Questione giuridica chiave
Whether the basement and ground-floor areas of the hang-site buildings could be excluded from floor-area ratio calculation in the later permit procedure.
Decisione estratta
No. In the later permit procedure a fresh calculation over the whole parcels was required, and ground floors and the annex areas had to be fully counted toward the floor-area ratio; the partial-counting privilege applies only to qualifying underground floors.
Motivazione estratta
The court held that the special partial-counting rule for floors partly above terrain is, by settled administrative practice, limited to underground floors. Ground floors used mainly for living space influence the density of the quarter and must be fully included.
