Abstract: In a house having a standard two-story building height, an inner living space is provided, which gives a feeling of spaciousness and openness. A house includes: a first floor; a second floor; a higher second floor as a skip floor positioned substantially a half story higher than the second floor and being led from the second floor; and a gable roof provided above these floors. The higher second floor is provided along a gable end wall of the gable roof on at least one side to spread across a full width of the gable end wall. An upper area of the higher second floor is integrated with an attic space under the gable roof.

Abstract: A ridge is directly supported by a ridge supporting post that is erected on a floor plane of a floor right below a gable roof to provide a stable building frame having a pentagon shape in front view and furthermore to realize a beamless space where no lower chord member such as a roof beam extends above the floor right below the gable roof. Also, a tall window extending continuously toward the vicinity of the ridge is provided between the ridge supporting post of a gable end wall and each of gable end side sub-pillars erected on both sides of the ridge supporting post. Thus, a living space gives a feeling of spaciousness and openness in spite of a compact appearance of a building.
