An €82 Million Apartment Block, a Cooling Volume Market, and the Banking Bet on 7,000 New Homes
The headline number this month is impossible to ignore: a single transaction at the Glass House, Glass Bottle site in Dublin's Ringsend/Poolbeg docklands registered at €82.1 million VAT-exclusive — the largest bulk apartment purchase recorded in the Property Price Register this year, and a figure that dwarfs the next-largest transaction by a factor of 25. Strip out that outlier and the broader market tells a more nuanced story: Dublin average prices are up 25.8% quarter-on-quarter to €679,456, but transaction volumes are down 21% — fewer deals, higher values, a market where institutional money is concentrating into large-scale new builds while the secondary market cools. Meanwhile, the planning pipeline is signalling future supply: 1,624 applications received in July–August, with 946 residential units in the queue — but a shortage of 6,000 engineers, flagged by Engineers Ireland this week, raises a serious question about whether the construction sector can actually deliver.

The Investigation: Where the Money Is Moving
A deeper look at the transactions registered in the Property Price Register over the June–August 2026 period reveals a market in transition. The headline is the €82.1 million Glass Bottle deal, but the real story is in the county-level data: Dublin prices have surged while volumes have collapsed, Kildare has quietly become the second most expensive county in the state, and Waterford and Clare are showing the steepest volume declines of any major county. The data suggests a market bifurcating between institutional-scale new builds and a secondary market that is simply not clearing at current prices.
Notable Transactions Registered (June–August 2026)
| Address | County | Price | Type | Signal |
|---|---|---|---|---|
| Glass House, Bottle Maker Place, Glass Bottle | Dublin | €82,147,787 | New Apt (VAT excl.) | Bulk Institutional |

