Because the grounds surrounding 3-story walkups, front and back, belong to all the families living in the building, they cannot be considered private. The grounds in the front of the unit are also adjacent to a public street. For this reason I would categorize the grounds in front as semipublic space. The grounds at the rear of the unit are also not as-signed to individual families and the rear of the units are often used for parking. In such a case, the grounds at the back would also have to be considered semipublic. It is, however, possible to modify the design of the rear grounds to make some of the areas private and the remainder semiprivate, and I will demonstrate how to do that shortly.
