Why NW6 is ideal for loft conversions
NW6 has one of the highest concentrations of convertible Victorian and Edwardian housing in North London. Streets like Sumatra Road, Crediton Hill and Loveridge Road are lined with terraces that have excellent ridge heights and straightforward roof structures — perfect for rear dormer or L-shaped conversions.
A loft conversion in NW6 typically adds £100,000–£220,000 to the property value. With property prices rising in West Hampstead and Kilburn, converting your loft is often a far better investment than moving.
We're based on Finchley Road — the border between NW3 and NW6. We work in West Hampstead, Kilburn, Brondesbury, Queens Park and Kilburn Park every week. We know which streets fall under Brent Council vs Camden Council, and how planning rules differ between the two boroughs.
NW6 areas we build in
NW6 spans two boroughs with different planning rules. We know both inside out.
West Hampstead
Victorian and Edwardian terraces with outstanding conversion potential. Most streets suit rear dormers under PD. Growing popularity means strong property value uplift from loft conversions.
Kilburn
Excellent stock of Victorian terraces, many with generous ridge heights. L-shaped dormers are popular here, creating substantial master suites. Good scaffolding access on most streets.
Brondesbury
Larger Edwardian and Victorian properties, some detached. Hip-to-gable conversions work well for semis. Conservation area in parts — we handle all heritage requirements.
Queens Park
Conservation area with charming Edwardian terraces. Mansard or sympathetic dormer designs required. We have extensive experience with Brent Council's conservation officers.
Kilburn Park
Mix of Victorian terraces and mansion blocks. Terraces offer excellent loft potential with rear dormers under permitted development. Close to our Finchley Road office.
Two Borough Expertise
NW6 is split between Camden and Brent councils with different planning policies. We know both authorities and handle all applications, whichever borough your property falls in.
"Ross and team completely transformed our loft into a stunning master suite with en-suite and walk-in wardrobe. The attention to detail was exceptional — from the bespoke eaves storage to the Juliet balcony. Finished on time and exactly on budget."Cirus RehmanHomeowner, Hampstead NW3
