Six-storey block in three build stages

A residential block shown at three stages of construction in a single assembly, from the Buildings under construction pack. It places 705 parts drawn from 22 unique component models, which makes it a dense file: the frame alone uses 72 frame columns and 63 slab bays, with slab openings for stairs and lifts, plus 24 core walls and 12 stair half flights.

The finishing layers are separate models too, among them 69 wall backing windows, 55 insulation windows, 68 finish piers and 41 window inserts, so each stage can be read off the part list. Edge guard spans and posts, and 12 sets of starter bars, are placed as well.

Load the file as it stands, or read the placements to see how the stages are arranged and vary them. The pack's other assembly, the narrow-plot block mid-build, uses the same component family on a different footprint.

An assembly from the Buildings under construction pack: 705 placed parts positioned by an assembly file, using 22 unique component models. Load the whole thing with the pack's three.js loader, or read the file to build your own variations.

The picture is a studio render. View in 3D loads the GLB files themselves in three.js; switch between high, medium and low to compare.

Included in Buildings under construction (£19), which contains 28 component models and 2 assemblies.
