Clontarf · The area
Why house extensions and attic conversions in Clontarf are a familiar brief.
Clontarf's Edwardian seafront terraces have constrained extension scope, plot widths are narrow, planning context is heavy (ACAs throughout, many protected structures), and the front-elevation conservation requirements affect what can be done at the rear. Where rear extensions are possible, the typical brief is a small single-storey kitchen extension below the 40 sqm threshold, with careful detailing so the rear reads against the original frontage. The Tudor-revival semis on Castle Avenue and Vernon Avenue have more rear-plot room and the brief is often a wraparound extension combining a side return with the rear, where the cavity construction makes the structural opening straightforward. Attic conversions feature regularly across both stocks (Edwardian roofs support a full habitable conversion with a rear dormer or side rooflights). The Marino terraced housing inland has tighter plots but standard planning context.
House Extensions, Attic & Garage Conversions · How we run it
House Extensions, Attic & Garage Conversions in Clontarf, 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 Clontarf 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 Clontarf.
Yes. Clontarf is a regular service area for us. Renovations and extensions in Clontarf — Edwardian red-bricks along the seafront, Tudor-style semis along the Castle Avenue and Vernon Avenue corridors, and the inland Marino terraces. Period detailing, careful planning, and a service area that knows the coastal weather. 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.
