Cabin Soluções Usiminas. A quick-assembly house inspired by Scandinavian design: both the purchase, made online, and the speed with which it is built dictate the entire process. With pieces weighing a maximum of 60 kg each, it is ready in 20 days and, although it can be moved from one place to another, it is a construction that will last a lifetime. Compact, it is made of metal structure, still frame and glass and has two floors covered in pine.
