House Extensions, Attic & Garage Conversions in Rathfarnham.

Rathfarnham · The area

Why house extensions and attic conversions in Rathfarnham are a familiar brief.

Rathfarnham's extension briefs are dominated by the mid-century estate stock through Nutgrove and Butterfield and the larger detached homes towards Templeogue and Knocklyon. The estate housing typically supports the standard mid-century extension template: rear cavity-wall opening up cleanly for a single-storey extension under the 40 sqm threshold, often with a kitchen-dining open-plan layout opening to the garden. The larger Knocklyon and Templeogue detached stock supports more ambitious briefs: double-storey extensions where planning allows, wraparound extensions combining side and rear, full kitchen-dining-living open-plan layouts. Attic conversions feature regularly, the Rathfarnham roof pitches typically work well for adding a bedroom and ensuite with a rear dormer. Older village stock and pre-war semis around the castle carry conservation context and need more careful detailing.

House Extensions, Attic & Garage Conversions · How we run it

House Extensions, Attic & Garage Conversions in Rathfarnham, 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 Rathfarnham 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.
