A building structure includes a building unit, such as a mobile home, house trailer, motor home, prefabricated building, hut or shed, duck blind, platform, or dock. There is also provided a shell, preferably of a resilient plastic material, which shell is of such size and configuration as to underly the building unit and provide a base upon which the building is supported. The shell defines a space between itself and the building unit. This space is substantially entirely filled with an insulating foam filling material in the shell. That is, according to the method of construction of the present invention, a dished shell with a hollow interior is placed at a selected building site in a concave, upward condition, which shell constitutes a main part of a foundation for the overall building structure. A building unit of the type described is moved into overlying relationship with respect to the hollow dished shell such that the hollowness of the shell defines a space between the shell and the building unit, which building unit constitutes that part of the building structure above the foundation. The space between the shell and building unit is then substantially entirely filled with the plastic foam material.
