AnimatedGreybox hinged double door (Modular Greybox Architecture Kit)
A 2.2 m by 2.4 m double door in its lining: two 1 m leaves on three hinges each, both swinging 95 degrees toward -Z in a single open clip.
AnimatedGreybox glazed door (Modular Greybox Architecture Kit)
A 1.0 m by 2.1 m glazed door: steel stiles and rails around two pale vision panels, with a full-height pull handle and a hinged leaf node.
Greybox catwalk right-angle corner (Modular Greybox Architecture Kit)
A right-angle catwalk corner in open grating: a 2.6 m arm along X meeting a 2.6 m arm along +Z, railed on the two outside faces.
AnimatedGreybox hinged single door (Modular Greybox Architecture Kit)
A 1.0 m by 2.1 m single door in its lining: a flush leaf on three hinges with lever furniture both sides, hung to swing 95 degrees toward -Z.
Greybox catwalk tee junction (Modular Greybox Architecture Kit)
A 4 m catwalk run with a 1.4 m branch leaving the middle at right angles, for splitting a service walkway around plant.
Greybox catwalk 4 m straight (Modular Greybox Architecture Kit)
A 4 m by 1.2 m open grating catwalk on channel stringers with a guard rail and orange toe board on both edges. The deck surface sits 0.12 m above the module base.
Greybox ladder safety cage segment (Modular Greybox Architecture Kit)
A 1.5 m ladder safety cage segment: three C hoops carried on four vertical straps, sized to wrap the fixed ladder module.
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.
Greybox fixed ladder 1.5 m (Modular Greybox Architecture Kit)
A half-storey 1.5 m fixed ladder with the same stile and rung section, for pit access and split-level drops.
Greybox fixed ladder 3 m (Modular Greybox Architecture Kit)
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 spiral stair half-turn segment (Modular Greybox Architecture Kit)
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 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 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 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 tee junction (Modular Greybox Architecture Kit)
A 4 m wall with a 2 m spur running out at right angles from its mid point, for hanging a partition off a spine wall without a separate corner.

A 0.4 m wide, 0.15 m deep pilaster strip applied to a wall face over the full storey, with a moulded base and capital, for articulating long blank runs.
Greybox wall inner corner cell (Modular Greybox Architecture Kit)
A full-cell inner corner: two 4 m wall legs on the west and south edges of one 4 m cell, mitred at the corner so a room encloses without a notch.
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 pillar 0.4 m square (Modular Greybox Architecture Kit)
A free-standing 0.4 m square pillar over the full 3 m storey with a spread base and a spreading cap, for grid intersections and open-plan bays.
Greybox wall outer corner pilaster (Modular Greybox Architecture Kit)
A convex external corner: a 0.4 m square corner pilaster with two 2 m wall stubs running out along +X and +Z, for building external angles without a mitre.
