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.
