Looking to extend your Camden home? House extensions are an excellent way to add space and value to properties in Hampstead, Kentish Town, Camden Town, and surrounding NW postcode areas. This comprehensive guide covers everything homeowners need to know about house extensions in Camden.
Why Choose a House Extension in Camden?
Camden properties, from Victorian terraces in Kentish Town to period homes in Hampstead, offer significant extension potential. With Camden being one of London’s most desirable boroughs, extending rather than moving makes excellent financial sense.
Planning Permission and Conservation Areas
Camden has extensive conservation areas, particularly in Hampstead and Belsize Park. Key considerations include:
- Many extensions fall under Permitted Development rights
- Conservation areas have stricter requirements
- Listed buildings need Listed Building Consent
- Basement extensions often require planning permission
Always check with Camden Council before starting work.
Types of House Extensions
Popular extension types in Camden include:
Basement extensions in Camden
Popular in Hampstead and Belsize Park where garden space is limited but property values justify the investment.
Single-storey rear extensions
Ideal for creating open-plan kitchen-diners that connect to the garden.
Side return extensions
Perfect for Victorian terraces in Kentish Town and Camden Town, making use of the narrow alley alongside the property.
Roof extensions and dormers
Adding valuable extra bedrooms or bathrooms by converting unused loft space.
