Blackrock · The area
Why house extensions and attic conversions in Blackrock are a familiar brief.
Blackrock extension work splits by stock era. The Victorian and Edwardian seafront terraces and period semis through Booterstown and Monkstown have constrained extension scope shaped by ACA and protected-structure context. Rear extensions are typically held under the 40 sqm threshold and detailed against the period frontage with care taken on the visibility from public approach. Original 9-inch solid brick rear walls need engineer-signed structural opening. The mid-century estate housing inland is straightforward: cavity-wall construction opens up cleanly, generous gardens support full single-storey extensions under planning exemption, side returns feature where plot allows. Attic conversions feature across all stocks. The larger inland detached homes support double-storey extensions where planning allows.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Blackrock, the way it should be done.
Extensions are where most clients first speak to us. The reasons vary — a growing family, an attic that has become storage by default rather than design, a 1970s side return that is too cold to use — but the question is always the same: how do we add space to a house that is otherwise lovely, and have it feel like it was always there?
We run extensions end to end. Where you have an architect, we build to their drawings and become the single point of accountability through planning, structural design and construction. Where you do not, we coordinate the architect and engineer ourselves and quote the build to a clear specification before work starts.
Attic conversions are one of our most common projects — adding a bedroom with ensuite to an Irish three-bed semi is one of the highest-value moves a client can make, and it is squarely within our scope. Garage conversions follow the same pattern: insulation, blockwork, plastering, electrics, plumbing and joinery, all run by one team.
The work in Blackrock runs to the same specification we apply everywhere across Dublin and Leinster. Materials, sub-trade coordination, planning context and final certification are all managed from one studio. If your project is on the dublin side of the city, expect site visits within the working week and same-day responses on WhatsApp.
