I had a commercial property converted into 2 one bedroom flats. Akam builders did an A-class job. The work was done to a very high standard and within the time scale stated by Gurwinder. I was impressed by the extra work he did without any extra charge. This builder is a genuine and reliable builder. The work is in perfect condition after 6 months.

Hi, I’m Jon, the Founder of W8 Build. With over three decades of experience in both modern and listed buildings, I’ve dedicated my career to transforming spaces – from bespoke home extensions and loft conversions to the careful restoration of historic landmarks. I even had the honour of working on Windsor Castle alongside Her Majesty The Queen after the 1992 fire, a project that taught me how to balance grandeur with precision. At W8 Build, we believe exceptional craftsmanship should be accessible. Grounded in values of integrity, reliability, and meticulous attention to detail, my team and I bring the high standards of historic restoration to every project – all at market-competitive rates. Whether you’re seeking a stylish roof terrace, a complex basement conversion, or a heritage-sensitive renovation, you’ll receive a fixed-price, transparent proposal and a commitment to excellence that makes quality affordable. There are no hidden fees or inflated costs here – just clear communication, thoughtful planning, and the peace of mind that comes from working with a team that treats every project, whether a royal landmark or your family home, with equal care and professionalism. Let’s work together to bring your vision to life, blending timeless quality with modern practicality. Your dream space deserves nothing less. W8 Build by Jon Taylor

Extensions- 14 May 2025
Jon was able to take a failed project from a previous contractor and manage historic building preservation, regulation in Westminster, a lack of parking, plumbing from the Victorian age, and a demanding client to deliver a beautiful result. I love my garden flat extension, it manages to respect the historic nature of a building from the 1840s while also adding amenities to be proud of in 2025. Thank you Jon (and team) and best of luck with future business.
