This is Koby Cottage by Garrison Architects in Albion, Michigan. The two-module structure of 1,100 square feet was assembled in about 48 hours and finished as a guest house for families to use while visiting their children at the non-profit Starr Commonwealth.

Koby Cottage has a rooftop deck, a contemporary interior finished with light wood, and an exterior clad with weathered cor-ten steel.

It’s the first structure built using the Kullman Frame System developed by Kullman Buildings Corp., an entity wrapped up with XSite Modular and the much discussed Atlantic Yards prefab project. KFS is a light, welded, factory-produced frame chassis similar to the trellis frame on a Ducati motorcycle.

KFS has hollow tubular steel that supports large window openings and cantilevers in the Koby Cottage, according to Garrison Architects. The same frame can be used to stack modules up to twelve (12) stories high using a patented connection system. Here’s a video of the site assembly.
