Imposing Earth House

I came across Peter Vetsch's design-earth house. It's an amazing design and distinctive concept. It makes full use of natural environment and leaves less carbon footprint. A man named BRIAN said like this (not original remarks), when man first walked the earth, they lived in cave and underground houses which provided safety. It seems that we have come full circle with the implementation of earth homes in today’s society. The ecological benefits are simply undeniable! Absolutely right!
I think architecture which has close realationship with environment can get more and more attention.
Our company has created many architectural renderings or architectural visualization and 3d walkthrough for modern architecture which are also very nice, but less imposing compared with earth house.
