To connect water and sewage to the prefab house, utilize the valves at the backside, connecting the water inlet and sewage outlet with appropriate pipes

The unit is designed for outside usage and can withstand a heavy snow load. The unit is safe before the snow reaches 6.6ft high on the roof.  However, it is recommended that take off the snow in time and don’t stay inside in extreme weather conditions (storms, tornados, hurricanes, floods, blizzards, etc)

The wallboard is composited with foam in the middle, so you cannot screw in the wall. You will need to use self-adhesive hooks for hanging, and the load capacity is depending on the hook.

Technically, no. There is still a gap between the two units.
