Villa Kogelhof, Noord-Beveland, the Netherlands
Like something out of a James Bond film, the futuristic Villa Kogelhof sits on a 60-acre estate surrounded by more than 70,000 trees and a large pond. The villa is impressively self-sufficient, helpful given its location in a protected ecological area. It generates its own energy, heats its own water and recycles its own rubbish thanks to a number of innovative building elements.
