Full-house replacement for valley stone terraces across Cwmbran

Valley stone terraces on Cwmbran's new-town 1960s and 70s estates with a mix of semis streets share a specific set of quirks. Stone reveals are dressed, not rendered — the frame sits directly against masonry so packing is critical. Valley terraces are frequently unlisted but often within conservation areas — colour choice tends to be a factor even when profile isn't formally restricted. Front-to-back schedule: front elevation first, sides, then rear; one team on site each day; rubbish cleared nightly. Foil colour on the front elevation reads sympathetic when it lifts a warm undertone from the brick — pure white can look stark. Original leaded lights are worth preserving; specialist restorers pay to buy them if the client wants to sell rather than store. Grass verges take skip weight fine when boarded — check with the council before dropping directly onto turf. Typically 2–4 days depending on count, with a final snag visit a week later. External timber cladding at the head of the window is easily matched to modern PVC trim in a coordinated foil. Developer window frames are typically low-spec multi-chamber uPVC — the profile is fine, the hinges and glass are the fail point. The load path through the bay corner post pulls diagonally when the roof sags; reinforced steel accepts it, aluminium alone deflects. Gravel front gardens mean the crew boards from the van to the elevation to avoid tracking stones inside. Post-war doors sat on a raised timber threshold; a Part-M part-plate replaces it cleanly at composite door install. Stone cills usually project only 40mm — the frame drip has to clear the projection without over-hanging.
