Pitched and lean-to roof rear extensions in County Tyrone
Lean-to, gable and hipped roofs that give a vaulted ceiling. Across County Tyrone we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Omagh, Strabane and Dungannon.

Pitched roofs suit the cottages and slate-roofed houses in parts of County Tyrone. Semis and detached houses are typical of County Tyrone, and many have room for a rear extension within Northern Ireland's permitted development limits.
