The present invention relates to a house without a wall. The house is vertically formed in a triangular pillar shape. In particular, the house comprises: a first rectangular plane structure for constituting a second structure, having wall surfaces commonly used for left and right walls, and constituting a building having a triangular pillar shape; a second structure having a gabled roof shape formed by the assembly of the first rectangular plane structure; and a connection material for assembling the second structure, and forming an overall building in an integral structure. Steel and cement are sequentially used, and thus a building having an integral structure is formed. By using such a common standard material, construction costs are reduced, and construction duration is reduced. Aesthetic impression of a building is ensured by three-dimensional spatial separation, and an internal space can be variously used. By means of a triangular pillar shape, safety with respect to a natural disaster or earthquake is reinforced. A room with the Korean floor heating system is ensured in an environmentally-friendly structure, and thus energy efficiency can be maximized in the house of the present invention as an agricultural and fishing village house.;COPYRIGHT KIPO 2017
