Gross Built-Up Area vs Net Usable Space & Loading Ratio

Loading describes the gap between marketed sale area and usable area, but definitions and measurement methods can differ across documents and projects.

Request a dimensioned plan and a statement of what the quoted area includes, then normalize rooms, circulation, terraces and common-area allocations before comparing price per metre.

Obtain the project's definitions of gross and net area, then a schedule showing each room, balconies, light wells and included common space. Do not assume one loading-ratio definition applies across developers or even across phases of the same project.

Test the dimensioned plan with furniture and storage, and compare cost per usable metre after normalizing finishing and handover. Ask an engineer to review material differences and identify the drawing or area schedule incorporated into the contract where possible.

Turn the finishing specification into an inspectable schedule: brands or equivalent standard, electrical and plumbing points, waterproofing, doors, windows, floors, cooling, and explicitly excluded work.

At handover, record defects with photos, location, date, and the party responsible for correction. Do not sign final acceptance until you understand how it affects repair or compensation rights.

Build a three-column check: what is documented, what has only been said, and what still needs independent verification. If an undocumented point is the main reason to buy, pause until evidence exists.

Stress-test a less optimistic case: handover slips, a variable cost rises, or you need to sell early. A sound decision remains manageable when events do not follow the sales presentation.
