Dublin 4 · The area
Why house extensions and attic conversions in Dublin 4 are a familiar brief.
Dublin 4 extension work runs at the highest spec spectrum. The Victorian and Edwardian period stock in Donnybrook, Sandymount and Ailesbury has constrained extension scope shaped by the heaviest ACA and protected-structure context in Dublin. Rear extensions are detailed in careful conversation with the conservation officer, typically held under the 40 sqm threshold, and articulated against the original period rear elevation. The larger Ailesbury and Shrewsbury homes support more ambitious briefs where planning supports: side returns combining with the rear into wraparound extensions, double-storey rear extensions on the larger plots where streetscape allows, often with glass roofs and high-spec glazing systems. Original 9-inch solid brick rear walls need engineer-signed structural opening for any wide steel. Attic conversions feature on the larger period stock where roof pitches support, usually with a rear-dormer scheme. Modern apartments and townhouses near the docklands rarely come up for extension work.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Dublin 4, 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 Dublin 4 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.
