Seems there had been quite a bit confusion on the term loading.

Loading is not a standard term and hence can NOT be calculated using a formula.

Loading is a commonly used term in RE and hence interpreted differently by different people and in different region.

The root cause lies in the concept of apartment pricing and greed of builders.

In India, Apartments are not sold by CARPET areas, which can be easily measured without any grey areas.

To fuel the greed of builders, they innovate a term called Super Area or Saleble area. There is absolutely no formula to calculate Super Area or Super Built Up Area.

At the beginning, almost 20 years back, it used to be simple ... total foot-print of the building divided by number of flats in each floor used to give super area. In case the flat sizes are not equal, then an approximate proportion used to use.

But the builder were not happy.... so they keep on adding an imaginary percentage on top of the above number ... on the pretext of common facilities like guard house, pump house (club/swimming pools are very recent). Traditionally this additional percentage increase used to be called as LOADING. It can be anything from 10% to 40%. Mumbai, Ahmedabad, Surat has a very high loading. 30% loading is generally considered normal.

There is absolutely no logic on the above percentage. It's just the whim of the builder... you take it or leave it.

Recently, some people use loading to define density of the project... simply no of flat per acre.

Since there is no formula, you yourself need to measure the size of key areas (like hall, dinning, bed room, kitchen) and then decide. Two similar size flat can have significant difference in key areas or REAL USEFUL AREAS

Hope this clarifies. If you want to comment, please comment practical aspects, not some bookish formula
