- Remove a ceiling tile
- Try and get behind the partitioning
- Inspect the basement or first floor to see actual built width
- Scale from floor plans (having undertaken some on site check measurements)
What is included in a Net Internal Area (NIA) measurement?
- The usable area within a building measured to the internal face of the perimeter walls at each floor level. - NIA covers all areas which are used for a specific purpose.

- Kitchens
- Built in cupboards occupying usable area

What is the internal eaves height?
The clear height between the floor and the lowest point on the underside of the roof e.g. at the eaves
What is the site depth?
The measurement from the front to rear boundaries
What is the shop depth?
The measurement from the notional window display to the rear of the retail area, including the thickness of the display window
What is the built depth?
The maximum external measurement from the front to rear walls

What is the difference between plot ratio and site cover?
Plot ratio: gross floor area of the property divided by the site area
Site cover: the building footprint expressed a percentage of the site area
What should be done before calculating the site area on Promap?
Check the boundaries on site with an OS plan and / or Land Registry title document
What could be used to measure the boundaries whilst on site?
Trundle wheel
