Number of Apartments Under Construction in Dublin Rises, But House Building Slows

The residential property landscape in the Dublin region is undergoing a notable shift. New data reveals that while multi-unit residential blocks are surging, traditional family home starts have experienced a sharp contraction.

There are nearly 25,000 flats under active construction across the Dublin area. This reflects a growing structural pivot toward high-density urban living alternatives as developers focus heavily on vertical residential infrastructure.

In contrast, the number of houses with planning permission where physical work has actually commenced has fallen. The trend shows that having valid legal authorization no longer guarantees immediate building site breakthroughs.

According to the official Housing Supply Monitor Report for the first quarter of the year, published on Monday by the Department of Housing, this divergence is reshaping the local property pipeline.

The balance of the housing stock in production is heavily weighted toward multi-unit complexes. Analysts note that this trajectory will determine inventory dynamics for both the rental and buying markets over the next few years.

Key Metrics From the Department of Housing Supply Monitor Report

The statistical returns submitted by the four local authorities in the Dublin region outline the exact state of active housing construction. The data shows a growing disparity between different types of residential developments.

The primary data points detailing the current Dublin residential property market include:

• Apartments Under Construction: There are exactly 23,474 flats currently being built across 202 active development sites.
• Year-on-Year Apartment Increase: The total number of apartments currently under construction represents a 1.2 percent increase compared to the same period last year.
• House Construction Decline: The number of traditional houses under construction fell by about 13 percent, dropping down to a total of 7,690 units in the first quarter.
• Completed Units within Activated Planning: Out of the total activated planning permissions, 8,462 residential units have been fully built.

This distinct shift highlight challenges for expanding families seeking low-density suburban accommodation. The building pipeline is increasingly prioritizing compact urban apartments over standalone houses.

The figures point to a substantial mismatch between the volume of projects getting authorized and those breaking ground. The slow translation of housing permissions into active sites limits near-term supply expansions for single-family residences.

Unactivated Planning Permissions Highlight Growing Dormant Pipeline

The report also draws attention to a substantial volume of approved residential developments that remain completely dormant. A significant backlog of authorized planning files has not translated into active development sites.

The trends regarding unactivated construction permissions in the Dublin region include:

• Unactivated Apartments: Planning permission for more than 41,000 apartments has not been activated, meaning construction has not yet started.
• Rise in Dormant Approvals: This volume of unstarted apartment permissions represents an increase of more than 5 percent compared to the first quarter of last year.
• Overall Residential Share: More than 80 percent of all residential units with valid planning permission in the Dublin area are apartments.
• Total Authorized Pipeline: Out of 78,658 total unit permissions granted for the Dublin area, a total of 31,936 have been activated.

The high volume of unactivated planning permissions suggests that economic or structural bottlenecks are delaying projects after approval. Developers face underlying constraints that slow the transition from blueprints to physical builds.

The Department of Housing noted that decisions on planning applications are still awaited for 13,600 housing units. This is down significantly from a previous backlog of 34,400 units, indicating an improvement in processing speeds.

As the nearly 25,000 apartments currently on 202 active sites near completion, the lack of parallel house construction could tighten the suburban market. Balancing these two distinct property types remains a critical goal for regional planners.
