Accurate area measurement is a vital step in the valuation, rating and marketing of property.
What is area measurement?
Area measurement is the means of determining the size of a building or plot of land, and is the starting point for any property negotiation.
It is essential for both parties to reach an agreement in advance on the basis for which the property in question will be measured. The Royal Institution of Chartered Surveyors (RICS) Code for Measurement Practice sets out a system of guidelines for area measurement to remove the potential for disputes at this important stage.
Two standard metrics are used in the measurement of area: gross internal area and net internal area. To find out more about area measurement and how Technics can support your next project, call our Project Management Team on 01483 230 080 or email email@example.com.
What is gross internal area?
To calculate the gross internal area of a property, measurements are taken on each floor level, up to the internal perimeter walls. This can include:
- Areas occupied by internal walls and partitions
- Chimney breasts
- Vertical ducts
- Other internal projections
Common exclusions to gross internal area include:
- Open balconies and fire escapes
- Minor canopies
- Areas with less than 1.5m of headroom (other than underneath stairs)
What is net internal area?
Net internal area is the useable space within a building. Measurements are taken up to the internal face of the perimeter walls on each floor level – but crucially, only areas that can be used for a specific purpose are taken into account. Net internal area can include:
- Perimeter skirting, moulding, or trunking
- Built-in units or cupboards in useable areas
- Entrance halls and corridors
Several factors are excluded from net internal area surveys, including:
- Plant rooms
- Stair and lift wells
- Any areas controlled by external authorities
- Internal structural walls
- Spaces occupied by permanent air conditioning, heating or cooling apparatus
- Areas with less than 1.5m of head room (should be excluded and shown separately)
