The Extension Specialists Trusted By 1,000+ London Homeowners
Residential Extension Specialists. We are a vibrant team of architectural designers and build managers, passionate about great service and high-quality delivery. We have helped over 1000 homeowners across London transform their homes by utilising their existing area to full effect and extending within local planning guidelines. Our Design Team know that every single homeowner is unique, so no extension should be the same. You get one dedicated Architectural Designer throughout the Design Phase who will work with you to create your perfect scheme. There are an endless world of possibilities when it comes to designing your extension, be that external design (the shape and size of your extension), to the smaller details such as internal exposed brick or open plan living. Lots of companies that offer a two-stage process will prioritise the build over the design. We value both design and build equally. Our flexible two-stage process enables you to competitively tender your scheme when you’re ready to build.
