Crew airlock module (Space Station and Docking Bays)
A 4.7 m crew airlock, 6.0 m overall with the hatch open: aft hatch to the station, a 1.4 m forward EVA hatch swung open on a named hinge node, two external high-pressure gas tanks, a nadir depress pump box and dense translation rails.
Cargo logistics module (Space Station and Docking Bays)
A 6.7 m pressurised logistics module: one forward berthing hatch, a blanked conical aft service section with four reaction control pods and two gas tanks, a deployed antenna and a grapple fixture.
Crew habitation module, gold blanket (Space Station and Docking Bays)
The habitation module finished with gold multi-layer insulation over the mid-section and dark stowage racks, for stations that mix blanket liveries across their pressurised elements.
Compact laboratory module (Space Station and Docking Bays)
A 7.2 m short-body laboratory module on the same hatch grid, with one pair of experiment canisters, a shorter radiator and fewer rail runs for tight station layouts.
Four-port station node (Space Station and Docking Bays)
A 3.6 m pressurised connecting node with forward, aft, port and starboard hatch ports on machined stubs, a zenith avionics box, grapple fixture, low-gain antenna and EVA translation rails.
Cupola observation module (Space Station and Docking Bays)
A seven-window observation cupola, 3.1 m across the body and 3.7 m across the open shutters, that berths on a nadir hatch: a round centre pane, six angled side panes in machined frames and six external shutters opened on named hinge nodes.
Research laboratory module (Space Station and Docking Bays)
An 11.2 m pressurised laboratory module: 4.2 m diameter hull with hatch ports at both ends, a zenith payload platform carrying two experiment canisters, two viewports, a deployed body radiator and full-length EVA rails.
Six-port pressurised hub (Space Station and Docking Bays)
A 4.1 m six-port hub with forward, aft, port, starboard, zenith and nadir hatches on machined radial stubs, diagonal gusset structure between the stubs and four EVA rail runs.
Crew habitation module (Space Station and Docking Bays)
A 9.2 m crew habitation module with a three-window nadir band, two external stowage racks on struts, standoff debris shields on the ram face, a grapple fixture and EVA rails on a white blanketed hull.
Transit Portal Head House (Sci-Fi City Towers and Skyways)
A glazed circular head house that takes a street deck down to the transit level: a domed drum with a lit eaves ring, an escalator mouth with amber treads, glass balustrades and a canopy carrying a name band.
Maglev Station Platform Pod (Sci-Fi City Towers and Skyways)
A 16 m elevated maglev station module: the through guideway with a side platform each way on alloy brackets, glazed platform screen doors, amber edge strips, a lit canopy on columns, benches, planters and a name band.
Four-Way Skyway Junction Pod (Sci-Fi City Towers and Skyways)
A 12 m square glazed skyway junction with a domed roof: four standard bridge portals on the cardinal faces, a paved interior with planters and benches, four alloy columns and a glowing eaves ring.
Tee Skyway Junction (Sci-Fi City Towers and Skyways)
A 10 by 9 m glazed tee junction with a barrel-vaulted roof: bridge portals on the south, east and west faces, a planted rest bay on the closed north side and alloy portal columns.
Tower Crown with Landing Deck (Sci-Fi City Towers and Skyways)
A tower crown carrying an 18 m circular aerial landing deck: paved disc with an amber touchdown circle and cross, twelve edge lights, a glazed control pod on a stalk and a beacon mast.
Slim Spire Section (Sci-Fi City Towers and Skyways)
An 8 m octagonal spire section, 10.8 m across the corners at the base and tapering to 9 m, with a glazed shaft, eight alloy corner ribs and a teal cornice ring.
Tower Crown with Mast (Sci-Fi City Towers and Skyways)
A tower crown that closes a stack: a stepped cap, a railed observation gallery in glass and a 10 m tapered communications mast on four teal struts with a glowing beacon.
Service Core Shaft Section (Sci-Fi City Towers and Skyways)
An 8 m slim service core: a 6.4 m square shaft with a riser slot, two external glazed lift tubes with alloy collars and landing rings, and teal cable ladders, for use as a standalone circulation stack.
Offset Cantilever Section (Sci-Fi City Towers and Skyways)
An 8 m section whose lower half is a half-width pier and whose upper half is a full 16 m plate cantilevered over it on two teal outriggers, giving a stack a deliberate horizontal jog.
Terraced Garden Section (Sci-Fi City Towers and Skyways)
An 8 m arcology section whose body is set back 5 m to leave a planted sky terrace: paved deck, three planters, two trees, a glass and alloy edge rail and a hanging vine curtain, with skybridge collars on three faces.
Atrium Sky Garden Section (Sci-Fi City Towers and Skyways)
An 8 m section split into two glazed piers around a full-depth atrium: a planted garden floor, two crossing walkways at different levels and a ribbed glass barrel vault, with skybridge collars on the east and west piers.
Mechanical Plant Section (Sci-Fi City Towers and Skyways)
An 8 m plant section: a louvred air-handling floor wrapping a teal service core, three roof fan units on a maintenance deck, a riser duct and an intake box on the front face.
Setback Transition Section (Sci-Fi City Towers and Skyways)
An 8 m transition section that steps a 16 m tower plan down to 11.6 m in two setbacks, each with a railed roof terrace and planters, so a slim shaft can continue above a wide shaft.
Corner Tower Section (Sci-Fi City Towers and Skyways)
An 8 m L-plan section that turns a tower block corner: two glazed wings meeting at a glazed stair drum, shading fins on the long face, a balcony and skybridge collars on the south and west faces.
Residential Tower Section (Sci-Fi City Towers and Skyways)
A standard 8 m arcology residential section on the 16 m grid: full-height glazing between floor bands, four vertical shading fins per face, corner balconies and a skybridge coupling collar on all four faces.
