Real reviews from our satisfied customers.
"We recently used Buildaway for a full bathroom renovation at our home in Orpington, along with plastering, redecoration of both bedrooms and new spotlights installed in the bedrooms. From start to finish the experience was smooth and well organised. Cormac was easy to deal with, communication was clear and everything ran to the agreed timelines. 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."
Helen Sivyer
"We had an excellent experience working with Buildaway. Cormac was incredibly easy to work with, and gave helpful advice. The finished job was neat, professional and completed efficiently. We'd definitely recommend and would use them again!"
Roisin Lawrence
"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. Cormac and his team clearly take a lot of pride in the service they offer - from a really helpful initial visit and quotation, to the high quality work delivered - they even thoroughly cleaned all our rooms and touched up any marks. We would highly recommend them to anyone considering getting work done. Friendly, reliable and also competitive. Thanks for all your help."
Kiran Collier
"Cormac & his team were brilliant throughout our bathroom renovation project. 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
"It was a pleasure working with the Buildaway team to reimagine a tired old bathroom into the most attractive room in the house in just two weeks. Cormac's enthusiasm, communication, and project management are top-notch - he went above and beyond on more than one occasion. 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
"I posted a bathroom job on a Bark App and within ten minutes I got a notification that I had about 5 responses. I spoke to Cormac of Buildaway first, explained my plans a bit and he asked where I was and when I told him, he said I am not far, I will come and view the place. In half an hour he was at the door and from his introduction in my mind I said I think he will do the job. He came in, I showed him and detailed my proposal, he listened and then checked, measured and said to me it is doable and will get back to me with a quotation detailing the scope of work. Indeed he delivered as promised, we discussed thoroughly in detail, checking everything, gave me ideas as well as listening to me. We agreed on a plan and he delivered. Any issues or worries I may have had, he was always available to explain and reassured me. Cormac is very good with communication, listening, advising, a hard worker and an excellent team/project leader. He has been transparent and I would not fault him in his deliverance of what he promised to do. I am extremely impressed, happy and proud of what he and his team of Archie, Ben and Danny delivered. They all went beyond and far, I am very grateful for what they have done for me. I would 100% recommend Buildaway for any building, renovation etc - an excellent team with a good rapport, team spirit and working harmoniously together. Thank you Team Buildaway. Thank you Cormac, you are a star. 👍"

Frequently Asked Questions
Your questions about home extensions in Leyton, answered.
How much does a home extension cost in Leyton?
Home extension cost in Leyton generally ranges from £40,000 to £100,000+. A single-storey rear extension (3m x 4m) typically costs £40,000–£60,000, larger single-storey extensions (5m x 6m) run £60,000–£80,000, side returns £30,000–£50,000, and double-storey extensions £80,000–£100,000+. The home extension cost Leyton varies based on groundworks, finishes, room type, and structural alterations required. Buildaway provides full, itemised cost breakdowns upfront so you know exactly what you're paying for before work starts.
How does home extension cost in Leyton compare to the UK average?
Home extension cost in Leyton typically runs 15–20% above the UK national average, reflecting East London labour rates and material costs. While a single-storey rear extension averages £35,000–£50,000 nationally, a comparable home extension in Leyton realistically sits at £40,000–£60,000. The E10 and E11 postcodes sit at the higher end of home extension cost UK figures for the region. Buildaway offers transparent, no-hidden-fee estimates so you can budget with confidence.
How long does a home extension in Leyton take?
Most home extensions in Leyton complete within 12 to 20 weeks from groundworks to handover. Single-storey rear extensions take 12–14 weeks, side returns around 10–12 weeks, and double-storey extensions 16–20 weeks. Timelines depend on planning permission duration, groundworks complexity, and Building Control inspection stages. Where party wall agreements are required - common with Leyton's terraced street patterns - additional lead time should be anticipated. Buildaway sets realistic schedules from the outset and keeps you updated throughout.
