103-year-old Clingstone mansion set on a rock island in Narragansett Bay is owned by Boston architect Henry Wood. Even though the all-wood home with 360-degree view of the ocean is quite old and rough it’s still warm and beautiful. Three stories tall house features 23 rooms, 10 of which are bedrooms. Even though the house is quite expensive to maintain because of it’s made of wood, it still use modern technologies to cut pay bills. Solar panels heat the water, and a wind turbine on the roof generates electricity. Rainwater is collected in a 3,000-gallon cistern, then filtered, treated and pumped through the house for cleaning purposes. Besides that, Clingstone house use the latest technologies in filtering seawater and the most up-to-date composting toilets. [via freshome, NY]
