Sectional diagram: My intention is to use this diagram to discuss the programme of the first floor. I'm using the three cross-section cuts to indicate the frame of the house, and use different color codings to convey the different functionalities of each room.
The blue rooms are the ones that I deemed to be more "public," meaning they can be accessed from more than one entrance.
The red rooms are the ones that are more "private," which include the mainden's room, which later became Ms. Schroder's sleeping room, the bath room, and the architect's studio, which orginically was intended as a garage.
