Charles Sacilotto thought about the idea for several years before contacting architect Bengt Warne who built Sweden's first nature house in Saltsjöbaden in 1976.
Warne helped him design the greenhouse and the waste storage facility which allows the Sacilotto family to use their own human waste as soil fertiliser for the large variety of vegetables which thrive in the hothouse atsmosphere.
"It's much more than a house, it's a philosophy to use all the resources which nature provides us."
A large tarpaulin protects the roof of the greenhouse from letting in too much sun and the family can always open a few windows to cool the atmosphere in the hot summer months. Charles Sacilotto says that it is never hotter than 28 degrees celsius in the house, which was built in the 1950's and has been renovated completely by the woodwork enthusiast.
Future plans include an economically viable solution to harnessing the warmth generated by the greenhouse in the summer for use in the cold winter months.
