The other thing is maintenance. Any building will eventually collapse if not properly maintained. Second law of thermodynamics is that entropy always increases.

The other thing is maintenance. Any building will eventually collapse if not properly maintained. Second law of thermodynamics is that entropy always increases. The only way to decrease entropy in a closed system is to open the system and extract the entropy by some means. For a house that means cleaning, replacing broken and damaged parts, painting and general maintenance. Without releasing the entropy from time to time even a home made of solid stone will eventually weather away to ash and dust.
