House Extensions, Attic & Garage Conversions in Dún Laoghaire.

Dún Laoghaire · The area

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

Dún Laoghaire's Victorian and Edwardian period stock has constrained extension scope shaped by the heavy planning context (significant ACAs, protected structures common, particularly around the seafront and Sandycove). The classic D-L extension brief is a careful single-storey rear extension under the 40 sqm threshold, detailed so it reads against the original period rear elevation and respects the streetscape from above. Side returns feature where plot geometry allows. Original 9-inch solid brick rear walls need engineer-signed structural opening for any wide steel; the work is more involved than a cavity-construction equivalent. Attic conversions feature on the larger period stock where the roof pitch supports it, often involving a rear dormer rather than a side-rooflight scheme. Modern apartments and townhouses by the East Pier carry simpler extension scope but rarely come up for extension work.

House Extensions, Attic & Garage Conversions in Dún Laoghaire, 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 Dún Laoghaire 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.
