"an array of plants and flower vases"

Architecture Domus Magazine has a series detailing unusual highrise houses in Tokyo. This edifice by Ryue Nishizawa attempts to combine the beauty and health aspects of a garden with a high rise living and taking advantage of the tiny footprints of property which are available downtown:

"Wedged between two tall buildings and invisible from the main road, the narrow Nishizawa building insists on maintaining its confidentiality via an array of plants and flower vases that screens it from the gaze of passers-by. It might easily be mistaken for some sort of mysterious vertical garden."

Beautiful as it is, there are a few negatives. A resident has to choose between storage space and a guest bedroom and it's very close to next door apartment building, whose windows overlook each floor. Even with those plants, privacy does not seem to be a priority.
