TNV (Technical and Numeric Variation)

By Struqt’s architects · Updated June 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.

What it means for what you can build

A TNV overrides the zone's default numbers for your specific parcel, so always check it before assuming the standard height, setback or site-coverage rules apply.
