Specialists in Notting Hill
Looking for home extension builders in Notting Hill (W11)? Buildaway extends homes
across W11 - the stucco terraces on Elgin Crescent and Kensington Park Road, the
houses off Portobello Road and Westbourne Grove, and the properties toward Ladbroke
Grove, Golborne Road, Notting Hill Gate and Holland Park.
Extending a Notting Hill terrace means satisfying conservation officers and
neighbours alike, and Buildaway handles both alongside the structure. In W11 the
work is usually a lower-ground excavation or a rear infill, where underpinning,
waterproofing and party-wall awards drive the programme. Buildaway settles the
planning position and the notices before breaking ground, then delivers structure,
services and finish on one W11 contract.

What Our Clients Say
Real reviews from our satisfied customers.
“The team turned up when they said they would and kept the house tidy each day, which made a big difference while we were living in the property during the works. The quality of the finish is excellent. The bathroom looks fantastic and the bedrooms feel completely refreshed. We wouldn’t hesitate to recommend Cormac and the Buildaway team…”

“A great transformation of my bathroom into something modern and sleek. Cormac was professional to work with from the start and was very helpful in taking my ideas and sourcing products to fit the space and look aesthetically pleasing.

Jackie Brown
“Greg's attention to detail and dedication elevated both the experience and the result - he certainly knows his way around a tile. In addition to the bathroom refit, Cormac replaced all the plastic switches, sockets and pull-cords in the house with brushed brass. Highly recommended and will certainly work with the Buildaway team again…”
Kane Dempsey
“We’ve had a genuinely fantastic experience with Buildaway. Cormac was ultra responsive and excellent at communicating with us throughout our project. The quality of the work was excellent - so much so, that we extended our project by adding a range of other building renovations to our original ask, each completed with care and precision…”

Frequently Asked Questions
Your questions about home extensions in Notting Hill, answered.
How much does a home extension cost in Notting Hill?
Most Notting Hill extensions land between £3,200–£4,300 and £4,300–£5,700, with double-storey schemes around Portobello Road and Elgin Crescent reaching £80,000–£107,500. What people underestimate in W11 is below ground: foundations, drainage diversions and party-wall works are real cost before anything is visible. Buildaway prices them in, not after.
How long does a home extension take in Notting Hill?
Allow roughly 12–20 weeks of build in Notting Hill, depending on scheme. The programme most people forget is before that: design, the Royal Borough of Kensington & Chelsea approval and party-wall awards can add 3–4 months to a W11 project. Buildaway runs those in parallel and gives you a realistic combined timeline up front.
Do I need planning permission for an extension in Notting Hill?
Many Notting Hill single-storey rear extensions fall under permitted development, subject to depth, height and materials limits. But conservation-area designation around Portobello Road and Elgin Crescent and listed status remove those rights, making the Royal Borough of Kensington & Chelsea approval essential - and flats in W11 have no permitted development rights at all. Buildaway establishes your position before design.
What types of extension do you offer in Notting Hill?
Rear, side-return, wrap-around, double-storey and lower-ground - Buildaway delivers all of them in Notting Hill. Terraces around Portobello Road and Elgin Crescent usually point to a side-return; where outward space is limited in W11, going down or reconfiguring inside often makes better sense. We advise from survey.
Do Buildaway handle both design and construction for Notting Hill extensions?
Both, on one contract. For Notting Hill clients Buildaway handles drawings, structural engineering, consents and construction. Splitting design from build is where W11 extension projects most often lose money, because the gap between them is nobody's problem until it is yours.
Are your extension specialists local to Notting Hill?
Yes. Buildaway works across Notting Hill and the surrounding W11 streets regularly, so we know the plots around Portobello Road and Elgin Crescent, the drainage runs, and what the Royal Borough of Kensington & Chelsea has approved nearby. Local precedent is genuinely useful - knowing what got consented on the next street shapes a scheme that will pass.
