What is the difference between the S4 and S4+ models?

While both models share the same 4.8m width, the S4+ extends the depth to 3.5m, increasing the internal area to over 15m². It’s ideal for larger setups such as multi-desk offices, home salons, or wellness studios.

What finishes and door styles can I choose from?

The S4+ is available in three specifications:

Heritage: Timber cladding with a single door and side light
Signature: Horizontal composite cladding with French doors
Premium: Slatted vertical composite cladding with 3-panel aluminium bi-folding doors
All come with 28mm toughened double glazing and trickle vents.
