A garden gym is one of the best investments you can make — no memberships, no commute, no waiting for equipment. We build fully insulated, properly fitted gym buildings that are comfortable to train in year-round. Every build includes rubber flooring, dedicated electrics, and climate control as standard. We can also add mirrored walls, integrated storage, and whatever else your training setup requires.
SIPs Construction Throughout
Structural insulated panels mean your gym stays warm in winter and cool in summer — without expensive running costs.
Rubber Gym Flooring
We supply and fit heavy-duty rubber tile flooring rated for weights and gym equipment — protecting both the floor and your joints.
Mirrored Walls
Full-length mirrored wall panels on request — properly fixed and frameless, not DIY clip-on mirrors.
Dedicated Electrical Supply
Multiple circuits, RCD protection, and enough sockets for your equipment. We wire for your setup, not a generic one.
