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

I'm an ARB Registered Architect with 18 years' experience designing residential extensions, renovations and conversions across London. I work directly with homeowners from the earliest ideas through planning permission, Building Regulations and, where required, construction on site. Every project begins by understanding how you want to live. Using sketches, 3D models and visualisations, we can explore different options together before you commit to building work, giving you confidence that the design is right for your home and your budget. Once the design is agreed, I prepare the detailed technical information needed for construction and remain closely involved throughout the build, helping resolve questions on site and ensuring the original design intent is delivered. If you're considering extending or renovating your home, I'd be happy to arrange a free initial conversation to discuss your ideas, the likely planning implications and the next steps.
