The various heights of the rooms destroy any sense of distinct floors when one first visits the Villa Muller, but when looking at a plan, one can categorize the rooms by floors. At the basement level, which is half-embedded into the hillside, there is the garage, boiler room, staff quarters, and storage space. The main level consists of the primary living spaces, such as the living room, dining room, kitchen, library, and Mrs. Muller's boudoir. The next floor contains the family's private rooms, including the master bedroom with flanking his-and-her dressing rooms, a guest room, the children's bedroom and playroom, and the maid's quarters. Culminating this series of floors is a room that was used for attic space and a Japanese-style breakfast room with doors that open onto the large rooftop terrace. This rooftop terrace is the largest of several terraces and provides the framed view of the Prague castle. Within the Villa Muller each room is distinct and defined, yet there are smooth and subtle transitions from one room to the next. On the main floor, transitions between each room require a person to ascend or descend a few steps, turn a corner, or pass through a short corridor to reach the next room.
