A rectangular one-room apartment can stymie even the most creative interior design enthusiast, but add an alcove to that one room and the design options multiply considerably, which is what initially attracted us to this Prospect Heights co-op studio.

The top-floor apartment features a main room spacious enough to allow for two distinct living areas: a sitting room and a bedroom (you can add a bookcase/room divider for even more separation of space).

The alcove portion of the space pulls double duty as an entry foyer and dining room. Just off the foyer are not one, not two, but four closets, including a walk-in that can be used as a dressing room, an office, or just for straight storage. A windowed bathroom with both a bathtub and a shower stall and a small but functional windowed kitchen with cabinets that reach to the ceiling complete the space.

Located opposite Grand Army Plaza (a hop, skip and jump away from Prospect Park and the weekend Greenmarket, not to mention the Brooklyn Library, Museum and Botanical Gardens), this pet-friendly co-op is in a prewar building with a doorman, live-in super, porter, bike room, laundry and private storage. And it's about a third of a mile from four subway lines.

Priced at $349,000 with a maintenance of $616 a month, the 550-square-foot apartment is significantly more expensive than other studio co-ops in Prospect Heights, which, according to StreetEasy, sold for an average of $259,000 in the last 90 days. The additional space provided by the alcove and walk-in closet as well as the full-service building might account for the differential.
