PROBLEM TO BE SOLVED: To obtain a building wind reduction effect equivalent to the case of providing a corner cut and a corner notch without changing the plane shape of a building, such as providing the corner cut or the corner notch for reducing the building wind in the building that may cause the building wind.SOLUTION: On a wall surface near a corner 1a of a building 1, preferably, fins 2 projecting from the wall surface are provided on both sides of the corner 1a to form a virtual wall surface 4. The starting point of the fin 2 may be from the top floor or from the middle floor, and is a building provided at least near the ground part, and a ratio (W/D) of a distance W from the corner 1a to the installation position of the fin 2 and a depth D which is a projection amount from the wall surface is preferably 0.5 to 3, and the depth D is preferably 6 m or less. The depth D of the fins 2 may be increased toward the ground by inclining the wall surface of the building 1 inward toward the ground.SELECTED DRAWING: Figure 1
