What Our Clients Say
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
"Exceptional Bathroom Refurbishment and More! 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. He was upfront about what would and wouldn't work with my space, which was quite tight. I was a bit indecisive, changing my mind several times, but Cormac remained patient and helped me design and choose materials for my dream bathroom. Communication was exceptional throughout the entire project. I didn't have to worry about a thing, as Cormac and his team effectively project-managed everything, which was a huge relief since I was mostly away during the project. They were on-time every day and completed the job in the agreed-upon two weeks. The team was respectful of my space and left everything clean after completing the project. I can't thank them enough! I highly recommend Cormac and the Buildaway team for bathroom refurbishments and all other building work. They are more than competent and reliable; you'll be getting the best of the best. Cormac even provided advice and recommendations for other projects in my house. Don't hesitate to book Buildaway for your bathroom refurbs or other building projects - you won't regret it!"

"I wanted a bathroom refurbishment done and after meeting with several tradesmen decided to go with Buildaway Construction Ltd. 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
"Buildaway recently finished a two week job completely renovating my bathroom and part renovation of the downstairs toilet. Cormac and his team did an incredible job. 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. From ordering products, to suggestions and ideas Cormac was helpful and a pleasure to work with. I would without question use Buildaway again for other work and would have no hesitation in recommending them to friends and family."
Michael Marks
"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
"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 loft conversions in Chelsea, answered.
Do I need planning permission for a loft conversion in Chelsea?
Many loft conversions in Chelsea require full planning permission rather than relying on permitted development rights, particularly for properties within the Royal Borough of Kensington and Chelsea's conservation areas, which cover a significant portion of SW3 and SW10. Even where permitted development rights technically apply, any property within a conservation area is subject to stricter controls on roof alterations, materials, and external appearance. Buildaway carries out a thorough planning feasibility assessment on every Chelsea project and handles all planning applications and building regulation submissions on your behalf, so you are never left navigating this alone.
How much does a loft conversion cost in Chelsea?
Loft conversion costs in Chelsea typically range from £40,000 to £75,000 or more depending on the conversion type, specification, and any planning or structural complexities involved. A velux conversion starts from around £40,000–£50,000, dormer loft conversions generally range from £50,000–£65,000, and premium mansard conversions on Chelsea period terraces can exceed £70,000 depending on the extent of the structural works and finishes required. Buildaway provides free, detailed fixed-price quotes so you know your exact loft conversion cost in Chelsea before any work is agreed or materials are ordered.
What types of loft conversion are available in Chelsea?
Buildaway offers all principal loft conversion types across Chelsea including velux conversions (roof windows with minimal structural intervention), dormer loft conversions (traditional box dormers adding significant headroom and usable floor area), hip-to-gable conversions (suited to period semis where the hip end can be converted to a full gable), and mansard conversions (the premium option with near-vertical rear walls delivering maximum internal space). Our loft conversion specialists in Chelsea assess each property individually and recommend the most appropriate conversion type based on your planning position, roof structure, budget, and loft conversion ideas.
How long does a loft conversion take in Chelsea?
Most loft conversions in Chelsea take between 7–12 weeks from the start of on-site works. A velux conversion typically takes 6–8 weeks, a dormer loft conversion 8–10 weeks, and a hip-to-gable or mansard conversion 10–13 weeks due to the more extensive structural works involved. Where a planning application is required which is common across Chelsea's conservation areas the pre-construction phase adds a further 8–10 weeks. Buildaway provides a detailed project timeline at your consultation so you can plan around the programme with complete confidence.

Yes. Buildaway loft conversion specialists serve Chelsea and the surrounding SW postcodes including SW3, SW10, and SW6.

Is a loft conversion a worthwhile investment in Chelsea?
For the vast majority of Chelsea homeowners, yes. Property values in SW3 and the wider Chelsea area remain among the highest in London, and the premium attached to an additional bedroom particularly with an en-suite is substantial. A well-specified loft conversion in Chelsea typically adds 15–20% to the value of the property, and on higher-value Chelsea terraces and townhouses, the uplift in absolute terms frequently exceeds the total build cost by a significant margin. Buildaway can advise on which conversion type is most likely to maximise the return on your specific property at your initial consultation.
