Wind pressure models for wind tunnel experiments used in structural design of high-rise buildings are often reproduced with deformation while the effect of the detailed shape of the facade on wind force measurement is unknown. The balcony is one of the shapes that are often reproduced deformed. This report is a case study that confirms the effect of the following three points on the layer wind force. (1) difference in balcony reproduction, (2) presence / absence of balcony measurement, (3) difference in measurement point arrangement. When the balcony shape is not reproduced it gives an overvaluation to the mean layer wind force and its standard deviation, and when reproducing the balcony as volume it gave underestimation. The wind force borne by the balcony itself was small. Also, in the case where the measurement point is placed on the inside of the balcony and the case where the measurement point is arranged outside the balcony, the influence on the layer wind force was minor in either case.
