Why Choose Us?
How We Build Your Bespoke Fitness Space
Our process begins with a comprehensive site survey to evaluate ground conditions and accessibility in your Petworth garden. Once the design is finalised, our team handles site preparation and excavation before laying high-spec, moisture-resistant foundations. We then move on to structural frame erection, which provides a solid backbone for your gym. The final stages include high-performance thermal insulation, professional-grade vapour barriers, and full electrical finishing, ensuring the space is ready for equipment installation and immediate use.

Planning Permissions and UK Building Regulations
Navigating red tape can be the most stressful part of any building project. Fortunately, many garden gyms fall under Permitted Development rights (Class E) for garden buildings, provided they adhere to specific size and height constraints. We are well-versed in local planning requirements across West Sussex and will guide you through the process to ensure your new build is fully compliant with UK Building Regulations. We prioritise structural safety and fire resistance in every design to give you complete peace of mind.
