2. Residential Common Area
Area shared by multiple households, such as hallways, stairs, and elevators.
3. Supply Area
Exclusive Area + Residential Common Area. This is the standard used for sales listings (e.g., "34 Pyeong Type").

The percentage of exclusive area relative to the supply area. Apartments are usually high (70-80%), but officetels are lower (40-50%) due to more common areas.
