Celbridge · The area
Why house extensions and attic conversions in Celbridge are a familiar brief.
Celbridge extension briefs split by stock era. The older village terraces and pre-war stock around Main Street need careful planning conversation, particularly around Castletown House and the Main Street conservation context, with rear extensions detailed against the original frontage. The 1980s and 1990s estate housing through the middle carries the standard modern extension template: cavity-wall construction opens up cleanly at the rear, generous gardens support full single-storey extensions under the 40 sqm threshold, side returns feature where plot allows. The newer Castletown and Hazelhatch estate growth supports the same scope plus double-storey extensions on the larger plots where planning supports. Attic conversions feature across all stocks with rear dormer schemes typical. The M4 corridor logistics make structural-engineer site visits straightforward from our Dublin base.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Celbridge, 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 Celbridge 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 kildare side of the city, expect site visits within the working week and same-day responses on WhatsApp.
