Damien Hirst Dabbles in Homebuilding.    Hirst's "Physical Impossibility of Death in the Mind of Someone Living" (Sotheby's/PA) Artist Damien Hirst, known for, among many other things, suspending dead animals in formaldehyde, is also considered to be the world’s richest artist (he’s reportedly worth over $300 million). He’s investing some of that money in the development of 500 new “eco-houses” near North Devon, on the southwest tip of Great Britain. The residences, which will feature rooftop turbines, solar panels and sophisticated insulation, are slated to break ground early next year. One of the firms working on the drawings is London firm MRJ Rundell + Associates, whose founder Mike Rundell told a North Devon newspaper of Hirst “He has a horror of building anonymous, lifeless buildings. He wants these houses to be the kind of homes he would want to live in.”
