Only three owners have occupied this classic c.1899 triple-bay, four-story brownstone on Park Slope's coveted Third Street. The current owners have honored much of its 19th c. detail --pocket doors, wainscoting, cabinetry, stained-glass panels and skylights --and meticulously restored and renovated it to exacting 21st-c. standards. Enter the home either up its sweeping stoop or at garden level. The first floor hosts an extra-wide entry hall; and an elegant front-facing dining room with built-in cabinetry and carved wood mantel, withWilliam Yeoward Englishwallcovering as adornment. Host a large dinner party or holiday meal: neither is too large for this room to graciously accommodate. The garden-facing eat-in chef's kitchen is a bespoke Eggersmann design. An oversized waterfall island is clad in book-matched granite and has a set-in copper bar sink, floor to ceiling cabinetry and a cast-concrete floor. Appliances are top tier: a 48-in. SubZero fridge; six-burner Wolf stove; Bosch electric oven, microwave, and warming drawer; and a Miele dishwasher. The ledgestone backsplash leads outside through a wall of glass creating a beautifully integrated design. The landscaped garden, accessed through French doors, is serene and replete with gas grill and planting beds. The laundry/mud room is spacious: folding, ironing, hand washing and prep for gardening can all take place here. The powder room features Art Nouveau tile in neutral tones and is privately tucked away here. The parlor floor, with soaring 12-ft. ceilings, features a formal front living room, middle parlor or den, and back office. The grand living room is illuminated by a bay of south-facing windows and ornamented with elegant hand-painted Gracie wallcoverings and an oversized mantel. The den, a handsome companion to the living room, is papered in horsehair and features a wet bar, illuminated leaded-glass cabinetry and a gas fireplace. The cozy private office overlooks the garden and has plenty of space for desk, bookshelves and storage. The third floor is host to the primary bedroom, paneled in Jim Thomspon silk with matching drapery and lit by a triple bay plus a fourth window. The decorative fireplace has a gilded overmantel. The expansive primary bath has been fashioned with a double marble vanity, step-in shower, Roman bath and private toilet. One entire wall is dedicated to three wide closets concealed by sliding panels. The rear-facing bedroom could also function beautifully as a study, boasts a working gas fireplace, and leads to a 150 sf deck, which overlooks the garden. The fourth floor is host to yet another enormous front-facing bedroom with an en suite bath featuring a green resin vanity, tub and shower, sklylight, exposed brick and built-in storage. The rear bedroom has another wood mantel with a cast-iron fireback, a wall of closets and a bathroom accessed either privately or from the hall. An intricate stained-glass skylight and linen closet are located at the landing. From its restored original detail, which proves 19th century craftsmanship is enduring, to its sophisticated upgrades and fine decoration, 545 Third Street is the perfect example of why Park Slope is a renowned destination neighborhood.
