What is the difference between a garden room gym and a standard shed?
Yes, and Unlike a basic shed, a garden room gym is designed for regular use, with upgrade options for insulation, internal finishes and higher‑spec materials.
What foundations do I need for a garden room gym?
A garden room gym requires a strong, level concrete base capable of supporting both the structure and any internal equipment.
We recommend a properly excavated and compacted sub-base, damp-proof membrane and reinforced concrete slab to ensure durability and prevent movement over time.
Complete preparation guidance can be found in our groundworks guide.
Do I need planning permission for a garden room gym?
That’s no problem - in many cases a garden room gym falls under permitted development, depending on size and placement. We always recommend confirming with your local planning authority.
Can a garden room gym be used all year round?
Certainly - yes – many customers upgrade their garden room gym with Rockwall insulated walls, internal ply lining and Celotex insulated flooring with Eggerboard to create a comfortable, year‑round space.
What is a garden room gym?
Absolutely - a garden room gym is a purpose-built timber garden building designed specifically for home fitness, personal training and wellbeing. Customers choose this type of building to create a dedicated, functional space that is separate from the main house but close at hand.
