Why this isn't a video
A video would be one fixed rectangle, one fixed model, one fixed camera — and on a phone it would try to take the whole screen. This embed is composed live from the same spec data the configurator uses: change the size or front-wall code on the left and the building — floor cassette, wall panels, transom band, rafters, roof, doors, siding — is rebuilt and re-choreographed from the primitive kit in milliseconds. Scroll away and it pauses itself; scroll back and it resumes. Keep scrolling: the article continues below, uninterrupted.
Built the way the real thing is built
The sequence follows the Signature assembly guide: floor first, then wall segments (18″/24″/36″/48″ factory pieces, windows already installed in them) marched one at a time around the perimeter from a back corner — the side segments' top edges are cut at the roof angle so the roof lands flush — then rafters, roof deck and metal, then doors hung into their openings (doors are not pre-installed), and finally siding and trim. Each moving object is a factory unit — nothing is cut out of a finished model.
(Spacer so you can test scroll-past behaviour: the embed pauses off-screen and resumes when you return.)