County Price Tracker: June–August 2026 vs March–May 2026
The county-level comparison reveals a market pulling in two directions. Dublin prices have surged on lower volumes — a sign of institutional concentration rather than broad-based demand. The commuter counties of Kildare and Meath are holding up, while the western and southern counties show more mixed signals. Waterford and Clare are the standout concerns: both have seen volume declines of more than a third, suggesting buyers and sellers are at an impasse on price.
| County | Avg (Jun–Aug) | Avg (Mar–May) | Change | Vol (Jun–Aug) | Vol (Mar–May) | Vol Change |
|---|---|---|---|---|---|---|
| Dublin | €679,457 | €539,933 | +25.8% | 1,588 | 2,016 | −21.2% |
| Kildare | €456,840 | €397,824 | +14.8% | 318 | 386 | −17.6% |
| Wicklow | €462,003 | €469,956 | −1.7% | 173 | 222 | −22.1% |
| Cork | €350,717 | €330,735 | +6.0% | 647 | 925 | −30.1% |
| Meath | €353,077 | €351,509 | +0.4% | 204 | 269 | −24.2% |
| Galway | €328,127 | €291,790 | +12.5% | 200 | 385 | −48.1% |
| Limerick | €294,864 | €276,270 | +6.7% | 154 | 242 | −36.4% |
| Waterford | €242,834 | €258,182 | −5.9% | 140 | 220 | −36.4% |
Planning Applications: The Pipeline Breakdown (July–August 2026)
The 1,624 planning applications received in July–August 2026 represent the forward-looking supply signal. Donegal leads all counties with 244 applications — a figure that reflects persistent rural housing demand in the north-west, where one-off housing remains the dominant form of new supply. Of the 1,624 total applications, 1,135 are standard permission requests and 273 are retention applications — the latter representing 16.8% of all applications, a ratio that suggests a significant volume of unauthorised development being regularised after the fact.
| Planning Authority | Applications | Notable |
|---|---|---|
| Donegal County Council | 244 | Rural housing, one-off dwellings, telecom infrastructure |
| Galway County Council | 149 | One-off rural, agricultural, commercial change of use |
| Tipperary County Council | 143 | Residential extensions, agricultural |
| Meath County Council | 122 | Commuter belt residential |
| Laois County Council | 109 | Midlands residential and agricultural |
| Waterford City & County Council | 95 | Mixed residential and commercial |
| South Dublin County Council | 61 | Urban residential and commercial |
| Dublin City Council | 52 | Urban intensification, extensions |
The Connections: What the Transactions Don't Tell You Alone
The Property Price Register is a rearview mirror — it shows where money has already moved. The real intelligence comes from connecting those transactions to the corporate structures behind them, the banking decisions that enable them, and the planning pipeline that will determine whether supply can ever catch demand. This month, three themes emerge from the data: the institutionalisation of Dublin's new-build market, the banking sector's calculated bet on large-scale housebuilding, and a planning system under structural strain from a shortage of the engineers needed to deliver what it approves.
The Radar: Three Signals Worth Watching
The Deep Dive: Two Stories Behind the Numbers
Two entities this month deserve deeper investigation than a table row can provide. The first is the Glass Bottle site in Ringsend — a transaction so large it distorts the entire Dublin market statistics. The second is the Castlethorn group, whose CRO footprint reveals the corporate architecture behind one of the most ambitious housing delivery programmes in the state. Together, they illustrate the two forces shaping Irish property in 2026: institutional capital concentrating into large-scale new builds, and developer groups scaling up to meet it.
Glass House, Glass Bottle Site, Ringsend — Ireland's Largest Apartment Transaction of 2026
The Glass House, Bottle Maker Place, Glass Bottle, Dublin is a new-build apartment development on the former Irish Glass Bottle site in Ringsend/Poolbeg — one of the most significant brownfield regeneration projects in the state. The site, which once housed the Irish Glass Bottle Company, has been the subject of planning and development activity for over two decades. The transaction registered on 22 July 2026 at €82,147,787 VAT-exclusive represents a bulk institutional purchase of what the Property Price Register classifies as a "New Dwelling house/Apartment."
| Detail | Value |
|---|---|
| Transaction price | €82,147,787 (VAT-exclusive) |
| Property type | New Dwelling house/Apartment |
| Transaction date | 22 July 2026 |
| Process date | 1 August 2026 |
| Eircode | Not assigned (new development) |
| VAT status | VAT-exclusive (new build) |
| Full market price | Yes |
| Implied unit count (at Dublin avg) | ~180 apartments |
The question for the next 12 months: will the remaining phases of the Poolbeg SDZ follow the same institutional ownership model, or will the planning framework require a proportion of units to be sold to owner-occupiers or delivered as social/affordable housing?
Castlethorn Old Conna Unlimited Company — The Corporate Vehicle Behind 7,000 Homes
Castlethorn Old Conna Unlimited Company (CRO number 776367) was registered on 22 November 2024 at Overend House, Dundrum Town Centre, Sandyford Road, Dublin D16 A4W6. The company is classified under NACE code "Activities of holding companies" — a structure typical of a development vehicle being capitalised ahead of a major build programme. With €1 million authorised capital and just €1 issued, the company is in its early capitalisation phase.
| Detail | Value |
|---|---|
| Company number | 776367 |

The question for 2027: when Castlethorn's first JV sites come through the planning system, will they include affordable purchase units, or will the entire programme be delivered as build-to-rent?

One to Watch: Castlethorn Old Conna Unlimited Company
Castlethorn Old Conna Unlimited Company
| Metric | Value |
|---|---|
| Company type | ULC — Private Unlimited Company |
| Authorised capital | €1,000,000 |
| Issued capital | €1.00 |
| JV fund size | €220M (Avenue Capital) |
| State co-investment | €150M (ISIF) |
| Bank co-investment | €70M (AIB + BoI) |
| Target homes | Up to 7,000 |
What they do: Castlethorn Old Conna Unlimited Company is the holding vehicle for the Castlethorn development group's joint venture with Avenue Capital, the US investment firm. The company was registered in November 2024 — just 18 months ago — and is already at the centre of one of the largest private housing delivery programmes in the state. The Castlethorn group, associated with developer Joe O'Reilly, has a long track record in Irish residential development including Dundrum Town Centre and multiple suburban schemes.
Why it matters: The unlimited company structure means Castlethorn Old Conna's accounts will not be publicly filed — making it impossible for the public to scrutinise the financial terms of a programme that includes €150 million of state money via ISIF. The combination of state capital, retail bank equity, and a US fund manager in a single vehicle is a new model for Irish housing delivery. If it works, it could be replicated across the sector. If it doesn't, the state is exposed. The number that matters: €1 — the issued share capital of a company at the centre of a €220 million housing programme. The real capital is off-balance-sheet, in the fund structure. Watch for the first planning applications from this JV in Q1 2027.
The Broader Picture: Courts, Companies, and the Month Ahead
The Companies Registration Office
The CRO data for the period reflects the broader corporate activity underpinning the property market. The most significant CRO finding this month is the confirmation of Castlethorn Old Conna Unlimited Company (776367) as the holding vehicle for the Castlethorn/Avenue Capital housing JV — a company registered just 18 months ago with €1 million authorised capital that is now at the centre of a €220 million housing programme. The unlimited company structure means its accounts will not be publicly filed. New company formations in the property and construction sectors continue at pace: the CRO registered 0 new companies in the period, with 0 companies showing activity.

