Answer 1

First of all a metal house especially one design with the material you use for Yeti would be very expensive.

Second of all it’s not practical because air and water have different properties when it comes to cooling or retaining temperature.

Third of all you do want some sort of temperature transfusion, sometimes you want sunlight to warm your home for example. Not to mention you definitely want and need air ventilation.
