Caerphilly's 1930s semis are the classic loft conversion house: hipped roof, solid construction, and a loft big enough for a double bedroom and en-suite once the hip is built up to a gable. The borough's terraces convert well too — many have the pitch for a Velux conversion or a compact rear dormer home office.
Most loft conversions in Caerphilly fall under permitted development, so there's often no planning application at all — just building regulations, which we handle end-to-end with Caerphilly County Borough Council, from structural calculations to the fire-safety details that make the new floor legal. See our work in Caerphilly or all our loft conversion services.
Turning a three-bed semi into a four-bed with an en-suite typically costs far less than the jump to a four-bed house — and adds serious value across Caerphilly borough.
The signature conversion for the borough's 1930s semis: build the sloping hip up into a full gable, add a rear dormer, and the cramped loft becomes a genuine master suite.
A rear dormer gives flat ceilings and full-height space — the difference between a loft you visit and a bedroom you live in. Ideal for terraces and semis alike.
For valley terraces with a decent pitch, rooflights alone create a bright home office or guest room at the lowest cost, with no alteration to the roofline.
