This, at this point in time, is what I would call a great piece of architecture. It is located in Kent in southeast England designed by architect Richard Hawkes. It is the first house in the country that has been certified for Passive House performance, utilising DuPont's Energain insulator panels helping to absorb heat and release as the temperature rises and drops outside. It also uses a  parabolic arc framing the house known as a Catalan vault, in which three layers of clay tiles have been lain, supporting itself completely. They also have used triple glazed windows and solar panels for all of their heating, in turn generating them not only enough energy and heating to support themselves but also enough to sell back to the grid, making it very eco-friendly and efficient to live in.
