Architectural Reading from Outside In: Double House

I honestly believe I've improved considerably in the structural analysis section. I'm much better than I was before. This time, the structure I need to analyze is one I've seen many times before: the Double House. Frankly, I really like this building; maybe it's because there's so much to analyze? Maybe.

This building uses load-bearing walls as its structural system. The dividing walls on either side and in the middle support the entire structure. The front and back of the building are mostly transparent openings. Because it doesn't receive light from all four sides, it receives more light from two sides. The areas without these openings are the bedrooms.

At the same time, from the outside, we can understand which areas are more private and which are more common; this is due to the high number of openings. Similarly, we can understand how the house is divided from the outside. The reason for the division is that there are two common areas on the property. The circulation between the houses is also created vertically, stacked on top of each other.
