The invention discloses a universal miniature habitable room structure formed by combining of circular spaces and belongs to the field of building design. The universal miniature habitable room structure comprises an upper top plate universal structure, a lower bottom plate universal structure, a front wall universal structure, a rear wall universal structure, side wall structures, a plate frame structure and bendable partitions for partitioning the habitable room spaces. The universal miniature habitable room internal structure is formed by connecting, interpenetrating and overlapping of the circular spaces formed in the mode that the double arms of a human stretch and rotate. According to the structure, adjustment in the aspects related to the house type can be conducted according to the requirements of dwelling personnel, the adjustment steps are simple and easy to operate, and a professional technician is not needed. A habitable room is divided into the multiple circular spaces, a plurality of semicircular spaces, a plurality of fan-shaped spaces and a plurality of spaces formed by combining of the circular spaces, the semicircular spaces and the fan-shaped spaces, and living functions such as sleeping, cooking, working, studying, dining and washing are integrated into the spaces, space waste is reduced as much as possible, various actions are smooth, action barriers are reduced as much as possible, limb collision is avoided, and smoothness and comfort of activities of the dwelling personnel are achieved to the maximum limit.
