Abstract: A single, bi-level or multi-level structure is built having a foundation; spaced, parallel side walls extending upwardly therefrom; a roof connecting the upper edges of the side walls; and a horizontal partition extending between the side walls divides the structure beneath the roof and is initially left open, through which a mobile home is subsequently introduced into the structure to complete the lower level. The distance between the side walls is preferably greater than the width of the mobile home, and an inner wall or partition extends the length of the structure between one of the outer walls and the mobile home, whereby storage space, a separate entranceway, and a flight of stairs to the upper level may be provided. The mobile home itself includes a special floor plan and a higher ceiling space than in conventional mobile home units, into which a sprinkler system and heating and air conditioning ductwork is installed.
