Stillorgan · The area
Why house extensions and attic conversions in Stillorgan are a familiar brief.
Stillorgan's post-war and 1960s detached and semi-detached stock supports a high-volume extension brief: cavity-wall construction throughout, generous rear gardens deep enough for full single-storey extensions under the 40 sqm threshold, side return potential on the larger plots, and standard 2.4m ceiling heights that work with single-storey schemes. The typical Stillorgan extension is a kitchen-dining-living open-plan rear extension combining the original three small rooms into one large space. Attic conversions feature regularly, the Stillorgan roof pitches support a full habitable conversion with a rear dormer or side rooflights. Garage conversions feature in the larger detached stock to add a home office or utility. Double-storey extensions are less common but feature on the larger plots where planning supports.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Stillorgan, 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 Stillorgan 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.

Common questions about house extensions and attic conversions in Stillorgan.
Yes. Stillorgan is a regular service area for us. Renovations, extensions and bespoke fitted joinery in Stillorgan. The post-war and 1960s detached and semi-detached housing across Stillorgan, Mount Merrion and the surrounding south-county streets is squarely in our service area. If your project sits in this area we will arrange a site visit, give you an honest indication of scope and timeline at the first meeting, and follow up with a written fixed-price quotation.
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.
