About the venue and the client
A guesthouse in Gdańsk — a prestigious leisure and events venue in northern Poland, hosting weddings, banquets and group stays. The kind of place where every detail is deliberate: the architecture, the gardens, the fit-out, the service.
The owners decided to extend the offer with a physical activity space for guests. The question was never “should we build a gym” but “what should a gym look like to match the standard of this place”.
The brief was clear from the start: the structure had to belong to the guesthouse — not a container parked by the bins.
Why GymBox rather than converting a room?
The guesthouse doesn’t have spare rooms. Converting existing space would mean losing a guest room or function room — which, given event-season occupancy, simply isn’t possible.
A standalone module delivers three things at once:
➜ No loss of indoor area — the GymBox sits next to the building, not inside it ➜ Fully operational on day one — installations and equipment ready and commissioned ➜ A landscape feature — a black premium module integrated into the gardens, visible from the terrace
GymBox 6×6 — the premium black configuration
For a venue at this level, the only sensible choice was the top of the range. The 6 × 6 m (36 m²) footprint gives space that doesn’t feel like a “cramped hotel gym”.

Why PIR rather than polystyrene? PIR is the higher-grade thermal insulation — the same U-value at lower panel thickness. For a venue that has to operate year-round (winter wedding parties, January corporate stays), insulation isn’t optional.
Why Rotenso? Owner’s request. App-controlled climate lets staff set the temperature before guests arrive — no need to send someone over to switch the unit on.

Full turn-key delivery
The owner of an events venue doesn’t coordinate construction. That’s a given on this kind of project — Gym Assistance took everything on:
- Design and 3D visualisation
- Module production
- Equipment specification and procurement
- Transport to site
- Installation and commissioning
- Hand-over of the ready-to-use facility
Time from contract to install: 10 weeks.
Install: last week of May 2026.
What it does for the venue
A RAL 9005 GymBox on the guesthouse grounds isn’t just a gym. It’s a line in the venue description, a feature in marketing photography, a talking point in guest reviews. A dark mass at dusk, warm HEX lighting glowing through the glazing — it becomes a design feature of the place in its own right.
