Sometimes it’s the little things in big cities that are the most striking. While the PH Towers Westgate, at 52 stories, isn’t exactly small, it is set back a ways from the clutter of the east side of Las Vegas Boulevard, amid other secondary Strip architecture. On that level, and despite the fact that we’re way “over” condo high-rises and reflective-glass structures at this point, it is a handsome building. But what we like most about Michal Postranecky’s work are the subtle design elements that emerge as you move around the tower. Our favorite vantage point: from the Cosmopolitan, where, out of nowhere, the building’s razor-sharp edge catches your eye as it cuts through the skyline. It’s a graceful, unexpected move on an urban fabric that needs a few more layers of surprises.
