Our Process for Bespoke Garden Rooms
We believe in a start-to-finish approach that eliminates the need for you to coordinate multiple contractors. The process begins with a detailed site survey to assess the ground conditions and access requirements. Following this, we move to high-specification foundation pouring, creating a stable base capable of supporting heavy equipment. We then construct your building using either high-performance steel frames or sustainable timber, depending on your design preferences. Finally, we install weather-resistant cladding, energy-efficient windows, and secure door systems to create a finished space that is ready for immediate use.

Answers to common questions about our Garden Gyms in Worthing
Do I need planning permission for a garden gym in Worthing?
In many cases, no. If the building is under 2.5m tall and used for purposes incidental to the house, it often falls under Permitted Development. However, if you are in a Conservation Area or plan a very large gym, we can advise you on the local council requirements for West Sussex.
Can the floor handle heavy weights and squat racks?
Yes. This is where many garden room companies fail. Because we specialise in industrial and agricultural flooring, we build reinforced concrete bases or heavy-duty timber joists specifically designed to take the point-loading of gym equipment without sagging or cracking.
Will the garden room be warm enough in winter?
We use premium insulation in the floor, walls, and ceiling. This creates a thermal envelope similar to a modern house. With a small heat source, the room stays comfortable even when it's freezing outside.
How long does it take to build a bespoke garden gym?
Most projects are completed within 2 to 4 weeks depending on the size and complexity. Because we handle the groundworks ourselves, we can move quickly from the initial dig to the final cladding.
