Out to Beverly Hills we go, where McMansions reign supreme and subways under high schools cause natural disasters..  A trio of low-rise apartment buildings at 332-336 Oakhurst Drive are slated to be demolished to make way for 31 residences.  The Oakhurst Condominiums, designed by Sherman Oaks-based Michael Ball Architects, would rise five stories above a subterranean parking garage.  Residential amenities include a lounge and fitness center on the project's ground level, with vehicular access provided by the alley at the back of the property.  The project's location, bisected by the border between Los Angeles and Beverly Hills, makes for an extra-cumbersome approvals process.  Other developments in the area include Genton Property Group's Wetherly Luxury Residences, which would create 55 condominiums within a 12-story structure.  That project saw construction fencing go up over the summer, despite opposition from the nearby Four Seasons Hotel.
