Ilford has Victorian and Edwardian terraces around Cranbrook Road and the Valentines area, and 1930s semis in Newbury Park, Gants Hill and Seven Kings. House extensions in Ilford are usually a rear extension on the terraces or a side and rear combination on the semis, creating a wide kitchen-family room; two-storey side extensions are common in Gants Hill.
Valentines Mansion Conservation Area covers the mansion and its park north of the town centre, and the Bungalow Estate in Seven Kings is also a conservation area; elsewhere national permitted development rights cover most single-storey rear extensions to houses. Most Ilford extensions we price fall between £2,500 and £4,000 per m², so a 25–30 m² kitchen extension is roughly £75,000–£120,000 fitted out; our house extension cost guide breaks the numbers down. We check permitted development rights at the first visit and deal with Redbridge Council in-house.

Loft conversions in Ilford
Hip-to-gable with a rear dormer suits the Ilford semis; the Edwardian terraces take a rear dormer with a bedroom and bathroom.
Expect £45,000–£75,000 for a dormer loft with a bedroom and en-suite, £60,000–£100,000+ for a mansard and from £25,000 for a Velux conversion; the loft conversion cost guide has the breakdown. For a Ilford loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.

Ilford renovations are typically whole-house modernisations: kitchens, bathrooms, rewiring, heating and layout changes.

Common questions about building in Ilford
Do I need planning permission for an extension in Ilford?
Usually not for a modest single-storey rear extension to a house. Houses (not flats or maisonettes) keep national permitted development rights for a single-storey rear extension of 3m attached or 4m detached, up to 6m or 8m through prior approval, and for most rear dormers within 40 cubic metres on a terrace or 50 on other houses. Ilford's conservation areas are Valentines Mansion, covering the mansion and its park north of the town centre, and the Bungalow Estate in Seven Kings, which also has an Article 4 direction. In those areas side extensions, two-storey rear extensions, cladding and roof additions need permission. Redbridge Council decides; see our permitted development guide.
What does Redbridge Council expect for loft conversions in Ilford?
Redbridge's Housing Design Guide SPD (2019) asks for rear dormers that stay subordinate to the roof: at least 0.5m below the ridge, 1m above the eaves, and set in 1m from the shared boundary and the roof edge (0.5m on a hipped roof). Hip-to-gable conversions will generally be refused where they are out of character or harm the symmetry of a pair of semis, and front and side dormers are generally not appropriate. These rules apply where a loft needs planning permission; many house lofts outside conservation areas are permitted development instead.
What does a side return extension cost in Ilford?
For Ilford's Victorian and Edwardian terraces, a side return extension costs £65,000–£130,000 at mid to high spec, including VAT; our side return extension cost guide shows how the figure is built up. A rear dormer loft is £45,000–£75,000 and an L-shaped dormer £55,000–£85,000, both including VAT. Where the extension needs planning permission, Redbridge's design guide sets a 3.5m rule-of-thumb depth for terraced and semi-detached houses.
