Detached building [BPD]

Details
Category: terms
Hits: 405

The building may be within a block, but it is not attached to any other building. This applies to buildings whose neighbouring buildings are spaced apart a distance equal to or more than 4% of the height of the lower building. Where  buildings are spaced closer than this, but not attached, they are considered to be adjacent.
