Paddington W2 extension builders handling rear, side and lower-ground schemes, with Buildaway accountable for consents, structure and finish.
Your Local Home Extension
Specialists in Paddington
Need home extension builders in Paddington (W2)? Buildaway extends homes across W2 -
the terraces on Sussex Gardens, Norfolk Square and Westbourne Terrace, the houses
off Praed Street, and the properties near Paddington Basin, Little Venice, Lancaster
Gate and Hyde Park.
Paddington extension builders handle rear, side and lower-ground schemes, with
Buildaway accountable for consents, structure and finish. W2's conservation-area
terraces limit what can be added above ground, so the space is frequently won below
- which puts underpinning, drainage and waterproofing at the centre of the job.
Buildaway's Paddington team resolves the engineering and the approvals first, then
builds it out on one clearly priced contract.

Frequently Asked Questions
Your questions about home extensions in Paddington, answered.
How much does a home extension cost in Paddington?
Buildaway prices Paddington extensions from survey. As a working guide across W2: £40,000–£60,000 single-storey rear, £60,000–£80,000 wrap-around, £100,000+ double-storey. Roof lanterns, bifolds and structural spans move it most. The quote is fixed in writing before we break ground.
How long does a home extension take in Paddington?
Allow roughly 12–20 weeks of build in Paddington, depending on scheme. The programme most people forget is before that: design, Westminster City Council approval and party-wall awards can add 3–4 months to a W2 project. Buildaway runs those in parallel and gives you a realistic combined timeline up front.
Do I need planning permission for an extension in Paddington?
Many Paddington single-storey rear extensions fall under permitted development, subject to depth, height and materials limits. But conservation-area designation around Sussex Gardens and Paddington Basin and listed status remove those rights, making Westminster City Council approval essential - and flats in W2 have no permitted development rights at all. Buildaway establishes your position before design.
What types of extension do you offer in Paddington?
We handle single-storey, side-return, wrap-around, double-storey and basement extensions throughout Paddington. The right answer for your W2 property depends on drainage, boundary and Westminster City Council policy. Buildaway establishes those before proposing anything.
Do Buildaway handle both design and construction for Paddington extensions?
We do the whole thing. Buildaway surveys your Paddington property, designs a scheme that is genuinely consentable, secures approval from Westminster City Council, and builds it with our own team - one point of contact from feasibility around Sussex Gardens and Paddington Basin to sign-off.
Are your extension specialists local to Paddington?
Yes, Paddington is core Buildaway territory. We build extensions across W2 regularly and understand both the buildings and the Westminster City Council policies that govern them.
