The invention relates to a movable changeable building which is composed of a function module and a 
system module. The 
system module comprises a changeable building 
structure system, an intelligent mechanical 
control system, a hidden type inflation heat preservation wall 
system, a changeable furniture lamp system, and auxiliary systems including a power system, a 
power consumption system, a water system, an indoor environment 
control system and a cloud network system. The changeable building 
structure system is a 
steel frame structure based on a universal automobile 
chassis. The changeable building 
structure system comprises the 
chassis, a main structure and a changeable component. The main structure and the changeable component are located on the 
chassis. The changeable component is located outside the main structure. The changeable component is connected with the main structure through a 
hinge joint and is provided with a hydraulic device, and opening or closing is achieved through the hydraulic device. The movable changeable building has the advantages that the movement flexibility and spatial changeability can be achieved, and the effects of being comfortable, safe, capable of saving energy, 
environmentally friendly, automatic in control and the like are achieved by optimizing and integrating all the auxiliary systems.
