London-Wide Coverage
Bedroom and En-Suite, Same Roofline
A loft bedroom with en-suite is built within a Velux-style conversion’s head-height — a genuine extra bedroom and bathroom, without a full dormer or mansard extension. Feasibility depends heavily on your existing plumbing routes, which we assess honestly, not optimistically.
Bedroom & En-Suite, Same Roofline
Built within a Velux-style conversion's head-height, not a full dormer extension.
Plumbing & Drainage, Assessed Honestly
En-suite feasibility depends on your existing plumbing routes — we assess this properly at survey rather than assuming.
Warm Roof Insulation, Always
A bedroom needs proper rafter insulation for year-round comfort, fitted as standard.
Ventilation Matters
Bathroom extraction and roof ventilation are planned in from the start to prevent condensation issues.
Bedroom Only, No Bathroom?
If you just want a bedroom, we can build without the en-suite — see our general Velux Loft Conversion page.
Fully Insured, Every Job
Public liability insurance covers every survey and installation we carry out.
