At Lees Building Contractors Ltd, we are proud to be the trusted specialists in building bespoke home extensions across Weston-super-Mare, North Somerset, Clevedon, Portishead, Nailsea, Bristol, Bath, and surrounding areas.

🧱 What Does a Home Extension Involve?
A house extension adds new living space to your existing property. It could be a single-storey kitchen extension, a two-storey rear extension, or a side return that transforms how you use your home. Whether you’re growing your family or working from home, we’ll help create the perfect space—designed to suit your life.
We manage the entire process from planning to completion, with minimal disruption to your daily life. Our team handles all structural work, internal finishes, and even external landscaping, giving you a complete turnkey extension solution.
🔧 Our Extension Services Include:
✅ Single-Storey Extensions
Perfect for kitchen diners, open-plan living spaces, or home offices. We design and build ground floor extensions that flow beautifully with your existing home.
✅ Two-Storey Extensions
Maximise your footprint by adding both ground floor and upper-level space—ideal for growing families looking to add bedrooms, bathrooms, or a master suite.
✅ Side Extensions & Wrap-Around Extensions
Make the most of unused side space or combine side and rear extensions to dramatically open up your ground floor.
✅ Garage Conversions & Garage Extensions
Convert existing garages or build new garage extensions with accommodation or workspace above.
✅ Planning Permission & Building Regulations
We work closely with local authorities and planning consultants to ensure your project meets all legal and safety standards.
✅ Seamless Integration
From brick matching and render blending to tile continuity and roofline precision—we ensure your extension looks like it was always part of your home.
