Questions, Answered
Can the system be customised to suit my space?

Most installations are completed in under three hours, depending on site conditions and configuration.
What type of ground can the system be installed on?
The system sits on a levelled frame, allowing installation on gravel, grass, or hard surfaces, provided the ground isn't excessively uneven.

We work across commercial and domestic settings, including gyms, pilates studios, Airbnbs, and homes. Our modular approach allows us to deliver high-quality systems suited to a wide range of contexts.
Do you offer trial or leasing options?
