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?
Every house extensions and attic conversions project in Sandyford is run personally by Marcin's in-house team — site visits within the working week on the Dublin side of the city, and same-day answers on WhatsApp. For the full detail on how we approach house extensions and attic conversions — process, specification and certification — see the extensions service page.

Most rear extensions under 40 sqm fall under planning exemption, subject to conditions on height, height to eaves, and proximity to boundaries. We will tell you at first site visit whether your project is exempt or needs planning, and we coordinate the application if it does.
Most Dublin three-bed semi attic conversions run 8 to 12 weeks from the day the scaffold goes up. Adding an ensuite extends it slightly. We give a written schedule and update it weekly.
