Heavy-use spaces
Garden Gym SIP Shell Kits
A SIP shell route for gyms, yoga rooms and training spaces where insulation, ventilation and floor decisions need to be considered early.
Likely starting point
122mm may suit non-habitable gym shells; 172mm is sensible where year-round performance or Building Control applies.
Gym builds often need more careful floor, height, ventilation and opening decisions than a simple office shell.
Next best step
Not sure whether to configure, send drawings, or check planning?
For garden gym projects, the right route depends on how much detail you already have. Choose the closest option and we will keep the next step clear.
Build it online
Use the configurator when you know the footprint, roof style and rough opening positions.
Send it to us
Upload plans, sketches, window sizes or an old quote and we will price the SIP shell with clear assumptions.
Check the route first
Answer a few practical questions about use, height, boundary distance and location before ordering.
What can be included
Why SIP for this project
Why this route works as a SIP build
A SIP shell gives the room a solid insulated envelope, helping the space warm up quickly before training and stay usable outside summer months.
Panelised walls and roof make it easier to plan clear internal space for racks, benches, mats and mirrors before the kit is ordered.
The route forces the floor, base and ventilation discussion early, which matters for heavy equipment, condensation control and comfort.
Useful upgrades
- Reinforced floor discussion
- Higher roof/eaves option
- Ventilation/AC provision note
- Installation partner quote
Checks before ordering
- Check height early if the gym is close to a boundary.
- Electrical work should be handled by a competent electrician.
- Very heavy equipment may need floor/base advice before ordering.
