A compromise on location and design is typically one of the hazards of searching for a large family-size apartment with private outdoor space. But this duplex at 422 East 72nd Street breaks that mold, offering four bedrooms spread over 2,900 square feet with a terrace on each level. The building, The Oxford Condominium, is in a serene corner of the Upper East Side, and the apartment was created from two units, connected by a staircase and completely renovated by architect Peter Wiederspahn. A contemporary combination without the headaches and hassles of doing the job yourself? Now that’s what we call a turn-key home. Every room is flooded with sunlight and offers expansive East River and city views, and for the price, $4.25 million, the amount of space is truly impressive. No compromises required.
