What really impressed me was Cormac's honesty…”

Frequently Asked Questions
Your questions about loft conversions in Hammersmith, answered.
How much does a loft conversion cost in Hammersmith?
As a guide, loft conversion in Hammersmith (W6) runs about £35,000–£45,000 for a Velux or roof-light scheme, £45,000–£55,000 for a dormer, and £65,000++ 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 Hammersmith?
Six to ten weeks is realistic for Hammersmith, depending on scheme. The build is predictable; the approvals are what vary. Buildaway handles party-wall, Building Control and Hammersmith & Fulham Council consent in parallel with design so the W6 programme holds.
Do I need planning permission for a loft conversion in Hammersmith?
Many Hammersmith loft conversions fall under permitted development, but not all. Around W6 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 Hammersmith & Fulham Council approval becomes essential. Buildaway establishes your position before drawing anything.
What types of loft conversion do you offer in Hammersmith?
All the main types: rooflight, dormer, hip-to-gable and mansard. In Hammersmith the choice is usually decided by the roof you have and the planning position, not by preference. Buildaway measures headroom and structure across W6 first, then tells you honestly which schemes are actually available to you.
Do Buildaway handle both design and construction for Hammersmith lofts?
We do the whole thing. Buildaway surveys your Hammersmith 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 Brook Green and Ravenscourt Park to Building Control sign-off.
Are your loft specialists local to Hammersmith?
Yes. Buildaway works across Hammersmith and the surrounding W6 streets regularly, so we know the roof profiles around Brook Green and Ravenscourt Park and what Hammersmith & Fulham Council has accepted nearby. That precedent matters: knowing what got consented on the next street is often the difference between approval and refusal.
