Specialists in East Dulwich
Looking for extension specialists in East Dulwich (SE22)? Buildaway extends homes
across SE22 - the Victorian terraces off Lordship Lane, North Cross Road and Barry
Road, the family houses around Goose Green and Dulwich Library, and the streets
toward Peckham Rye, Bellenden and East Dulwich station.
East Dulwich extension specialists know the Victorian side-return, and Buildaway
resolves structure, drainage and light before design is committed. In SE22 the side-
return infill is the classic scheme, and it lives or dies on the steel design, the
rainwater strategy and how much daylight actually reaches the middle of the plan.
Buildaway settles all three first, then delivers groundwork, structure, glazing and
finish on one contract.

Frequently Asked Questions
Your questions about home extensions in East Dulwich, answered.
How much does a home extension cost in East Dulwich?
As a guide, a home extension in East Dulwich (SE22) runs roughly £2,600–£3,500 for a single-storey rear, £3,500–£4,700 for a larger or wrap-around scheme, and £65,000–£87,500 for double-storey work. UK build costs sit around £1,800–£3,000 per m², and London consistently lands at the upper end. Buildaway fixes your figure in a written quote after survey.
How long does a home extension take in East Dulwich?
Allow roughly 12–20 weeks of build in East Dulwich, depending on scheme. The programme most people forget is before that: design, Southwark Council approval and party-wall awards can add 3–4 months to a SE22 project. Buildaway runs those in parallel and gives you a realistic combined timeline up front.
Do I need planning permission for an extension in East Dulwich?
Many East Dulwich single-storey rear extensions fall under permitted development, subject to depth, height and materials limits. But conservation-area designation around Lordship Lane and Goose Green and listed status remove those rights, making Southwark Council approval essential - and flats in SE22 have no permitted development rights at all. Buildaway establishes your position before design.
What types of extension do you offer in East Dulwich?
Buildaway builds rear, side-return, wrap-around, double-storey and lower-ground extensions across East Dulwich. Which suits your SE22 home depends on the plot, the boundary and what Southwark Council will accept. Around Lordship Lane and Goose Green the side-return infill is often the highest-value option. Buildaway surveys before recommending.
Do Buildaway handle both design and construction for East Dulwich extensions?
Yes. Buildaway takes East Dulwich extensions from feasibility and design through Southwark Council application, party-wall notices, Building Control, groundwork, structure and finish. One contract across every SE22 project, so the design intent and the build are the same team's responsibility.
Are your extension specialists local to East Dulwich?
Yes, East Dulwich is core Buildaway territory. We build extensions across SE22 regularly and understand both the buildings and the Southwark Council policies that govern them.
