Loft Conversions
Transform your unused attic into valuable living space
Loft Conversions Cornwall
That empty space above your head? It could be a bedroom, an office, a bathroom. Loft conversions add proper living space without eating into your garden — and most don't need planning permission.
Pitched roof, hipped roof, tight headroom — we've converted them all across Cornwall. Every loft has its quirks. We figure out what yours needs and make it work.
Structural calcs, building regs, steel beams, staircase, insulation, electrics, plastering — we handle the lot. You get a finished room with a certificate, ready to use.

Types of Loft Conversions
Dormer Loft Conversions
A box extension built out from your roof slope. Gives you headroom where the ceiling used to dive away. Works on most houses.
Hip-to-Gable Conversions
Got a hipped roof that slopes on all sides? We extend one end to a vertical gable wall. More usable floor space inside; works well on semis and detached homes.
Mansard Loft Conversions
We rebuild the roof with near-vertical walls, flat top. Maximum space, but bigger job — usually needs planning permission.
Velux / Rooflight Conversions
Already got enough headroom? Just add windows and a staircase. Quickest, cheapest option — no structural changes to the roof itself.

Planning & Building Regs
Good news: most loft conversions skip the planning queue. Permitted Development covers dormers to the rear and roof windows. Building Regs approval you do need — fire escape, structure, insulation — but we sort that.
Structural calcs, building control inspections, final sign-off certificate. We handle the paperwork. When you sell, solicitors see a proper job done properly.
Conservation area? Listed building? Tighter rules apply. We'll tell you what's realistic and handle any planning applications needed.
