Tyra Banks has followed Leo DiCaprio's lead, having purchased a bamboo-floored pad in the Riverhouse building [1] on New York's west side overlooking the Hudson River.

Meanwhile, Leo's Gangs of New York castmate, Cameron Diaz, is said to have stopped by to check out the building on a recent trip.

Riverhouse runs on solar-powered energy and was built with non-pollutant materials. It comes with a 24-hour fresh-filtered air system, media cafe and green rooftop landscaping. Check out what the "green house" looks like below!
