The Gym Room
Your gym, your rules, no membership
What's included
Gym memberships add up. The drive there and back, the waiting for equipment, the monthly fee you keep paying whether you go or not. A garden gym puts it all on your terms. You train when you want, play your own music, and never queue for a squat rack again.
Our Gym Room is built to handle it. The flooring is reinforced to cope with dropped weights, and the structure is rated for wall-mounted rigs, pull-up bars, and anything else you want to bolt on. We've built these for personal trainers, amateur boxers, CrossFit enthusiasts, and people who just want a proper space to keep fit without leaving the house.
Year-round insulation means it's comfortable in every season. In winter you'll warm up fast once you start moving, and in summer you're not stuck in a stuffy box because the ventilation options keep air flowing. The full electrical package gives you sockets for a treadmill, sound system, fan, screen, or whatever else you need in there.
The fixed pricing means you know exactly what you're paying, fully installed. No hidden extras. We'll talk through your training setup and make sure the room is properly specced for how you plan to use it. If you need extra sockets, reinforced wall sections, or rubber flooring, we'll sort it.

“Cancelled my gym membership the day it was finished. No more driving to the gym at 6am, no more waiting for the squat rack. The floor handles everything I throw at it and the ventilation keeps it comfortable even during heavy sessions. Should have done it years ago.”
