Wanstead is Victorian and Edwardian houses around the High Street and Wanstead Park, 1930s semis and detached homes towards Aldersbrook and Snaresbrook, and Georgian houses on the Green. Rear and side extensions on the semis and wraparounds on the Edwardian houses are the typical Wanstead projects; Aldersbrook's wide houses take a full-width kitchen-family room.
Budget guidance for Wanstead: 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). Wanstead Village, Wanstead Grove, Wanstead Park and Aldersbrook are conservation areas, with Article 4 directions on the Aldersbrook and Lake House estate and on 1 to 47 Spratt Hall Road; elsewhere national permitted development rights cover most single-storey rear extensions to houses. Where approval from Redbridge Council is needed, our design team prepares and submits the application.

Loft conversions in Wanstead
Wanstead's roofs suit hip-to-gable conversions on the semis and rear dormers on the Edwardian houses, usually delivering a master suite.
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 Wanstead 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 Wanstead
Wanstead renovations are whole-house refurbishments of Edwardian and interwar homes, often with an extension and a new open-plan ground floor. Typical Wanstead 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 Wanstead, as everywhere, we work to a JCT contract, a written specification and a 10-year workmanship warranty.

Common questions about building in Wanstead
Do I need planning permission for an extension in Wanstead?
Often, because much of Wanstead is protected. 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 most rear dormers within 40 or 50 cubic metres. Wanstead Village, Wanstead Grove, Wanstead Park and the Aldersbrook and Lake House Estate are conservation areas, where side extensions, two-storey rear extensions, cladding and roof additions need permission. Article 4 directions go further on Aldersbrook (front, side and rear elevations, porches, solar panels and roof alterations) and on 1–47 Spratt Hall Road. Redbridge Council decides; see our permitted development guide.
What does Redbridge Council expect for basements in Wanstead?
Redbridge's Housing Design Guide SPD (2019), read with Local Plan policy LP31, limits basements to a single storey under no more than 50% of the rear garden or 30% of the front garden. Any part under a garden needs 1m of permeable soil above it, and a Basement Impact Assessment is required with the application. On the Aldersbrook and Lake House Estate, the estate's own conservation area design guide and the 2020 Article 4 direction apply as well.
What does a side return extension cost in Wanstead?
For Wanstead'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 what is included. A rear dormer loft is £45,000–£75,000 and an L-shaped dormer £55,000–£85,000, both including VAT. The final figure depends on the length of the return, the glazing and the kitchen you choose.
