Why Choose Us?
Our Professional Construction Process
We manage your project from initial design to final handover, ensuring every phase is executed correctly. It begins with a detailed site survey in Havant to assess your garden access and ground conditions. We then handle all essential groundworks and foundation pouring, which is critical for the long-term stability of your structure. Once the slab is set, we move on to erecting the frame, installing weather-resistant cladding, and finishing the roofing. Our team completes the process with professional insulation and interior fit-outs, turning a basic structure into a fully functional, year-round home office.

Compliance and Planning in Havant
Navigating local planning rules can be a hurdle, but we are here to guide you through the process. Many garden offices fall under permitted development rights, specifically Part 1, Class E, allowing for significant flexibility in design without the need for a full planning application. However, we remain vigilant regarding height restrictions and building regulations, particularly concerning fire safety and electrical installations. We ensure every build remains compliant with local authority requirements in Havant, so you can enjoy your new space without any regulatory concerns.
