Assembly builds urban buildings.

Our buildings are customizable, low carbon, and high quality
to meet the needs of cities.

Customization at scale.

Our evolving catalog of interior finishes and facades results in a unique project every time.

A building system that rises to the occasion.

Assembly buildings can adapt to any site. They need not be orthogonal and they thrive in dense urban contexts.

Your units, our system.

One mod makes a studio, two makes a one bedroom, three makes a two bedroom, and so on.
Modules sizes are custom per project, making your units endlessly customizable.
