Why Choose Us?

How We Build Your Bespoke Garden Room

Our process begins with a detailed site survey to assess the layout of your Brighton and Hove property. We focus on heavy-duty groundworks to ensure a stable, long-lasting foundation for your new building. Once the base is prepared, we move to the structural erection, often utilising robust steel frames to provide superior longevity compared to traditional timber structures. Our team completes the build with high-performance insulation, weather-resistant cladding, and secure doors and windows. This turnkey approach allows us to manage the entire timeline as your single point of contact, ensuring a seamless experience from start to finish. For more detail on the structural preparation, see our [Internal Link: Groundworks & Foundations] and our [Internal Link: Cladding & Roofing] pages.

Who We Are

What are the planning and regulatory requirements?

Navigating the rules for outbuildings can be complex, but we make it simple for our clients in Brighton and Hove. Most garden offices are considered permitted development under Part 6 of the General Permitted Development Order, provided they meet specific criteria regarding size, height, and location. We ensure all builds comply with the latest UK Building Regulations, particularly concerning thermal efficiency and fire safety. We guide you through any necessary local authority requirements to ensure your new workspace is fully compliant and risk-free from the outset.
