This parlor-level duplex co-op housed in a magnificent townhouse on Pierrepont Street offers the grand proportions that come with brownstone living. Among its 2,600 square feet are three bedrooms, two bathrooms and a 15-by-36-foot living and dining area with stately pillars. Other authentic details include woodburning marble fireplaces, antique wood-paneled wardrobes and high ceilings throughout. And that’s just inside — there’s also an exquisite 2,000-square-foot, landscaped garden out back, which you can look out on from the graceful bay window of the upstairs master suite.
