Prefab house is one kind of temporary office or living building. The usage is just like a house, and the lifespan(about 4-8 years) and strength is less than a normal house we see.
So why we need to use this kind of house? When we start a project, the temporary living and office need to be done in advance. People will choose a way of less cost to fulfill their need, so prefab house is the best choice.
Normally prefab house is installed with light steel structures and panels. The panels are divided into roof panels and wall panels with windows and doors.
About installation, one standard 3.6*6 meters house can be done in 2 hours by 4 skilled workers.
About recycling, it can be reused for once.
