Wearing khaki pants, T-shirt and hard hat, the 43-year-old actor walked through the house Tuesday, pointing out its many "green" features, including blue walls treated with a nontoxic repellant for mold and termites.
"There's light coming in from all sides and a lot of ventilation," said Pitt, standing in what will be the living room. "A lot of thought has gone into this house."
The three-bedroom, single-family home is the first of five slated for the Holy Cross section of the Lower 9th Ward based on the winning design in a competition launched in 2006 by Pitt and the environmental organization Global Green USA.
The house is also designed to relieve some of the burden of bills for low-income families, the predominant residents of the Lower 9th Ward before Katrina. Pitt said electric bills will be cut by 75 percent; water use, by half.
Pitt and his partner, Angelina Jolie, purchased an early-1830s masonry mansion in the city's French Quarter for $3.5 million in January.
"There's so much of this culture here that is unlike any other city that we have," he said. "It's a feeling that I can't quite explain, but I love being a part of it."
He also expressed disappointment at the slow pace of recovery in much of the city.
Developers broke ground on the home in May and should be finished in the next few months. It will serve as a model home and visitor center while other houses are constructed. Plans also call for an 18-unit apartment complex and community center.
Global Green plans to sell the homes, giving preference to former residents of the neighborhood.
