To design a fascinating indoor environment while satisfying structural restriction.

In this bearing wall arranging structure 1 of a house, a pair of mutually parallel bearing walls 2 and 2 are erected by two sets in opposed positions (left and right positions in the drawing) for sandwiching a habitable space 3 as an indoor space. Two sets of projecting wall bodies 5 and 5 forming an almost U-shaped cross section are constituted by respectively joining outdoor side end parts of the pair of bearing walls by outer wall materials 4. The bearing walls 2 are adjacently arranged on outer walls so as to project by D to the outdoor side from the outer walls 6 being indoor-outdoor partition bodies.
