Have a look at my favourite architect alberto campo beaza from spain because of your interest in the cave and hut ;)
Enjoy the journey

I'll check it out...I don't know if I have the money to engage Alberto though...Well, actually I KNOW I don't have the money... :)

My mate is a good guy and as he also owns the building company will steer me right. I'm meeting hims today for a site visit as it turns out.
