Why Choose a House Extension in Camden?

Camden is one of London’s most desirable boroughs, with stunning period properties and a vibrant community. Property prices in Camden are among the highest in the capital, making a house extension in Camden a smart investment compared to the cost of moving. A well-designed extension can add substantial value to your home while creating the open-plan kitchen, extra bedroom, or home office your family needs. According to GOV.UK planning guidance, many extensions can be completed under permitted development rights.

Types of House Extensions We Build in Camden

Single-Storey Rear Extensions

Rear extensions are the most popular choice for a house extension in Camden. They extend your ground floor to create a spacious kitchen-diner, larger living area, or family room. Many single-storey extensions can be built under permitted development rights.

Side Return Extensions

Camden’s terraced homes often have a narrow side return that can be incorporated into the home. This is one of the most popular extensions in areas like Kentish Town and Camden Town, widening your kitchen without losing garden space.

Double-Storey Extensions

For maximum space, a double-storey extension adds rooms on two levels. Ideal for the larger properties in Hampstead and Belsize Park, this can provide a new kitchen downstairs and a bedroom or bathroom above.

Basement Extensions

Basement conversions and extensions are particularly popular in Camden, where space is at a premium. A basement can provide a cinema room, gym, home office, or additional bedroom with en-suite.

House Extension Camden – Planning Permission

Camden has extensive conservation areas, particularly around Hampstead and Primrose Hill, where planning permission requirements are stricter. Many smaller extensions can proceed under permitted development, but our team will assess your property and advise on all planning requirements. We have extensive experience working with Camden Council and can manage all applications on your behalf.

All house extensions must comply with building regulations for structural safety, foundations, drainage, insulation, fire safety, and ventilation. Fixiz Ltd handles the complete building control process.
