In this “stunning, all-new” loft-like corner co-op, the floors and the walls are really the stars of the show. “Beautiful,” shiny white porcelain floors stretch throughout the common areas, and there’s a built-in “media wall” in the double living room. At the same time, by turning nine rooms into seven large spaces, the renovators knew when to forgo walls altogether. The approximately 2,500-square-foot spread includes three bedrooms and 2½ bathrooms — with a master suite that features separate his-and-hers dressing areas — along with a “big, open” dining room and new, windowed eat-in chef’s kitchen. The best features have no walls at all: There are setback mahogany-decked terraces on three sides. Agent: Margaret Anna, Halstead Property, 212-381-3384
