Are basements a good idea?
Considering this, what is the benefit of having a basement?
Energy Efficiency. A house with a basement has fewer directly exposed external walls. Wall and floor insulation are improved and the means of construction incorporates additional mass. The effect of this is that the building does not overheat or cool down too fast.
Herein, do you really need a basement?
A: Yes, basements can be a pain sometimes. And while some homes are better built without basements because of moisture issues, there are still millions of existing basements that need help. Homes like these needed a basement to keep vegetables from freezing and spoiling.
Older homes built with crawl spaces or rooms without basements supported slightly above the ground often have very cold floors. The absence of a basement can also indicate an insufficient foundation that can heave seasonally with frost. This is why I wouldn't buy an older home that has no basement.
