President Trump has nominated Trevor Traina, the San Francisco tech entrepreneur whose restoration of a property on the Inverness Ridge stirred local controversy in recent years, to serve as ambassador to Austria. The Senate must approve the nomination to the post, which has been vacant since former Ambassador Alexa Wesner, an Obama appointee who also held a technology background, resigned last January. Yet plans for Moonrise Kingdom and its handful of 1960s structures that are considered significant examples of the green building movement have not changed. “We remain very committed to the Waite property and plan to restore [it] little by little,” Mr. Traina’s wife, Alexis, said. Though the Trainas bought the property in 2013, the Board of Supervisors did not approve their plans until last August, following two appeals from the Inverness Association, which argued the project was too large and was out of character with the neighborhood. The 5,500-square-foot project will restore three cabins built by the late Howard Waite, including two known as the Windmill and Howard’s House that Ms. Traina said were her family’s first priorities for restoration. The county’s approval of the development was contingent upon the Trainas halving the size of their home, altering the tall Windmill to better blend into the surroundings and dedicating one cabin for use by a caretaker. Mr. Traina co-founded five companies, including his latest venture, IfOnly.com; Microsoft purchased his first company, CompareNet, in 1999. Interestingly, his late grandfather, Wiley T. Buchanan Jr., served as U.S. ambassador to both Austria and Luxembourg.
