Questão jurídica principal
Whether an underground garage must be counted in the floor-area ratio under § 26(2) NBR.
Decisão extraída
The underground garage is not counted as gross floor area; the authority's approach was upheld.
Fundamentação extraída
A longstanding administrative practice excluding underground garages was made plausible by an official guidance sheet and by the approval of a similar local building regulation; the appellants did not show that this practice would conflict with the purpose of the floor-area ratio rule.
