Homes in Derry/Londonderry, and what that means for your en-suite
- Georgian, Victorian and Edwardian buildings in and around the walled city.
- Designated a new town in 1969, so many estates date from the late 1960s and 1970s.
In a conservation area or a listed building, you may need consent for changes visible from outside, such as windows or vents. Check with the council's planning team before you start.
Older terraces and town houses often have uneven walls and floors, lath-and-plaster ceilings and old wiring. Expect more making good than in a newer house, and keep the 10% contingency for what turns up behind the old units and tiles.
Houses built quickly in the 1960s and 70s can have poor insulation, thin partition walls and dated wiring. Check the walls and floor when the old room is stripped, and consider insulating while the walls are open.
