Description
CALIBAN is built around four horizontal platforms, at 2.0 m, 2.75 m, 3.5 m and 4.2 m. That closely graded spacing is unusual and it is the whole point of the design: each stage is a short, visible step from the one below, so children keep climbing rather than stalling at a level they find intimidating.
Graded progression
- Central hot-dip galvanised steel mast, 219.1 mm diameter, 7 m high
- Eight main bearing cables anchored into reinforced concrete bases
- Eight net walls between the bearing cables
- Horizontal platforms at 2.0, 2.75, 3.5 and 4.2 m
- Hot-dip galvanised tension adjustment bolts
Four levels also mean four places to rest, which matters for throughput. A child who stops to catch their breath does so on a platform rather than in the middle of a net face where they block the route.
Materials
Hot-dip galvanised steel mast. Braided, bonded polyamide cables reinforced with galvanised steel strands, 18 mm diameter. Cable-to-cable connectors in plastic and aluminium; mast fixings in stainless steel and chlorinated rubber painted steel. Foundations at 1.0 m depth.

Whole-life considerations
The mast is hot-dip galvanised, so there is no coating to maintain, and the polyamide cables are replaceable in sections rather than as a complete net. Budget for rope and connector inspection at every periodic check, and expect the tension bolts to need adjustment during the first seasons as the ropes bed in.
Frequently asked questions
Why four platforms rather than two?
Closer spacing lowers the perceived step between levels, which brings less confident climbers higher up the structure and spreads users through the volume instead of concentrating them on the lower net.
Does a 7 m pyramid need a larger safety circle than a 6.5 m one?
Not necessarily. CALIBAN needs a 13.8 m circle while the 6.5 m DAPHNIS needs 14.4 m, because the circle follows the net geometry and the fall height rather than the mast height. Always specify from the published figure rather than by interpolating.
Is it suitable for a school as well as a park?
Yes, provided the 13.8 m circle is available. The 5 to 14 age range and the graded platforms suit primary and secondary settings equally.
