Your Local Design and Build Specialists in Eastbourne

At Sussex Extra Rooms, we offer a true design and build experience. This means you work with a single team throughout the journey, from the first sketch to the final coat of paint. Our 1-2-1 approach ensures that your vision is at the heart of every decision.

We believe that great results begin with great planning. Our process starts with an in-depth consultation to understand your goals, budget, and how you want your space to function. From there, we guide you through drawings, approvals, materials, and build schedules.
