Cellar at house building

To much ground surface of the cellar for a usefull usage. New ideas to use the place below the house better. New demands which will be actual in the next decades.

Pressure-watertight cellar for a fixed price
	I came on the exhibition stand as a fan of the cheap method without cellar. After some discussions about the offer I already wanted to build with a cellar below half the house.

Cellar or foundation
	When I came along one year ago to the house planning, I still thought a cheap foundation and no cellar. However, with the progress of the planning everything looks completely different.
