What the architect invented, was to put the rectangular courtyard at an unusual oblique anglerather than a right angle. Locating courtyard in this way makes spaces around the courtyard can have enough room to stay, and be chained each other directly at their corners, without aisle.
Otherwise, inside spaces of the house would be divided into several parts, when the courtyard is located on the middle of the site whose width is limited, and unified feeling of the house would be spoiled.
This arrangement creates not only sense of unity of the spaces, but also several specialized places to each purposes. In addition, each place in the house is facing to the courtyard, which is separated enough from neighbors’ houses, and you can enjoy complete privacy and beautiful blue sky.
