Why Choose a House Extension in Hackney?

Hackney is one of East London’s most vibrant and rapidly transforming boroughs, with a mix of Victorian terraces, Georgian townhouses, and modern developments. With demand for property in Hackney at an all-time high and moving costs continuing to rise, a house extension is the smartest way to gain the space you need without leaving the area you love. A well-planned extension in Hackney can significantly increase your property value while enhancing your daily living.

Types of House Extension Hackney Homeowners Choose

Single-Storey Rear Extensions

The most popular type of house extension in Hackney. A rear extension can create a spacious open-plan kitchen-diner, a larger living area, or a dedicated family room. Many single-storey rear extensions up to 6 metres for semi-detached or 8 metres for detached properties can be built under permitted development.

Double-Storey Extensions

Double-storey extensions provide additional space on both floors, typically adding a kitchen-diner below and an extra bedroom or bathroom above. This maximises the value added to your property and is ideal for growing families in areas like Stoke Newington and Homerton.

Side Return Extensions

Side return extensions make use of the narrow alley that runs alongside many terraced and semi-detached properties. By incorporating this unused space, you can significantly widen your kitchen or living area without losing garden space.

Wrap-Around Extensions

A wrap-around extension combines a side and rear extension into one, creating the maximum amount of additional ground floor space. This is an excellent choice for homeowners wanting a large open-plan kitchen, dining, and living area.

Planning Permission for House Extension in Hackney

Many extensions in Hackney can be built under permitted development rights without requiring planning permission. However, the size, height, and position of the extension must comply with specific rules. Hackney has numerous conservation areas — including Stoke Newington Church Street, De Beauvoir, and Dalston — where stricter planning controls apply. Our team will assess your property and advise on all planning requirements from the start.

All extensions must comply with building regulations covering foundations, structural integrity, damp proofing, drainage, insulation, and fire safety. Fixiz Ltd manages the complete building control process on your behalf.
