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
