Frequently asked questions
What is the difference between gross and net area?
Gross area includes wall thickness and the flat’s share of building common areas. Net area is the space you actually use inside. Listings usually quote gross; net reflects livable space.
How large is the shared-area share?
It is typically 15-30%. Buildings with elevators, wide stairwells and amenities lose more; low-rise buildings without amenities lose less. Check the project’s unit schedule for the exact figure.
Which should I use when comparing?
Whichever you pick, use it consistently. Two equally priced flats with 15% and 30% shared-area shares have clearly different net prices per m². Enter a price here and the calculator shows both.
