Famed progressive thinker and Google co-founder Larry Page is working out the details as he plans his new 6,000-square-foot, eco-friendly house on an acre sized lot in Palo Alto. The Google house will include solar panels, materials that do not emit toxic chemicals, and paving that allows the rain to seep through, which is a major plus in California, where water planners are looking to fill up aquifers.

The exterior of the house will have zinc cladding and plenty of enormous windows, including a wall of sliding-glass doors in the back. Page is also working with an arborist to replace some trees in poor health with those that use less water.

Building this eco-house adds to Page’s forward thinking work in areas such as alternative energy companies (he was a major investor in Tesla Motors, which developed the Tesla Roadster, a 220-mile (350 km) range battery electric vehicle.) Larry Page, with the help of Google’s philanthropic arm, promotes the adoption of plug-in hybrid electric cars and other alternative energy investments.
