Wak Hassan is designed with the mind of making the house seem as airy and open, while still providing a sense of privacy. White walls and large windows are used to give the effect. On the facade of the house, the front-facing window shows a part of both the second floor and third floor, revealing the partition between the two floors, as well as a black pillar. This gives the house a unique look, as well as allow light to enter the second floor from the front of the building.
The interior of Wak Hassan is mostly white with light wood accents, giving a soft, peaceful atmosphere. The bathrooms of the house is tiled with a black-lines-over-white-base pattern, adding an aesthetic quirk to the house.
