Our aim is to provide the highest quality floorplan area surveys provided in our unique Rentable Area Survey format that complies with the Method of Measurement as set out by the Property Council of New Zealand (formerly known as BOMA surveys).

A Rentable Area survey is a measured survey of the floor space for leasing purposes and is often used to assist with rental calculations or a property valuation. We are experienced in properly determining the rentable areas is essential to safeguarding the interests of both tenants and owners alike. A small miscalculation in the area of a property can have significant impact when multiplied over the course of a 10 or 20-year lease.
