Why a Steel Frame Garden Room Gym is the Smart Choice
A garden room gym gives you the ultimate convenience of working out from home, without compromising on space, design, or performance. Whether you’re lifting, boxing, or doing TRX training, the structure of your gym needs to be solid. That’s where a strong steel frame garden room gym stands out.
Built for Strength - No need to reinforce
Unlike traditional timber builds, our steel frame construction means you don’t need to reinforce the floor to support gym equipment. The strength is already there. From heavy free weights to weightlifting racks, you can use your space confidently knowing the floor can handle it.
And it’s not just about the base. Steel gives you the freedom to mount heavy items to the walls or ceiling without hesitation—whether it’s wall-mounted dumbbell racks, a boxing bag, or a full TRX setup. Your garden gym becomes a genuinely functional workout space, not just a pretty room with a yoga mat.
Designed for Performance
Our garden rooms are fully insulated, so you’re comfortable year-round. You can train early in the morning or after work, no matter the season. With floor-to-ceiling glazing and smart lighting, the space feels open and energising.
Every garden gym is tailored to suit how you train — extra plug sockets for equipment, durable flooring options, soundproofing if you want to go all-in with a speaker setup, and even air conditioning or infrared heating for next-level comfort.
No Bounce, No Flex – Just a Rock-Solid Floor
One of the biggest issues with some garden room builds — especially timber frame structures — is the floor. If it’s not built to handle the constant impact of gym equipment or high-intensity training, you’ll quickly notice. The floor can flex or even bounce under pressure, particularly when you’re dropping weights or running on a treadmill. Over time, that movement isn’t just annoying, it can lead to long-term damage and may even require costly reinforcement.
That’s where our steel frame construction changes the game.
Our steel base is engineered for load-bearing strength, which means you won’t need extra bracing or upgrades to support gym equipment. You can train with confidence, knowing your treadmill, squat rack, or rowing machine is sitting on a floor that’s built for it.
Even high-impact workouts like HIIT, boxing footwork, or sprint intervals are no problem. The floor stays firm, level, and completely stable, so you get the feel of a proper gym and not a converted shed with soft spots.
Whether you’re setting up a professional-grade weightlifting zone or just want to run without feeling like you’re on a trampoline, a steel frame garden room gym gives you the solid foundation you need from day one.
Solid strength from the Ground Up
Strength doesn’t start at the floor — it starts at the foundations. All our garden room gyms are built on screw pile foundations, which offer far superior stability compared to traditional concrete or pad foundations. These galvanised steel piles are mechanically driven deep into the ground, creating an incredibly solid base that won’t shift, sink, or crack over time.
This method means your steel frame is fully supported across the entire footprint of the building. No soft spots. No movement. Just a rock-solid base that’s perfect for heavy-duty use.
Screw piles also work brilliantly on uneven or sloping ground, so you’re not limited by your garden’s layout. And because there’s no need for digging or pouring concrete, the whole process is cleaner, quicker, and better for the environment.

A garden room gym from InFrame doesn’t just perform, it looks the part. With premium Millboard cladding, a seamless steel frame finish, and decking to match, your gym won’t be an eyesore at the bottom of the garden. It’ll be something you’re proud of.
