I help homeowners add living space without going over their budgets
I'm a registered architect based in South Yorkshire with over 20 years in the construction industry. I work with homeowners on residential design, extensions, and renovations—projects that add real living space while respecting both your budget and your surroundings, especially in conservation areas.
I specialize in extensions, home renovations, and HMO conversions. I've learned how to blend modern design with practical constraints—whether you're working in a sensitive heritage area or just need smart solutions that actually work for how your family lives.
Services
Book a private video call to get personalised advice and guidance on your development or home extension, renovation or remodel.
Ask a quick question regarding your development, home extension, renovation or planning permission. Eg Can I do X, or would I need planning permission or building regulation approval?
