Many Hackney streets fall under Article 4 Directions, which remove Permitted Development rights, so a full application to London Borough of Hackney is often needed even for modest rear extensions. We check your specific address free of charge before any design work begins for you.

Hackney properties suit single-storey rear extensions, double-storey additions, side returns, loft conversions, and wraparound extensions. The dominant stock across E8, E5 is Victorian and Georgian terraces, which responds well to these approaches. We advise on the right option for your home and budget free of charge.

An Article 4 Direction removes Permitted Development rights on specific streets, so works that would normally be automatic instead need a full application to London Borough of Hackney. This adds time but not complexity. We confirm whether your address is affected free of charge.

London Borough of Hackney targets 8 weeks for householder applications from validation. Conservation area or more complex cases can take up to 13 weeks. Once granted, permission stays valid for 3 years. We track every application closely and respond to any council queries immediately on your behalf.

Extension Architecture has completed 40+ projects across E8, E5, N16 and the wider Hackney area. We are RIBA-chartered, ARB-registered, carry an in-house structural engineer, and hold a 98% planning approval rate.
