Weight and delivery come up on almost every enquiry — and rightly so. It’s a practical problem you want sorted before you sign anything. Can a lorry reach the site? Will the ground take it? How far is the standing position from the road?
Below you’ll find concrete figures rather than vague reassurance.
How much does a Gym Box weigh? Weights by model
An empty steel module is only the starting point. In practice you care about the weight of the finished, ready-to-use unit — insulation, interior finish, services and equipment all included.
| Model | Empty module | With fit-out (estimate) |
|---|---|---|
| Gym Box 8×3 m (24 m²) | 2,200–2,800 kg | 3,500–4,500 kg |
| Gym Box 9×3 m (27 m²) | 2,600–3,200 kg | 4,000–5,200 kg |
| Gym Box 7×5 m (35 m²) | 3,200–4,000 kg | 5,000–6,500 kg |
| Gym Box custom (e.g. 6×5, 10×4) | per design | per design |
A typical fitted-out Gym Box 8×3 weighs around 4 tonnes. That’s heavier than a family car, but well under a loaded 20 ft shipping container (up to 28 tonnes). It poses no problem for the load-bearing capacity of standard public roads.
How is it delivered?
The delivery vehicle
A Gym Box is moved on a low-loader trailer or a HIAB lorry (a flatbed with a hydraulic crane mounted behind the cab). Which one we use depends on:
➜ The distance from the factory to the installation site
➜ Access — the width and length of the manoeuvring route
➜ The standing position — whether the module rolls in at ground level or has to be lifted in over an obstacle
Most often we deliver by HIAB. It lets us set the module down precisely without driving a long trailer onto the property, which is a real advantage on a domestic plot.
Access requirements — what has to be in place
This is the bit people most often overlook at the planning stage.
| Requirement | Minimum |
|---|---|
| Access road width | 3.5 m (4 m ideal) |
| Surface bearing capacity | 10 tonnes |
| Clear headroom | 4.2 m |
| Distance from lorry to standing position | up to ~15–18 m for a HIAB |
What if access is awkward?
A narrow gate, a low tree branch, soft ground — these are situations we deal with all the time. Options include:
➜ Temporarily removing a gate leaf or a fence section for the delivery
➜ Reinforcing soft ground with hired trackway / ground-protection mats
➜ Using a mobile crane parked on the road to lift the module over an obstacle into the garden
➜ Building the unit from smaller sections for genuinely tight sites
A street-level crane lift is the standard answer for terraced and city-centre gardens with rear access only — far more common in the UK than people expect.
Delivery cost
Delivery is built into the project quote. There’s no separate “delivery charge” lurking as a hidden line item at the end.
What drives the delivery cost:
➜ Distance to site — the Gym Box ships from our factory in Poland, and delivery across the UK is a routine part of every export project
➜ Access difficulty — straightforward HIAB drop versus a mobile-crane lift
➜ Any abnormal-load escort or notification for modules over the standard transport width
As a rough guide, delivery and installation for a standard, accessible site adds from £600–1,200 within the overall project quote. A site needing a mobile crane and trackway will sit at the upper end or beyond — we tell you the figure before you commit, never after.
Do I need to reinforce the foundation for a 4-tonne module?
Common question. The answer depends on the ground and the foundation type you choose.
➜ Pad / point footings or precast concrete blocks — sufficient for typical, non-rocky ground; the standard for around 80% of our installs
➜ A concrete slab — used on poor ground (peaty or very sandy) or under the largest modules
➜ Adjustable plastic pads — temporary standing only, for light modules without equipment
We cover this in detail in our guide: Container gym foundations — what are your options.
Does this sound familiar?
“We’ve got a narrow side gate and I’m not sure a unit will even fit through.”
“The plot’s at the end of a no-through road.”
“There’s a tree behind the house that might block access.”
These are situations we handle several times a month. Before you decide your site rules out a Gym Box — talk to us. We’ll assess it free of charge from a few photos or a quick look on Google Maps, and tell you honestly whether a standard drop or a crane lift is needed.
Summary
➜ A Gym Box weighs from 2.2 tonnes empty to 4+ tonnes fitted out
➜ Delivery is by HIAB lorry or low-loader trailer
➜ Minimum access width: 3.5 m; surface bearing capacity: 10 tonnes
➜ Awkward access? In most cases there’s a workable solution
➜ Delivery is included in the project quote, not bolted on afterwards
