In November, Jetson Green featured a post by one of their sponsors, Envision Prefab.
Envision Prefab ... is bringing container architecture to a new level by creating complete modular housing out of these frames.
The home starts with the basic cargo containers. Factory technicians mark out the windows, doors, mechanical, and plumbing vents and cut through the corrugated metal walls. The interior wall is completely removed, and the containers are braced to prevent any deflections.
See the post for photographs of the construction sequence.
