Contemporary penthouse

With sunset views from a full-width, top-level balcony high above Hyde Park, this penthouse goes full throttle. Espresso-toned floors, glossy black kitchen cabinets, slate-themed ensuites, and dark paneled walls take a muscular approach. Pour something strong in the formal dining room for 12, spread out on the home theater’s sectional, and watch for double-decker buses on Park Lane below.
