Land area refers to the size of the land the property is on, whereas the built-up area is the size of the property where space can be used – such as bedrooms, bathrooms, kitchens etc. For non-landed properties such as condominiums and apartments, land area is usually not used. And for properties that have multiple storeys, it will be larger than the land area. This would help you identify which is which even if your developer may have used another term. If can typically be found on the front plan or brochure.
