House Within a Greenhouse: Your Own Private Bio-Dome
The Naturhus is a design concept that creates an energy efficient micro environment by placing a smaller house inside of a greenhouse. For colder climates this creates a way to extend the benefits of warm weather into the cold months. The green house keeps the interior temperature comfortable and also lets residents grow a variety of plants that couldn't usually survive the Swedish seasons. This plus a combination of wood burning ovens and a hot water masonry heater keep the electric bill about 50% less than a traditional home.
