Your Local Home Extension
Specialists in Bayswater
Looking for home extension builders in Bayswater (W2)? Buildaway works across the W2
postcode - the stucco terraces around Westbourne Grove and Craven Hill, the mansion
blocks off Queensway and Porchester Gardens, and the period homes near Lancaster
Gate, Whiteleys and Hyde Park.
Home extension in Bayswater usually means rear or lower-ground work, and both meet
conservation constraints in W2. Buildaway handles design, planning and build
together, because a scheme drawn without the planning position is a scheme that
stalls. Our Bayswater extension team resolves party-wall notices, underpinning where
required, drainage and structure before breaking ground - then delivers the shell
and the finish on one contract, with the full extension cost agreed in writing up
front.

What Our Clients Say
Real reviews from our satisfied customers.
“I was recommended Buildaway by a colleague as I was impressed by the work they had done for my colleague. From the moment I contacted Cormac, I knew I was in good hands. He was incredibly friendly and accommodating right from the start. The very next day, he was at my property, taking measurements and discussing design options. What really impressed me was Cormac's honesty…”
Nana A.
“The quality of the work, their high standards, and their professionalism, along with effective and proactive communication made a refreshing change from the builders I have used in the past. Even when we changed our minds and ideas during the job Cormac’s patience and support emphasised that he wanted to make sure that the finished product was exactly what we wanted…”
Michael Marks
“From scoping to completion, Cormac was always very responsive, answering any questions we had on product selection and helped us source the products to get the best price. His team worked extremely hard and a big shoutout to Greg for his attention to detail! We couldn’t be happier with the results and would highly recommend Buildaway for any building project in the future…”
Georgina Ehmcke
“From my first contact with Cormac, I was in good hands. His team turned my vision into reality, communicating with me every step of the way and offered helpful suggestions which turned my bathroom into an oasis. I could not be happier and would highly recommend their services. Thank you to the team of Buildaway Construction Ltd…”
Jackie Brown
“They were also very professional day to day - always tidy, and cleaned up really thoroughly when taking away all rubbish at the end. They stuck to the agreed timelines, and pricing was transparent throughout, with clear communication on any issues as they arose. Overall, I’m really pleased with the result and felt I could trust them throughout. I wouldn’t hesitate to recommend them…”
Sean Kelleher
“It was an absolute pleasure working with Cormac and the Buildaway team. Greg is an absolute star. Cormac’s communication and advice was excellent, and the organisation and sourcing of additional materials was brilliant. A truly great team, I would thoroughly recommend Buildaway if you are after a stress free and top quality renovation.”

Frequently Asked Questions
Your questions about home extensions in Bayswater, answered.
How much does a home extension cost in Bayswater?
Most Bayswater extensions land between £40,000–£60,000 and £60,000–£80,000, with double-storey schemes around Queensway and Westbourne Grove reaching £100,000+. What people underestimate in W2 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 Bayswater?
Twelve to twenty weeks on site for Bayswater, scheme depending. The build is the predictable part; Westminster City Council determination and party-wall awards are what stretch W2 projects. Buildaway handles both alongside design so the dates hold.
Do I need planning permission for an extension in Bayswater?
Sometimes yes, sometimes no. In Bayswater, permitted development can cover a modest rear extension, but Westminster City Council takes a close view on anything altering the street elevation, and heritage designation around Queensway and Westbourne Grove removes the easy route. Buildaway checks planning, party-wall and freeholder position together.
What types of extension do you offer in Bayswater?
We handle single-storey, side-return, wrap-around, double-storey and basement extensions throughout Bayswater. 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 Bayswater extensions?
We do the whole thing. Buildaway surveys your Bayswater 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 Queensway and Westbourne Grove to sign-off.
Are your extension specialists local to Bayswater?
Yes. Buildaway works across Bayswater and the surrounding W2 streets regularly, so we know the plots around Queensway and Westbourne Grove, the drainage runs, and what Westminster City Council has approved nearby. Local precedent is genuinely useful - knowing what got consented on the next street shapes a scheme that will pass.
