Camden's mix of Victorian terraces and Regency-era housing offers real loft potential. TrustBuilt Projects builds dormer, L-shaped and mansard conversions across Camden Town, Kentish Town and the edge of Primrose Hill (NW1, NW5, NW3), with the whole build managed by us.
Camden's housing is varied — solid Victorian terraces through Kentish Town (NW5), grander stucco-fronted and Regency-era housing near Regent's Park and Primrose Hill, and everything in between. The right loft conversion depends heavily on the roof type, so we start with what your specific property can actually support.
Conservation areas are widespread — Camden Town, Primrose Hill and the Regent's Park areas all carry tight controls, and Primrose Hill in particular has many sensitive and listed buildings. Street-facing roof changes are scrutinised, so rear dormers and sympathetic mansards are usually the workable routes.
On the standard Kentish Town Victorian terrace, an L-shaped dormer over the back addition is the workhorse conversion — a double bedroom and en-suite without touching the street elevation. We confirm the planning route and party wall position before any work is priced.
Camden loft costs vary widely with the housing type and conservation sensitivity; expect figures above the outer-London average. Typical ranges:
| Project type | Typical cost | Timeline |
|---|---|---|
| Rear dormer conversion | £47,000 – £63,000 | 8–12 weeks |
| L-shaped dormer (common in NW5) | £57,000 – £80,000 | 10–14 weeks |
| Mansard conversion | £68,000 – £100,000 | 12–18 weeks |
| Heritage / conservation-led conversion | from £80,000 | 14–20 weeks |

On the typical NW5 Victorian terrace, an L-shaped dormer over the rear back addition gives the most usable space — usually a double bedroom plus en-suite — without altering the street-facing roof. We assess the roof and head height at the free site visit.
Yes, in much of the borough. The Camden Town, Primrose Hill and Regent's Park conservation areas restrict street-facing changes, and Primrose Hill has many listed buildings. We design to the local policy and manage the application.
Often, but it's a heritage-led job — and if the property is listed it needs listed building consent. We work sensitively with original fabric and coordinate the consents and drawings before starting.
Most of the work happens above your living space with access via scaffolding, so you can usually stay in the house. We protect the existing rooms and staircase, and keep one team on site from start to finish.
