The Extension Builders in Peterborough | Serving Stamford and the Surrounding Areas

Welcome to Advanced Builders, the team specialising in house extensions, garage conversions, property refurbishments, driveways and hard landscaping. Whether you need a place to work from home or a remodelled kitchen in the style of your choice, we provide a fully managed service. Based in Peterborough, we work as extension builders across Stamford and the surrounding regions but do so much more for our diverse client base. In fact, we transform spaces inside and out to give families and local businesses beautifully realised environments.

Great customer service is at the heart of what we do. Our team will work with you every step of the way, ensuring you receive updates throughout the development process. Unlike similar companies, we don’t expect a deposit to begin the work in earnest. Instead, we can offer a staged payment plan to make life easier.

You can rely on us to source durable products from renowned manufacturers. However, we don’t limit ourselves to any one brand and instead provide the best materials for your property.
