Our house is three levels, plus a full basement. All have the same footprint: 20 feet wide by 70 long. Each floor has a side and rear bay and the tower bay; the bays add a lot of extra space and light. Because this was the “builder’s house,” a display model, it is wider by two feet than the others on the block. Also, most unusual, it has oak parquet throughout the first floor–all the way back to the kitchen.
To get oriented to the floorplan, take a look at the first level. The red dot represents the position from which the photo above was taken (from the main stairs landing down to the entryway). The blue dot represents the position from which the second photo was taken, offering a straight view from the front of the first-floor bay through the living room, the music room, then through the pocket doors into the dining room.
