Abstract:
The building structure comprises a pre-existing single house structure having a peaked roof with an opening therein, a separate later built prefabricated dwelling unit positioned in the opening in the peaked roof of the house structure and extending outwardly away from the house structure and supported in the opening in the house structure by bearing walls of the house structure or separate support structure or by both which dwelling unit includes access either from the exterior or interior of the house structure or both, and which prefabricated dwelling unit includes parallel spaced apart side walls including a truss therein extending the full length of the side walls. Expansion of the single story pre-existing house structure is accomplished by constructing a prefabricated dwelling unit at a remote location shipping the dwelling unit to the site of the house structure, cutting an opening in the roof of the house structure placing additional support structure for the dwelling unit inside or outside of the house structure in either spaced relation to, adjacent or within bearing walls of the house structure, physically lifting the prefabricated dwelling unit into position in the opening in the peaked roof of the house structure and extending outwardly therefrom and supporting the prefabricated dwelling unit on one or more of the bearing walls of the house structure and the separate support structure.
