House Extensions, Attic & Garage Conversions in Mount Merrion: Open-plan ground floor rear extension with high ceilings and large rooflights

Mount Merrion · The area

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

Mount Merrion's 1950s and 1960s estate housing supports a highly repeatable extension brief: cavity-wall construction throughout, consistent layouts across the neighbourhood, generous rear gardens deep enough for full single-storey extensions under the 40 sqm threshold, and standard 2.4m ceiling heights. The typical Mount Merrion extension is a kitchen-dining open-plan rear extension combining the original separated rooms into one larger family space opening to the garden. Attic conversions feature regularly, the Mount Merrion roof pitches typically work well for adding a bedroom and ensuite with a rear dormer. Garage conversions feature for a home office. Side returns are limited by the typical Mount Merrion plot geometry. The consistency of the stock keeps extension briefs predictable in scope and schedule.

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

House Extensions, Attic & Garage Conversions in Mount Merrion, 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 Mount Merrion 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.
