Garden Rooms Larne

Larne sits on an exposed stretch of the Antrim coast, and that single fact shapes every garden room we build here. Salt air, onshore wind and driving rain are not incidental — they decide the cladding, the sealing and the fixings.

Building on the Antrim Coast

We have been building since 2009 and we specify differently for coastal jobs than inland ones. Timber cladding facing the sea at Ballygally will need attention within a few years; the same board inland will last far longer. On exposed Larne sites we normally recommend composite for that reason, and we will say so even though it costs more up front.

What Exposure Changes

Three things. Fixings and flashings need to resist wind uplift, not just look neat. Sealing around openings has to cope with rain driven horizontally rather than falling vertically. And insulation matters more because wind chill strips heat from a poorly detailed building far faster than still air does. None of this is visible in a photograph, which is why cheap coastal builds fail early.

Rooms We Build Around Larne

Home offices are the most common request, followed by gyms and studios. Compact pods suit the narrower terraced plots closer to the town centre. We also carry out single-storey extensions and conservatory roof conversions, and supply composite cladding and porcelain paving separately if you are working with your own builder.
