Dundrum · The area
Why house extensions and attic conversions in Dundrum are a familiar brief.
Dundrum's mixed housing brings mixed extension briefs. The pre-war and period semis around Churchtown and the village need careful planning conversation, conservation context and ACA boundaries shape the rear-extension scope, with detailing on the rear elevation needing to read against the original frontage. The Ballinteer, Sweetmount and Wesley mid-century estate semis have the most repeatable extension brief in the area: rear cavity-wall openings up cleanly for a single-storey extension under the 40 sqm threshold, often with a kitchen-dining open-plan layout opening to the garden. Attic conversions feature regularly across both stocks. The LUAS proximity and Dundrum Town Centre adjacency support a strong renovation market and most projects are well-developed by the time they reach us.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Dundrum, 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 Dundrum 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.

Common questions about house extensions and attic conversions in Dundrum.
Yes. Dundrum is a regular service area for us. Renovations, extensions and bespoke joinery in Dundrum and the surrounding Dundrum 14 corridor — from period red-bricks near the old village to the 1960s and 1970s semis off the Sweetmount and Wesley estates. 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.
Yes. We routinely build to architects’ and engineers’ drawings as the main contractor. You get one point of accountability on site.
Yes — we coordinate the engineer and assigned certifier as part of the project so the certification is in place at completion.
