House Extensions in Hackney: Stoke Newington, Dalston and E5/E8/N16 Expert Guide 2026

Looking to extend your Hackney home? House extensions are transforming properties across Stoke Newington, Dalston, Clapton, and surrounding E and N16 postcode areas. This comprehensive guide covers everything homeowners need to know about house extensions in Hackney.

Why Choose a House Extension in Hackney?

Hackney’s Victorian and Edwardian terraces offer excellent extension potential. With the borough experiencing significant regeneration and property value growth, extending your home is a smart investment that adds both space and value.

Planning Permission and Conservation Areas

Hackney has numerous conservation areas, particularly around Stoke Newington and De Beauvoir. Key considerations include:

  • Many extensions fall under Permitted Development rights
  • Conservation areas have stricter design requirements
  • Article 4 directions apply in some locations
  • Rear extensions are generally more straightforward

Always check with Hackney Council before starting work.

Types of House Extensions

Popular extension types in Hackney include:

Single-storey rear extensions

Ideal for creating larger kitchen-diners that open onto the garden.

Side return infill extensions

Make use of the narrow alley typical of Victorian terraces, adding valuable width to existing rooms.

Double-storey rear extensions

Provide extra bedrooms or bathrooms upstairs as well as more living space on the ground floor.

Loft and rear combination projects

Maximise every part of the house, often creating multi-level family homes without moving.
