3 and Category 4 were already viable on the SCSI’s own hurdle, at +16% and +18% gross margin respectively. After the VAT reduction, those margins rose to +22% and +24%. The state intervention wasn’t confined to bridging gaps; because the VAT cut applies to all qualifying sales, it raised margins on schemes that had no gap — converting an 18% return into a 24% return at public expense. The SCSI’s case study quantifies the per-unit effect on the build-to-sell tenure: a baseline loss of €24,000 per unit became a €62,000 surplus after the VAT reduction and Croí Cónaithe support, an €86,000 per-unit swing delivered by state measures.
And then there is the December 2025 report’s own headline, printed in capitals on its executive summary: targeted Government interventions ‘HAVE SUCCEEDED IN ADDRESSING THE FINANCIAL VIABILITY GAP.’ The industry’s own professional body, in its own flagship cost study, declares the viability gap closed. Two observations follow. First, if the gap is closed, the rationale for the subsidy architecture has expired on the industry’s own evidence — yet no sunset of the VAT reduction or Croí Cónaithe has been proposed; the lobbying documented in Section 7.3 runs in exactly the opposite direction. Second, the same report finds that affordability hasn’t been fixed: a first-time buyer couple requires a minimum salary of between €108,000 and €146,000 to purchase the two-bedroom apartment whose viability the state has repaired, and the Help-to-Buy and First Home schemes are largely unavailable above the €500,000 price threshold that most of the analysed categories exceed. The state’s interventions, on the industry’s own December 2025 numbers, have restored the developer’s margin and left the buyer’s problem intact. That outcome is what the policy architecture documented throughout this report is built to produce.

When lobby groups present project-level viability spreadsheets demonstrating that a development can’t break even without record-high sales prices, they exploit a deliberate accounting blind spot created by vertical integration. In modern Irish real estate delivery, the Developer (NACE 411) and the Builder (NACE 412) are frequently separate corporate arms of the same parent holding company. This section documents that structure using publicly available corporate records.
PARENT HOLDING COMPANY
COMPANY A — Developer (NACE 411) — 81.1% GOS/GVA
COMPANY B — Builder (NACE 412) — 39.8% GOS/GVA (2022)
Company A acquires land, captures rezoning uplift, transfers site to Company B at inflated price.
Through internal transfer pricing, the parent company extracts a large, lightly-taxed capital profit at the Company A level before a single physical resource is deployed. Company B is handed a site heavily burdened with internal debt. When Company B claims to be struggling under tight margins, it is a manufactured corporate artifact. The project is ‘unviable’ only because the parent company chose to capture its multi-million euro profit at the planning phase rather than the construction phase.
The Eurostat data makes this structure legible in the numbers. Ireland’s F41.1 GOS/GVA (81.1%) and F41.2 GOS/GVA (39.8%) diverge by 41 percentage points in 2022. In Germany the equivalent gap is 62.9% vs 30.5% (32 points. In France it is 50.6% vs 13.5%) 37 points. Ireland’s 47-point F41.1/F41.2 spread is among the widest in the EU, consistent with a system in which value is deliberately concentrated at the development layer before the physical production layer commences. The planning uplift is captured within the group at the Company A level, and the inflated site cost is transferred to Company B as an internal cost. Company B’s ‘thin margins’ are manufactured by the internal transfer price.
The following examples are drawn from public corporate records, company annual reports, CRO filings, and published disclosures. No allegation of improper conduct is made.
Glenveagh Properties plc (Euronext Dublin: GLV) describes itself explicitly as ‘vertically integrated’ in its Full Year Results 2025: ‘Our manufacturing-led, vertically integrated delivery model continues to differentiate Glenveagh.’ Its landbank of approximately 19,000 units was secured at approximately €32k per plot — less than 10% of Net Development Value. Glenveagh returned over €445 million to shareholders between 2021 and 2025 through buybacks and dividends while simultaneously lobbying for state supports to address housing ‘affordability.’

Conor Norton, Head of the School of Environment and Planning at TU Dublin and President of the Irish Planning Institute, stated in the Irish Times (October 2021): ‘Planners say they receive applications from certain developers who they know aren’t developers at all, but speculators seeking a grant of permission to increase land values.’ The former Chivers jam factory site in Coolock was purchased for approximately €2.5 million, rezoned, and listed for €25 million, a 10× return from the planning designation change alone.

**Developer and builder are the same group: ** Glenveagh and Cairn — together accounting for a large share of Ireland’s NACE 411/412 activity — operate fully integrated models within the same ultimate ownership.
**‘Vertical integration’ is a disclosed margin strategy: ** Glenveagh explicitly attributes ‘margin resilience’ to its vertically integrated model in investor communications.
**Land is acquired at a fraction of development value: ** Glenveagh’s own disclosure of a land bank at <10% of NDV quantifies the planning uplift that flows through the group.
**Project-level viability claims require group-level scrutiny: ** State agencies making funding decisions based on subsidiary-level accounts are examining one arm of a two-armed profit extraction mechanism.
These examples document the existence of the integrated structure and confirm it is the dominant model. They don’t establish, and this report does not allege, that any specific company has engaged in improper transfer pricing or acted unlawfully. The structural problem doesn’t require bad intent, the accounting dynamic emerges from the legal corporate structure itself. It is the law — specifically the absence of land value capture legislation and consolidated accounts requirements — that allows the €619k per-acre Dublin rezoning uplift to be privately retained rather than publicly captured.
