An optimum design approach for a group of buildings is proposed. Any two buildings closely situated may result in serious damages simultaneously by a natural disaster because of its spatiality. Due to this, it is important in optimum design of a group of buildings to treat suitably the correlation of loads caused by natural disasters. So far, it seems that expected total cost is of main concern, but the spatial correlation of loads can be dealt only with more than the second moment of total cost or even distribution function of total cost. Also important is the situation with which owner faces and his/her attitude toward building risk. The consequences of damages of a group of buildings caused by natural disaster may be much more serious than just the summation of each individual building. These affairs should be properly considered in design of a group of building. In this paper, we propose one rational approach, and its characteristics and consistency are confirmed through three simple but illustrative examples.
