Description

Welcome to 270 Dean Street - This 20-foot-wide, two-family classic Boerum Hill brownstone was fully gut-renovated in 2013, seamlessly blending timeless townhouse architecture with modern luxury. The renovation included all-new plumbing, electric, and central air conditioning throughout, creating a truly turnkey home. Configured as a two-family home, the property offers a gracious owner’s triplex above a spacious garden rental. The owner’s triplex spans three sun-filled floors with four bedrooms and three and a half bathrooms. The main living level is ideal for both entertaining and everyday living, featuring a striking chef’s kitchen with Nobilia European designer cabinetry, marble countertops and backsplash, and premium appliances. The kitchen flows into generous dining and living areas, accented by two original marble-mantled fireplaces. From this level, step directly onto a large 21’ x 12’ private terrace overlooking and leading down to a landscaped perennial garden with irrigation—an exceptional extension of the living space. Upstairs, four large, bright bedrooms with custom closets (including custom walk-in closet in the primary) and three full bathrooms provide flexible living, with baths finished to high standards featuring Restoration Hardware vanities, Kohler Purist fixtures, and Kohler cast iron soaking tubs. A full laundry room is also located on this level. The garden level features an approximately 900-square-foot one-bedroom rental with a private entrance, designer kitchen, in-unit washer and dryer, and central air—ideal for income, guests, or flexible use. A cellar with separate entrance offers additional storage. Enjoy unobstructed views of the Brooklyn skyline from the stoop and a prime location within a ten-minute walk of Barclays Center, BAM, Whole Foods, Trader Joe’s, and an array of beloved cafés and restaurants. With easy access to the F, G, A, C, R, 2, 3, 4 and 5 trains, this home offers exceptional convenience and an elevated Brooklyn lifestyle.
