which rooms are not included in carpet area?
The common areas are also not included. Common areas are the lifts, staircase, lobby, play area etc. The actual area a buyer enjoys for purposes of housing is the carpet area. Let's say, carpet area is the space available to you, and includes the bedroom, living room, kitchen, balcony, toilet, dining area etc.
uhm like rooms that arent supposed to have carpet?
uaually the bathroom and kitchen are not included unless you request it , same with closets you need to specify for proper pricing and footage of materials
