In this villa, when it was being built, there were some arguments with my father over the thickness of this wall. The thickness of walls generally comes in several types, such as: 12cm thick brick walls, 24cm thick brick walls, 37cm thick brick walls, 49cm thick brick walls.
Generally speaking, the walls in the north are thicker, but under Li Yu's strong insistence, the buildings in the base were built three times thicker than usual, almost 70cm!
You should know that even in the north, even in the peripheral regions, it's only 50cm thick, but Li Yu insisted on building the walls to 70cm.
This is seen as very exaggerated in the eyes of people from the south.
Though it occupies some area, the benefits it brings are very clear: insulation against cold, heat separation, warm in winter and cool in summer.
The thickness of the walls has only one downside, it occupies space, but the rest are all advantages.
