LOS ANGELES, CA (AP).- Billionaire Ron Burkle has snapped up Frank Lloyd Wright’s landmark Ennis House at the relative bargain price of about $4.5 million, the building’s sellers announced Friday. Ennis House Foundation chairwoman Marla Felber said Burkle, a supermarket tycoon, would continue rehabilitating the 1924 concrete block home, on which the foundation had already spent $6.5 million for repairs. Burkle is also the owner of the so-called Greenacres Estate in the Benedict Canyon section of Beverly Hills, which he bought in 1993. The estate, like the Ennis House, is listed in the National Register of Historic Places.
