Stratford is Victorian terraces around Maryland, Forest Gate and West Ham, Edwardian houses towards Leytonstone, and new-build apartments across the Olympic Park and Stratford City. Rear and side-return kitchen extensions on the Victorian terraces are the standard Stratford project; the wider Forest Gate houses take a wraparound.
National permitted development rights cover most single-storey rear extensions to houses; Stratford's conservation areas include Stratford St John's, University and Sugar House Lane. Most Stratford 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 Newham Council in-house.

Loft conversions in Stratford
Stratford's Victorian terraces suit rear dormers and L-shaped dormers, as at our Stratford Twin Terraces project where two adjacent terraces gained zinc-clad loft conversions.
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 Stratford loft we measure head height, roof structure and the stair landing first, and the quote includes structural calculations and Building Regulations approval.
Renovations and refurbishment in Stratford
Stratford renovations are usually complete refurbishments of Victorian terraces: structural openings, rewiring, new kitchens and bathrooms. Typical Stratford refurbishments include structural openings with steel beams, new kitchens and bathrooms, rewiring, heating and period repairs such as sash windows, cornices and floors. See our renovation cost guide for realistic budgets. Stratford projects are run by a single project manager under a JCT contract, with a written specification and a 10-year workmanship warranty.

Common questions about building in Stratford
Do I need planning permission for an extension in Stratford?
Not for every project. 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. Stratford's conservation areas are Stratford St John's, University, Sugar House Lane and Three Mills; in them, side extensions, two-storey rear extensions, cladding and roof additions need permission. Since 1 December 2024 every planning application in Stratford, including the former Legacy Corporation area around the Olympic Park, goes to Newham Council. See our permitted development guide.
What does Newham Council expect for loft conversions in Stratford?
Newham's Altering and Extending your Home SPD, adopted in February 2018, applies across the borough, including the Olympic Park area. It asks for extensions that are subservient to the original house, with clear set-backs and matching roof pitches where practicable. Street-facing roof slopes, ridge lines and chimneys should be kept, which in practice points lofts on Stratford's terraces towards rear dormers. Any extension must also protect neighbours' daylight, privacy and outlook.
What does a loft conversion cost in Stratford?
On Stratford's Victorian terraces, a rear dormer loft costs £45,000–£75,000 and an L-shaped dormer over the back addition £55,000–£85,000, both including VAT; our dormer loft conversion cost guide sets out what each includes. At ground floor level, a Victorian side return extension is £65,000–£130,000 at mid to high spec, including VAT. The roof structure, head height and stair position decide which loft fits.
