Hackney is Victorian terraces from London Fields and Dalston to Victoria Park and Homerton, Georgian houses in Clapton and around Hackney Downs, and warehouse conversions near the canal. Rear and side-return kitchen extensions with large glazing are the typical Hackney project, plus basement conversions on the taller Georgian and Victorian houses.
Budget guidance for Hackney: expect £2,500–£4,000 per m² for a single-storey extension, which puts a 25–30 m² kitchen extension at £75,000–£120,000; two-storey and wraparound schemes are priced on the structure involved (see our house extension cost guide). Hackney has 35 conservation areas, including Clapton Square, Victoria Park and Broadway Market, so permitted development rights vary street by street. Where approval from Hackney Council is needed, our design team, working with your architect or ours, prepares and submits the application.

Loft conversions in Hackney
Hackney's Victorian terraces take rear dormers and L-shaped dormers; Hackney Council's guidance resists front dormers, and in conservation areas roof extensions on an unaltered roofline are not generally accepted.
Typical London figures are £25,000–£45,000 for a Velux conversion, £45,000–£75,000 for a dormer and £60,000–£100,000+ for a mansard (details in our loft conversion cost guide). Every Hackney loft quote follows a measured survey of the roof, head height and stair position, and includes Building Regulations sign-off, fire doors and structural calculations.
Renovations and refurbishment in Hackney
Hackney renovations are often complete refurbishments of Victorian houses and flat conversions, including structural openings, rewiring and new bathrooms. Typical Hackney refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. Budgets are set out in our renovation cost guide; in Hackney, as everywhere, we work to a JCT contract, a written specification and a 10-year workmanship warranty.

Common questions about building in Hackney
Do I need planning permission for an extension in Hackney?
Houses, but not flats or maisonettes, keep national permitted development rights for a single-storey rear extension of 3m attached or 4m detached, or 6m and 8m through prior approval, and most rear dormers within 40 or 50 cubic metres. Hackney Council has 35 conservation areas, including Clapton Square, Mare Street, Victoria Park, Broadway Market, De Beauvoir and Well Street. Single-storey rear rights remain in them, but side extensions, two-storey rear extensions, cladding and roof additions need permission. Article 4 directions go further on mapped properties in De Beauvoir and St Mark's, and in the Well Street, Brownswood, Beck Road and Shacklewell Green areas they remove most householder rights.
What does Hackney Council expect for loft conversions in Hackney?
Hackney's Residential Extensions and Alterations SPD, adopted in December 2025, sets the rules. Front dormers are not normally acceptable. Rear dormers are normally acceptable if they sit at least 0.5m below the ridge and 0.5m in from the roof edges, at least 1m above the eaves, and take up no more than half the width and height of the roof. In conservation areas, roof extensions on an unaltered roofline are not generally acceptable, so we check the neighbouring roofs before drawing anything.
What does a side return extension cost in Hackney?
Hackney's Victorian terraces, from London Fields to Victoria Park, suit side return extensions, which typically cost £65,000–£130,000 at mid to high specification, including VAT. The length of the infill, the glazing and the kitchen drive the figure. Our Victorian side return extension cost guide breaks it down. Under Hackney's 2025 SPD, single-storey rear extensions should keep at least half of the original garden.
