Sandyford · The area
Why house extensions and attic conversions in Sandyford are a familiar brief.
Sandyford's 1970s and 1980s housing typically sits on generous rear plots with cavity-wall construction throughout, both factors that make rear extensions straightforward to scope structurally. Most semis off Blackthorn Drive and Sandyford Hall have rear gardens deep enough to support a single-storey extension under the 40 sqm planning exemption threshold, and the cavity construction means the back wall opens up for a wide steel cleanly. Attic conversions are also a high-volume Sandyford brief: most properties have roof pitches that support a full habitable conversion with a dormer or rooflights and an ensuite. Garage conversions feature in the larger detached stock to add a home office or utility. The newer Stepaside and Carrickmines stock supports the same range with the added option of side returns where plot geometry allows.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Sandyford, 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 Sandyford 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.
