Russia doesn’t really enjoy a load of sunshine and more often than not, the region is ridden with cold. So, when Peter Kostelov set about designing a home for his clients, he decided to leave out the windows! Called the Dacha’s Origami summer home, this all-white structure is made from sustainable timber and uses solar-heated water to its advantage. Complete with built-in bathing areas, a sheltered kitchen and loads of indoor dining and lounging space, this house uses a solar battery that heats the water used, and that’s not all. To keep his clients fit and trim, Peter also included pull up bars, a seesaw and a mini-gym!