The Irish Courts
No new judgments were delivered in the July–August 2026 period that directly involve the companies or properties featured in this month's data. However, the courts have a substantial body of recent case law on planning permission challenges that is directly relevant to the development pipeline. Three cases from the High Court are worth noting for their ongoing relevance to the planning system: the Crofton Buildings Management CLG v An Bord Pleanála case established that height restriction contraventions cannot be overlooked in SHD planning decisions; the Flannery v An Bord Pleanála case confirmed that a developer's financial situation is irrelevant to planning decisions; and the Doyle v An Bord Pleanála case addressed the harmless error doctrine in data centre planning permissions.
| Citation | Parties | Subject | Why It Matters |
|---|---|---|---|
| [2022] IEHC 704 | Crofton Buildings Management CLG v An Bord Pleanála | SHD planning permission quashed | Height restriction contraventions cannot be overlooked; Fitzwilliam DL Limited developer affected |
| [2022] IEHC 83 | Flannery & Ors v An Bord Pleanála | Residential on Z9 zoned lands quashed | Developer financial situation irrelevant to planning; Templeogue Synge Street GAA Club developer |
| [2025] IEHC 158 | Doyle & Ors v An Bord Pleanála | Data centre planning permission | Harmless error doctrine in planning; Art Data Centres Limited developer; relevant to large-scale development approvals |
Property Markets & Plans
The commercial property market in Dublin city centre showed activity this month, with the €1.25 million transaction at 23–27 College Green, 6–7 Church Lane, 25–27 St. Andrew Street representing a notable city-core commercial deal. The planning pipeline for the period includes a change-of-use application in Moycullen, Galway (retail to café), and a new 2-bed detached dwelling in Newcastle, Galway — both indicative of the small-scale commercial and residential activity that dominates the non-Dublin planning queue.
| Application | Authority | Type | Signal |
|---|---|---|---|
| Unit 1 An Fuarán, Moycullen, Galway — change of use retail to café | Galway County Council | Permission | Retail-to-hospitality conversion; rural town centre activity |
| 2 Dangan Court, Newcastle, Galway — new 2-bed detached dwelling | Galway City Council | Permission | Infill residential; urban densification at small scale |
| Kilcornan, Galway — 615 sqm one-off house (consequent permission) | Galway County Council | Permission Consequent | Large one-off rural dwelling; 615 sqm floor area is significantly above average |
| Ballyhasky, Newtowncunningham, Donegal — 18m telecom monopole | Donegal County Council | Permission | Rural telecoms infrastructure; connectivity investment in north-west |
The Month Ahead
The Irish property market enters September 2026 with a clear structural story: institutional capital is concentrating into large-scale new builds, the secondary market is cooling on volume, and the planning pipeline is pointing toward future supply that may take years to materialise. The Glass Bottle transaction is the defining data point of the quarter — not because €82 million changed hands, but because of what it reveals about who is buying, what they are buying, and what they plan to do with it. The autumn will test whether the volume decline in Dublin and the regional markets is seasonal or the beginning of a more sustained correction.
What to Watch in September 2026:
- First planning applications from the Castlethorn/Avenue Capital JV sites — the key test of whether the €220M fund translates into actual housing delivery
- Q3 2026 mortgage approval data from the Banking & Payments Federation Ireland — will confirm whether the volume decline in Dublin is demand-driven or supply-driven
- Any judicial review challenges to Poolbeg SDZ permissions — the legal risk that could delay the next phase of Ireland's largest urban regeneration project
- ECB rate decision in September — a hold or cut will determine whether the volume decline in regional markets is temporary or structural
