With a skillful eye for design, shrewd sourcing and a clever sense of space, the owners of this perfectly proportioned apartment have transformed it into a chic haven. Situated on the top floor of a regal Eighth Avenue mansion, this apartment has been   given a fresh, contemporary overhaul. The main space is its kitchen/living/dining room, flooded with light from southwest-facing windows with a secret coat closet tucked away. The kitchen, efficient in layout, has stainless-steel appliances, oak countertops,   a white subway tiled backsplash, open shelving and a pegboard to hang just about all of your utensils. The wood-burning fireplace is flanked by floor-to-ceiling bookcases and built-in secretary desk-for-two, making work-at-home not only possible, but a pleasure.   The bedroom has been fashioned with a custom wardrobe that spans one wall and encloses drawers and bars eliminating the need for dressers. The remodeled bathroom is super swanky with Heath tiles on the floor and walls, a glass paneled tub and shower, an oversized   cantilevered sink and a Toto Washlet. An electric Samsung washer and dryer hide behind rattan closet doors. The oak floors have been whitewashed, and the walls painted in subdued tones, with wainscoting, cornices and moldings added. Forbes & Lomax light switches,   and lighting by Tom Dixon and Lindsey Adelman add to the uniqueness of this renovation. The board maintains a very low underlying mortgage and a healthy reserve. As for its north Slope location, express trains, Prospect Park, the weekly farmer's market and   shopping are all within arm's reach.
