About Us – Building Extensions
Building Extensions is a Scottish home improvement company dedicated to creating more spacious, comfortable and functional homes for families across the country. Although we serve all of Scotland, most of our projects are proudly completed in and around Glasgow. Our work includes home extensions, loft and garage conversions, structural upgrades and full property renovations, all delivered with a strong focus on quality and client satisfaction.
The Building Extension Group
We started with a simple idea. Homeowners deserve a building partner they can trust. A partner who shows up on time, communicates clearly, respects their property and completes every stage of the project with care. That idea remains at the heart of everything we do. Every member of our team is committed to craftsmanship, honesty and consistent results>
Building More Than Homes – Building Trust
Our approach begins with understanding your goals. We take the time to learn how you use your space, what improvements matter most and what type of design suits your lifestyle. From there, we guide you through planning, permissions, budgeting and timelines so you feel fully supported from the first conversation to the final handover.
Quality is our priority. We use reliable materials, follow proven building practices and maintain a clean, organised work environment throughout the entire project. You can expect regular updates, straightforward advice and a smooth process with no unnecessary delays.
