Quick answer
Builderr delivers garage conversions across Camden — NW1, NW3, NW5, WC1 and WC2 — £32,000–£85,000 typical. Camden's Victorian and Georgian stock has minimal integral-garage provision; most projects are mews-house garage-to-habitable conversions in Belsize Park, Primrose Hill, Hampstead and Bloomsbury, or coach-house outbuildings on the larger NW3 Hampstead plots. Build programmes 6–12 weeks. Mews conversions routinely need Listed Building Consent in addition to planning — Camden has 40+ conservation areas and a high concentration of statutorily-listed mews terraces.
Camden mews garage conversions almost always need LBC + planning in parallel (large share of mews stock is Grade II group-listed). Pre-application engagement is mandatory in conservation areas — pre-app fee £200–£500 saves months versus a refused application. Glazing replacements must match original cast-iron-framed garage doors where retained as historic fabric (Builderr specifies Crittall W20 or matching steel-frame replacements). Camden Basements SPD does not apply to garage conversions but affects any below-DPC excavation extensions.

Planning in Camden
Local planning rules for garage conversions in Camden.
Camden contains over 40 designated conservation areas including Gospel Oak, Hampstead, Primrose Hill and Regent's Park. The Camden Local Plan and individual Conservation Area Appraisals govern most residential alterations. Planning officers prefer mansard roof extensions over rear dormers in character areas and have refused many dormer applications. Basement conversions and additions require specialist supporting documentation. Pre-application consultation is highly recommended for any extension or roof addition.
Our planning team handles the full submission for Camden addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your garage conversion is permitted development, prior approval, or full planning before you sign anything.
