TNV (Technical and Numeric Variation)
Written and verified by Struqt’s registered architects · Last verified July 2026
Address-specific overrides applied on top of the zone's default rules. TNVs change the effective height limit, setbacks, site coverage, or minimum lot for your particular parcel — a step every designer must check before sketching anything.
