Single-storey rear extensions in County Fermanagh
Ground-floor space across the back of the house, usually for a kitchen, dining or family 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 depth of 3 to 4 metres keeps many single-storey rear extensions in Enniskillen within permitted development, subject to the house's planning history. County Fermanagh has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

FAQ
Questions people ask
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
Can I stay in the house during the build?
Usually yes. The noisiest, dustiest stage, removing the back wall, is kept to the final weeks and screened off. Most families set up a temporary kitchen elsewhere in the house.
Will the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.
Do you cover all of County Fermanagh?
We cover 1 towns and districts in County Fermanagh, including Enniskillen.
