When and why would you use ITZA?
Space near street is more valuable - ability to attract passing footfall into the shop
85
how do you zone?
Halving back principle using 20ft (6.1m) as standard zone
→ half back each area until getting to Zone C / D, then remainder
→ 30ft zones used in Oxford Street, Bond Street and Scotland

‘in terms of best space’ using ‘headline rent’
Common allowances / discount - quantum discounts, shape e.g excessive frontage to depth, unusual shape, masked area, split levels
87
Why do you always zone a retails unit?
In general, the Market uses zone, so best to use in order to make comparisons
However, zone is not required and for departments stores and very large units, you may wish to value on an overall basis (once ground level exceeds 10,000ft)

WHat does RICS say about using m or ft for measuring?
Adopt metric units as standard
→ if Client requires imperial uits, they can be provided as supplemental information

107
How do you measure a return frontage?
Measure from the main frontage, then apply an additional % to the Zone A space
108
What issues might you come accross when measuring period buildings?
Fireplaces → viewed same way as heating apparatus. Exclude if protruding 0.25m into usable space
Mansard roof - a lot of space and under 1.5m

Use GEA for residential
Open for commercial, thought note we use GEA here too
