If you look carefully at a given unit/phase architectural drawing you will see a floor plan and then exterior elevations. To the right you will see notes and it will delineate for that particular unit the upper and lower boundaries. Typically it is shown as the finished undecorated surface of the floor ( for instance third) and the interior unfinished surface ceiling of the same floor. This is the first time I have looked at any drawings for Kidani but I would say the language is very similar across most developments on property, as most of the unit drawings are done by the same company.
