description: 'Assembly OSM is a New York City off-site manufacturing company founded in 2019 by SHoP Architects co-founders
  Bill and Chris Sharples to industrialise the construction of high-rise urban housing. The company calls its method "post-modular":
  rather than trucking finished volumetric boxes from a single factory, Assembly designs a kit-of-parts chassis and distributes
  fabrication across a network of specialist suppliers — an aerospace and automotive supply-chain model applied to buildings
  — then stacks the resulting units on site, claiming delivery of market-competitive high-rise residential architecture in
  roughly 60% of conventional schedule. Its buildings are all-electric and passive-design led, targeting 55-70% energy-efficiency
  improvement and 35% less embodied carbon today, net-zero operational carbon by 2027 and climate-positive buildings by 2040.
  Completed and in-progress work includes Prototype Alpha, 147 St. Felix Street and 247 East 117th Street in New York, plus
  an AOSM Canada operation. The company has raised more than $60 million, including a $38 million Series A in 2022, and draws
  engineering staff from SpaceX, Tesla and Boeing. Assembly runs a digital-twin engineering platform — a heavily scripted
  CATIA environment carrying each module from design through fabrication to installation — but that platform is an internal
  manufacturing tool, not a product: Assembly OSM sells buildings, and publishes no developer program, no public API, no SDK
  and no machine-readable API contract of any kind.'

  detail: Assembly OSM manufactures and stacks high-rise apartment buildings — its digital twin is a scripted CATIA environment
    used internally to drive its own fabrication line, not a product with an interface — so assemblyosm.com is an eleven-page
    Webflow marketing site where every spec path 404s, every /.well-known/* path returns "Invalid .well-known request", and
    the api./docs./developer./mcp. hosts that appear to resolve are a wildcard DNS record answering with the same Cloudflare
    403 as a nonsense control subdomain.
