The work of Dutch design studioDenieuwegeneratie and their amazing work on the Dutch Mountain House. The underground house is embedded beneath a mound of earth at a Dutch nature reserve.
The large glass facade allows the sun to warm the concrete shell. The thermal mass keeps this warmth and cools the house in the summer. The wooden cantilever regulates sun and is the only visible architecture in the landscape. The open structure of the house is filled in with a light set of rooms, giving it a flexibility to grow together with its owners.
