The star of "Titanic," "Gangs of New York," "The Aviator" and "The Departed" bought a unit in the new eco-friendly Riverhouse development on the waterfront in Manhattan's Battery Park City, said an article posted on New York magazine's Web site and due to run in the next issue of the publication.

The condos in the soon-to-be-completed 264-unit highrise have been LEED-certified gold, which is the second-highest rating for green buildings, the report said.

DiCaprio was seen riding his bike several times to the site's sales office, but his publicist would tell New York only, "Riverhouse is a prime example of how green technology is both accessible and achievable for new residential developments -- it is a groundbreaking building."

People who live in the building will breathe twice-filtered air and use solar-powered energy. Builders are using only non-pollutant materials and finishes.

The highrise also boasts a pool, yoga studio, children's playroom, rooftop green landscaping, rotating photovoltaic cells that follow the trajectory of the sun, a media cafe, free bike storage and a dog spa, Riverhouse representatives said.
