Frequently Asked Questions — Stratford
What does a premium extension cost in Stratford, E15?
The cost of an extension in Stratford depends on its size, the specification and the structural work involved. Our London cost guide puts a single-storey rear extension at £80,000–£110,000 at mid specification and £120,000–£160,000 at high specification, and a double-storey rear extension at £170,000–£230,000 and £240,000–£320,000. Build rates run from £2,500–£3,200/m² at mid-range specification to £3,200–£4,500/m² at high specification. Alstruct provides a fixed, itemised quotation after a site visit; our house extension cost guide explains what moves the price.
Is planning permission required for extensions near the Olympic Park?
Properties near the Queen Elizabeth Olympic Park may fall within the Legacy Corporation planning authority area rather than Newham Council. Alstruct identifies the correct planning authority for your property and manages all applications. Many standard extensions still qualify under Permitted Development rights, but proximity to the Olympic Park may bring additional design considerations.
Can Alstruct renovate both Victorian and modern properties in Stratford?
Absolutely. Stratford's unique mix of characterful Victorian terraces and contemporary developments requires versatile expertise. Our team excels at period property renovation, sympathetically restoring original features while introducing luxury modern amenities. We are equally accomplished with modern properties, delivering bespoke interior fit-outs, premium extensions and sophisticated design upgrades.
How has Stratford's regeneration affected property investment?
Stratford's transformation since the 2012 Olympics has made it one of London's most exciting investment locations. High-quality extensions and renovations deliver exceptional returns in E15, with premium rear extensions adding 15-25% to property values. Alstruct helps homeowners maximise their investment with bespoke designs that appeal to Stratford's increasingly affluent market.

Learn more →House and kitchen extensions in Stratford
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.
Newham Council permits most single-storey extensions under permitted development; conservation areas include the Woodgrange Estate in Forest Gate. 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 Keogh Road 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.
