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.
