EVERY time he comes home, Leonardo DiCaprio is practicing what he preaches. The environmentally conscious actor has bought an apartment in Riverhouse, an eco-friendly building overlooking the Hudson River.

The purchase was confirmed Friday by Christopher Daly, president of Sheldrake Organization, the developer of the Battery Park City complex. Occupancy is slated for this summer.

The 264-unit condominium glass tower overlooks the river and a park, and boasts low emission paints, a 24-hour fresh filtered air system, a water treatment facility and rotating solar panels.

DiCaprio seemingly also will have everything at his fingertips. The David Rockwell-designed high-rise features an indoor 15-meter lap pool, media cafe, fitness center, landscaped terrace — and dog spa.

The building also will house the City Bakery and a branch of the New York Public Library.

DiCaprio has served on the board of directors of the environmental organization Global Green USA. He also owns a hybrid car and had solar panels put on his Los Angeles home.

The 33-year-old actor has won Oscar nominations for “The Aviator” and “Blood Diamond.” He is currently filming “Shutter Island,” directed by Martin Scorsese.

An e-mail sent to his publicist was not immediately returned.
