    Frequently asked questions:

    What is the RICS Code of Measuring Practice?

    The purpose of the Code is to provide succinct, precise definitions to permit the accurate measurement of buildings and land, the calculation of the sizes(areas and volumes) and the description or specification of land and buildings on a common and consistent basis.

    Why get an area reference survey done?

    It may be required for valuation, management, conveyance, planning, taxation, sale, letting, or acquisition purposes.

    What is the difference between GEA and GIA?

    GEA – Gross External Area is the area of a building measured externally at each floor level.

    GIA – Gross Internal Area is the area of the building measured to the internal face of the perimeter walls at each floor level.
