Luxury Builders in Camden
Premium house extensions, renovations and loft conversions in Camden, London.
Builders in Camden, NW1
Camden is one of North London's most iconic and architecturally rich neighbourhoods, where elegant Georgian townhouses, substantial Victorian conversions and characterful period properties create a residential landscape of extraordinary quality and variety. From the refined crescents of Camden Square to the handsome terraces along Gloucester Avenue and the canal-side properties near Regent's Canal, Camden offers a sophisticated living environment that demands construction work of the highest standard. Alstruct Ltd delivers premium building services tailored to Camden's distinguished housing stock.
The Georgian and Victorian architecture that defines much of Camden presents both exceptional opportunities and specific challenges. Many properties feature original cornicing, ceiling roses, sash windows and ornate plasterwork that must be preserved and complemented by any new construction. Rear extensions in Camden often incorporate large-format glazing to flood period interiors with natural light, while loft conversions add valuable accommodation within the existing roofline. Victorian conversions — where larger houses have been divided into flats — can sometimes be reconfigured back into single family homes, a specialist area where Alstruct excels.
Camden falls within the London Borough of Camden, which administers numerous conservation areas including Camden Square, Camden Town, and Regent's Park. These designations impose strict controls on external alterations, materials and design, requiring expert planning navigation. Alstruct's team has deep experience working within Camden Council's planning framework, preparing applications that respect conservation area character while delivering the ambitious, design-led results our clients expect.

Camden Town and Kentish Town are Victorian and Georgian terraces around Camden Square, Gloucester Crescent and the Castlehaven side, with warehouse and mews conversions near the canal. Rear extensions and lower-ground dig-outs are the typical Camden projects, plus closet-wing infills on the terraces; most sites are tight, so logistics and party walls are planned early.
Camden Square, Camden Town, Primrose Hill and Regent's Canal are conservation areas, and Camden Council has a detailed basement policy requiring structural and hydrology reports. Most Camden extensions we price fall between £2,500 and £4,000 per m², so a 25–30 m² kitchen extension is roughly £75,000–£120,000 fitted out; our house extension cost guide breaks the numbers down. We check permitted development rights at the first visit and deal with Camden Council in-house.

Loft conversions in Camden
Camden's Victorian terraces suit rear dormers and, on the wider streets, mansard roof extensions; Camden's guidance prefers a traditional mansard on traditional buildings and rarely supports front dormers.
Expect £45,000–£75,000 for a dormer loft with a bedroom and en-suite, £60,000–£100,000+ for a mansard and from £25,000 for a Velux conversion; the loft conversion cost guide has the breakdown. For a Camden loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.
Renovations and refurbishment in Camden
Camden refurbishments are usually complete reworks of period houses and flats, including new services, bathrooms and bespoke joinery. Typical Camden refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. See our renovation cost guide for realistic budgets. Camden projects are run by a single project manager under a JCT contract, with a written specification and a 10-year workmanship warranty.

Common questions about building in Camden
Do I need planning permission for an extension in Camden?
Houses, but not flats or maisonettes, keep national permitted development rights for a single-storey rear extension of 3m (attached) or 4m (detached), up to 6m or 8m through prior approval, and for most rear dormers within 40 cubic metres on a terrace or 50 on other houses. Parts of Camden fall in the Camden Town, Primrose Hill, Regent's Canal, Camden Square, Jeffreys Street and Kentish Town conservation areas. There a single-storey rear extension can still qualify, but side extensions, two-storey rear extensions, cladding and roof additions need permission. A borough-wide Article 4 direction means any basement needs planning permission from Camden Council. Our permitted development guide explains the limits.
What does Camden Council expect for mansards and dormers in Camden?
Camden Planning Guidance: Home Improvements (January 2021) sets the approach. Dormers should be subordinate to the roof slope and keep even distances to the ridge, eaves and party walls; in conservation areas they should leave more of the slope untouched. Front dormers on an unbroken roofscape are unlikely to be supported, and the guidance suggests a rear dormer with front rooflights instead. On traditional buildings a traditional mansard is preferred, with the lower slope set behind the parapet and the original cornice, parapet and chimneys kept.
What does a mansard loft conversion cost in Camden?
On Camden's Victorian and Georgian terraces a mansard loft conversion typically costs £60,000–£100,000+ including VAT, with prime central schemes at £120,000–£150,000. The figure depends on the roof structure, the parapet and party wall details and the finish inside. Our mansard loft conversion cost guide sets out what is included. In Camden's conservation areas a roof addition needs planning permission, so the application is part of the programme.
