PROBLEM TO BE SOLVED: To provide a building capable of improving workability of construction work at a construction site and improving thermal insulation effect. SOLUTION: This building includes columns 9 forming a skeleton of the building, existing walls 10 forming an indoor space of the building, a vacuum heat insulating material 11 arranged in at least a part of an indoor side face of the existing wall 10, and a heat insulating wall 8 having a plurality of furring strips 12 fixed on at least a part of the indoor side face of the existing wall 10 and piercing prevention plates fixed on the indoor side of the furring strips 12, and is arranged such that the furring strips 12 cross a plurality of columns 9. Consequently, since dimension of the vacuum heat insulating material 11 can be decided without relying on the dimension between the columns 9, the number of kinds of the vacuum heat insulating materials 11 having different dimensions is reduced, the number of use of the vacuum heat insulating materials 11 by mistake at the construction site is reduced, and the number of opportunities for using the vacuum heat insulating material 11 erroneously is reduced so that workability of the construction work can be improved. Since the furring strips 12 on the whole are not fixed on the columns 9, the occurrence of the heat bridge phenomenon in which the heat generated indoor and outdoor parts is transferred through the columns 9 and the furring strips 12 is prevented, and thermal insulation effect of the building is improved.
