Quick answer
Builderr delivers side return and rear kitchen extensions across Hackney — E5, E8, E9, N1 and N16. Typical Hackney kitchen extension cost £55,000–£140,000 over 10–16 weeks including fitted kitchen. The Victorian terraces of Dalston, London Fields, Stoke Newington and De Beauvoir suit 1.3–1.7m side-return infill + 3.5–4m rear extension with structural rooflight and Crittall W20 internal screen between kitchen and reception. London-stock brick matching the original soft-red is critical — Petersfield Imperial or York Handmade are typical; modern wirecut brick is routinely refused on character streets. Natural slate or zinc standing-seam roof, lead-clad parapet detail, and slim-frame steel rather than bulk aluminium are the Hackney CA standards. Article 4 directions across most of E8, N16 and N1 mean nearly every external alteration needs full planning — De Beauvoir, London Fields, Clapton, Mapledene, Stoke Newington and Albion Square CAs each impose specific material codes. Determination typically 10–12 weeks; pre-app advice (£175–£450) on conservation streets shortens that.
Hackney officers reject UPVC sash replacement universally and prefer Crittall W20 (true steel) over W30 aluminium-look on internal broken-plan screens. Lime-mortar repointing of exposed brickwork required NHL 3.5. Party Wall awards £900–£1,500 per neighbour; side-return + rear combination typically 2 awards. CIL Hackney £125/m² Zone B (most residential streets).

Planning in Hackney
Local planning rules for kitchen extensions in Hackney.
Hackney's conservation areas include De Beauvoir, Clapton, Stoke Newington, Victoria Park, Hackney Central and Dalston. Article 4 directions cover wide residential zones in E8, E9 and N16, removing permitted development rights for most external alterations. The council is open to sensitive contemporary design but insists on matching materials and requires Design and Access Statements for most applications. Mansards are preferred over rear dormers in conservation-protected streets.
Our planning team handles the full submission for Hackney addresses including drawings, Design and Access Statements where required, and pre-application consultation with the council. We tell you whether your kitchen extension is permitted development, prior approval, or full planning before you sign anything.
