permit so much as a rooflight - the lease and the structure decide, not the
ambition. Buildaway's St John's Wood loft team surveys, secures consent, then
builds.

Frequently Asked Questions
Your questions about loft conversions in St John's Wood, answered.
How much does a loft conversion cost in St John's Wood?
As a guide, loft conversion in St John's Wood (NW8) runs about £28,000–£39,000+ for a Velux or roof-light scheme, £39,000–£59,000+ for a dormer, and £53,000–£69,000++ for a hip-to-gable or mansard. UK guides put dormers around £40,000–£60,000 and mansards £50,000–£80,000, with London consistently at the top of those ranges. Buildaway fixes your figure in writing after survey.
How long does a loft conversion take in St John's Wood?
A St John's Wood 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 NW8 terraces and cannot be rushed. Buildaway starts that clock early.
Do I need planning permission for a loft conversion in St John's Wood?
Many St John's Wood loft conversions fall under permitted development, but not all. Around NW8 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 Westminster City Council approval becomes essential. Buildaway establishes your position before drawing anything.
What types of loft conversion do you offer in St John's Wood?
Rooflight, dormer, hip-to-gable and mansard - Buildaway builds all four in St John's Wood. The right answer for your NW8 roof depends on ridge height, the stair, and what Westminster City Council will consent. We establish that before proposing a design.
Do Buildaway handle both design and construction for St John's Wood lofts?
We do the whole thing. Buildaway surveys your St John's Wood roof, designs a scheme that is actually consentable, serves the notices, and builds it with our own team. One point of contact from feasibility around Hamilton Terrace and Wellington Road to Building Control sign-off.
Are your loft specialists local to St John's Wood?
Yes, St John's Wood is core Buildaway territory. We convert lofts across NW8 regularly and understand both the buildings around Hamilton Terrace and Wellington Road and the Westminster City Council policies that govern them.
