Glazed and glass-box rear extensions in County Fermanagh
Full-height glass, slim frames and big rooflights for the most open rear room. We design and build rear extensions across County Fermanagh, from Enniskillen and Enniskillen to Enniskillen, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer. Semis and detached houses are typical of County Fermanagh, and many have room for a rear extension within Northern Ireland's permitted development limits.
