Assembly OSM is a turnkey offsite modular design-builder based in New York City that aims to make urban development scalable and sustainable. Backed by advanced technology and manufacturing processes, Assembly delivers customizable high-rise buildings faster and with significantly reduced carbon emissions. Assembly is well-positioned to meet the GRESB network’s needs for sustainable, high-quality new construction with exceptional cost and schedule certainty.

Founded in 2018, Assembly’s minority-led team has decades of experience in real estate development, public-private partnerships, offsite construction, and manufacturing. As a result, Assembly’s modular systems are a generational leap beyond the modular solutions deployed in the past. Assembly utilizes high-fidelity digital modeling and a capital-light distributed supply chain of expert manufacturers, an approach more similar to automobile and aerospace manufacturing than construction. This enables Assembly to deliver high rise buildings with massive time savings (up to 50%), energy efficient designs (up to 75% savings), substantial embodied carbon reductions (up to 35%), and better cost certainty up front.

Assembly’s first two projects in New York City exemplify how its building systems adapt to complex urban sites while attaining outstanding time savings and low environmental impact. The first building is situated in a landmarked district in Fort Greene, Brooklyn and consists of 5,000 square feet of residential and community spaces, the majority of which was assembled in just one day. The second project in Harlem, New York, is a 44,000+ square foot high rise multifamily project that will bring 51 affordable and market rate apartments to a historically disadvantaged community. Both projects are pursuing Passive House (PHIUS) and WELL for Residential certifications (early adopter). Together, these projects demonstrate Assembly’s transformative potential to meet urban development needs through advanced construction methods.
