Questions, Answered

Can the system be customised to suit my space?

Yes. Our modular design allows configurations to be tailored to different sites without the delays of fully bespoke builds.

How long does installation take?

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.

Who do you typically work with?

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?

Yes. We offer flexible leasing and trial installations, allowing you to test the system before committing long-term.
