In the fixed area test, the areas of these three types of houses are for a person, for a couple and for a family in order from small to large. The total area of each house and the area of each room in a house are fixed.

In the fixed boundary test, the experiment first fixed the boundaries of each type of room, so the total areas of all rooms in the same type are the same.

The depth graph was drawn for each floor plan, and the depth of each house was used as a parameter to analyse the generated results. The figure shows the topological relationship of the internal space of the houses in the form of a depth graph.

In this section, the experiment will explore the relationship between the graph and the floor plan by changing the weights between the nodes in the directed graph. Three floor plans with different areas and graph were tested.

One of the case tests is Correa, Charles’ project named Kanchanjunga Apartments. The adjacency graph is divided into two parts, corresponding to the upper and lower levels.
