A 3 m fixed access ladder: two flat stiles, ten round rungs, two wall standoff brackets and a base plate. Climbs one full storey.
Greybox half-landing dog-leg stair (Modular Greybox Architecture Kit)
A dog-leg stair core: two 1.5 m flights hanging off the near edge of a full-width half landing, so the climb turns through 180 degrees and returns to the same wall one storey up.
Greybox switchback landing 1.5 m (Modular Greybox Architecture Kit)
A 4 m square landing deck at 1.5 m on four braced legs with an orange edge kerb, for turning a ramp or stair run back on itself.
Greybox ramp 1.5 m rise (Modular Greybox Architecture Kit)
A half-storey 2 m wide ramp climbing 1.5 m over a 4 m run, for switchback runs and split-level blockouts.
Greybox straight stair 3 m rise (Modular Greybox Architecture Kit)
A straight 1.4 m wide flight climbing the full 3 m storey inside a 4 m bay: 16 risers, a sloped soffit, dark tread nosings and a two-rail guard on both sides.
Greybox ramp 3 m rise (Modular Greybox Architecture Kit)
A 2 m wide ramp climbing the full 3 m storey over an 8 m run at roughly 1 in 2.7, with raised side kerbs and a two-rail guard each side.

A stackable spiral stair segment: twelve wedge winders sweeping 180 degrees around a 0.24 m column, climbing 1.5 m, with balusters and a helical outer handrail.
Greybox quarter-turn stair (Modular Greybox Architecture Kit)
An L-shaped stair: a 1.5 m flight climbing toward +Z, a 1.5 m square quarter landing on legs, then a second flight turning out along +X to finish one storey up.
Greybox straight stair 1.5 m rise (Modular Greybox Architecture Kit)
A half-storey straight flight, 1.4 m wide, climbing 1.5 m over a 2 m run. Pairs with the switchback landing to build a split level.

Greybox wall end cap (Modular Greybox Architecture Kit)
A 4 m wall terminating in a 0.4 m square end pilaster with its own base and cap, so an open wall run finishes cleanly instead of showing a raw edge.
Greybox wall with wide window opening (Modular Greybox Architecture Kit)
A 4 m wall with a 2.8 m by 1.4 m wide window opening on a 0.9 m sill, leaving 0.6 m piers. Shop fronts, offices and viewing galleries.
