Homes in Belfast, and what that means for your bathroom
- Rows of 19th-century red-brick terraces built for mill and factory workers, especially in north, west and east Belfast.
- Post-war estates on the edge of the city, built after the 1941 Blitz and later slum clearance.
- Larger Victorian and Edwardian villas around Malone and south Belfast, many since split or extended.
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.
Post-war houses usually have solid concrete ground floors and simple layouts, which suits new flooring, but wiring and pipework may be original and worth replacing while the room is stripped.
