How many square meters is the best per capita housing area in Feng Shui?

Feng shui? Only consider the climate and physiological characteristics of people in China, and take a family of three as an example: 1. The lighting in the living room is at least 4 (south) *5, the master bedroom is at least 3.5 (south) *5, the second bedroom is at least 3 (south) *3.5, and the study or activity room is at least 3.5*5. Secondly, the ventilation is 5*2 (north-south direction) and 2 (north-south direction). Thirdly, everyone's mental space is 1.75*2*2. The total demand for reasonable housing layout is: (4+3.5+3.5+3) * (5 * 2+2)+(1.75 * 2 * 3) =189 (usable area) square. 63 square meters per capita! If the building area is calculated, it can be converted into a pool ratio.
