Net and gross area: why price per square metre differs

Price per square metre becomes misleading when one listing uses net area and another uses gross area. Ask how the advertised figure is defined and whether balconies or common-area shares are included. Use the same measurement basis and check the layout against the physical unit.

Practical steps

1. Keep a plan showing room dimensions and the measurement units used
2. Calculate comparable prices using the same type of area for every option
3. Resolve material differences between advertising and documents before making a firm offer
