Frequently Asked Questions
Your questions about loft conversions in Kensington, answered.
How much does a loft conversion cost in Kensington?
Loft costs in Kensington depend on the scheme far more than the floor area. Across W8, expect roughly £29,000–£39,000+ for a rooflight conversion, £39,000–£59,000+ for a rear dormer and £53,000–£69,000++ for a mansard or hip-to-gable. Structure, stair position and access drive the number. Buildaway itemises all of it before you commit.
How long does a loft conversion take in Kensington?
A Kensington loft conversion typically takes 6 to 10 weeks on site. A dormer runs nearer 6–7, a mansard or hip-to-gable 8–10 or more. That excludes the paperwork ahead of it: party-wall awards alone can take 4–8 weeks in W8 terraces and cannot be rushed. Buildaway starts that clock early.
Do I need planning permission for a loft conversion in Kensington?
Many Kensington loft conversions fall under permitted development, but not all. Around W8 a rear dormer is often acceptable while anything altering the front roof slope usually is not. Conservation-area designation and listed status remove permitted development rights entirely, so the Royal Borough of Kensington & Chelsea approval becomes essential. Buildaway establishes your position before drawing anything.
What types of loft conversion do you offer in Kensington?
All the main types: rooflight, dormer, hip-to-gable and mansard. In Kensington the choice is usually decided by the roof you have and the planning position, not by preference. Buildaway measures headroom and structure across W8 first, then tells you honestly which schemes are actually available to you.
Do Buildaway handle both design and construction for Kensington lofts?
Yes. Buildaway takes Kensington lofts from feasibility survey and structural design through party-wall notices, Building Control, steels, stairs, insulation, glazing and finish. One contract across every W8 project, so nobody can blame the engineer for the builder's work or vice versa.
Are your loft specialists local to Kensington?
Buildaway covers Kensington and the wider W8 area year-round. Having converted lofts on this housing stock repeatedly, we know its constraints before the survey starts - and we are nearby long after handover.
