ITZA

In Terms of Zone 'A' drawings and calculations

Our 3D laser scanning, measured and topographical surveys can be used to produce ITZA (In Terms of Zone ‘A’) drawings and calculations to support commercial property valuations, rent reviews, and lease negotiations.

Using accurate measured survey data, we calculate lettable areas in line with RICS standards, breaking down floor space into zones that reflect market value. 

Our outputs are clear, compliant, and tailored to your property type – whether it’s a retail unit, office, or mixed-use space. We work closely with landlords, tenants, and agents to provide reliable data that supports fair, evidence-based decisions.
