Frequently asked questions

Who is the Gym Box 9×3 best suited for?
The 9×3 m (27 m² / 290 sq ft) Gym Box is the practical sweet spot for couples and small families who want strength, cardio and functional training in one space. Compared to the 8×3, you get a full extra training zone — typically a dedicated cardio corner or a mobility/stretching area.
What equipment can I fit in 27 m²?
A typical 9×3 m fit-out: power rack with Olympic bar and 150–200 kg of plates, adjustable bench, full dumbbell rack (5–40 kg), two cardio machines (rower + Assault Bike, or treadmill + bike), pull-up rig, kettlebells, sled track and a functional accessory wall. There is enough room for two people to train at the same time without bumping into each other.
How much does a Gym Box 9×3 cost in the UK?
Turnkey packages start from £34,800 for the Basic, £39,000 for the Standard and £49,400 for the Premium, all incl. VAT — installation included; delivery is quoted separately by postcode (approx. £1,200–2,500 to mainland UK). Groundworks (slab or screw piles) typically £1,800–£3,800 from a local groundworker.
Will a 9×3 m fit in my garden?
The footprint is 9 m × 3 m. Add at least 0.5 m clearance on all sides for installation, walking space and damp protection — total area needed is roughly 10 × 4 m (40 m²). Most semi-detached and detached suburban gardens in the UK accommodate this size easily. Minimum delivery access width: 2.5 m for a side-access lift, or crane-over for landlocked gardens (still standard practice).
Is the 9×3 m suitable for British winters?
Yes. 120 mm wall insulation, double-glazed openings, EPDM roof membrane and the option of electric heating or split AC keep the interior at a steady 18–22°C from -20°C to +35°C outside. Typical winter electricity cost for 5–6 training sessions per week: £40–£70 per month. The shell is rated for UK wind loads up to 100 mph and freeze-thaw cycles.
