As a general rule, for a 24-square-foot building, it will take a four-person team 5 to 10 days to assemble the floor, the structure, the walls, the doors and windows as well as the roof. This is obviously a lot faster than for a light 2”x6’wood frame building. This is possible because of how we prepare our kits at the factory. Once on site, you simply have to put it together! The measurements and intricate cuts have already been made by the Boreal team.
