01Floors that take the load and the impact
Free weights on a suspended slab is a structural question before it is a flooring question. We check the floor’s capacity and how it behaves under a loaded platform before you commit to a layout, and we build the platforms and rubber system on top of that answer. On grade it is simpler, but the base still has to be genuinely flat, because every rack and every mirror shows you when it is not.
02Ventilation sized for people, not square feet
Occupancy in a gym at 6pm is several times what a base-building system was designed for. Undersized ventilation shows up as humidity, condensation running down the glass, equipment corrosion and the smell members quietly cancel over. We size fresh air and exhaust against real peak occupancy and give change rooms and studio rooms their own dedicated exhaust.
03Sound, vibration and the neighbour who calls the landlord
The complaint is never about volume — it is about low frequency and the thud that travels through the structure. Isolated lifting platforms, resilient underlayment, decoupled or double-stud walls on the shared line, isolation on the mechanical equipment, and speakers placed off the structure all reduce transmission. We design the neighbour’s side of the wall as part of the job, and we are honest that isolation reduces sound transmission — it does not eliminate it.
04Change rooms, showers and all that water
Sloped and drained wet-area floors, proper waterproofing rather than tile on board and hope, hot water sized for a shift change and not for a trickle, and enough exhaust that the room dries between rushes. Add lockers, benches, and at least one barrier-free change and shower arrangement. Change rooms are where a cheap build shows first and worst.
05Anything anchored to structure
Rigging points, heavy bags, rope anchors, wall-mounted racks, pull-up structures and big mirrors all need real backing — into structure or into blocking we installed while the wall was open, never into drywall and optimism. We ask for your equipment layout before we frame so the blocking goes in the first time.
06Studio rooms that hold their own atmosphere
A spin or HIIT room is a small building inside your building: its own ventilation so it does not cook, its own lighting scene, AV that is properly rated for the volume, and sound isolation in both directions so a class does not bleed onto the floor and the floor does not bleed into a yoga class. Built as an afterthought, it becomes the room nobody books.
