The shape of the house is not that important, it depends on the surrounding environment and the layout of the house.
Founder's house, the surrounding environment is unfavorable, and the internal pattern is improper, which will be very poor. If the house is not square, the surrounding environment is favorable and the internal layout is proper, it may be good.
To put it bluntly, the shape of the house is not the point. Every link needs comprehensive consideration. For example, Mongolian yurts are round, and most Mongolians are a little short and fat. Mongols used to be strong!
