Description

390 Union Street is a lovingly restored, renovated 3-family brownstone with an owners duplex and two floor-through rental apartments above. The deep setback for the front garden, characteristic of the neighborhood, enhances light to the interior. Natural light in the home is enjoyed all day and the staircase is lit from above by a large skylight. Picturesque views from every window include open sky, the 19th-Century brownstone block, historic Saint Agnes Church, a beautifully landscaped front garden and a rear garden as close to Provence as one might imagine. The parlor floor has 11' ceilings, a center kitchen with cherry cabinets, granite counters, Sub-Zero fridge, Thermador range, and Miele dishwasher. A Jack and Jill bath on the garden level is between two bedrooms, with laundry in hall, and there is a powder room on the parlor floor. French doors on both levels overlook and open to the rear garden with grape arbor and fruit trees and an awning over the patio for sunny days. Original details have been preserved throughout, including fireplace mantels, plaster moldings, ceiling medallions, hardwood floors, staircase and doors. Plumbing and electrical systems have been upgraded and replaced, a new boiler and hot water heater were installed in 2012 and the duplex has 2-zone CAC. The finished basement with 8' ceilings is currently used as a home gym, and has a separate storage/work room behind. With approximately 3000 sf of living space, not including the basement, there are 4 bedrooms, 3.5 baths, and 3 kitchens. Carroll Gardens is a popular Brooklyn brownstone destination with international appeal. Carroll Park, the year-round Sunday Green Market and numerous specialty food shops and restaurants line Smith and Court Streets. Trendy Gowanus, just across Hoyt, has galleries, more shops and restaurants and a Whole Foods Market on 3rd Street. The bike lane on Union is the direct route to Prospect Park. F/G subway is two blocks away. This turn-key property is a wonderful home with the added benefit of rental income and is delivered vacant and pristine.
