Nestled between Park and Madison Avenues, just a short distance to Central Park, this beautifully reinvented 6,400 SF+/- historic townhouse features 6 bedrooms and 8 bathrooms across 6 levels, plus 1,165 SF+/- of exterior space including a rooftop terrace. The striking Neo-Grec brownstone façade is pristinely preserved, preceding an interior brimming with new custom, contemporary features. Originally built in 1883, this prewar townhouse was completely renovated and redesigned to the finest modern standards in 2015 by Peter Pelsinski of SPAN Architecture. This 19th century, one-of-a-kind townhouse was completely reimagined and renovated to the highest of standards. Each level was thoughtfully designed to optimize natural light throughout the living spaces while also providing seamless indoor/outdoor living with four outdoor terrace spaces from the garden level to the rooftop. The interiors take quality and luxury to a whole new level, featuring custom plaster ceilings, white oak hardwood floors, radiant heat flooring, steel windows and doors, and state-of-the-art security and smart home automation all controlled via touchpads. Up the front radiant-heated entry stairs, the main parlor floor awaits. Beyond the light-filled entry foyer unfolds an exceptional living experience enhanced by magnificent architectural millwork, two wood-burning fireplaces and other refined details. The parlor floor provides a grand entrance featuring floor-to-ceiling rift-cut oak wall paneling, a custom plaster ceiling and an elegant white oak and statuary bronze staircase accessing the garden level below, and master level above. Situated on the first floor is a formal living room with fireplace and rift-cut oak wall paneling. The dining room features cove lighting, an oversized skylight, glass wall overlooking the garden and well-appointed custom concealer butler’s kitchen. A wet bar and white marble powder room complete the parlor floor. The garden level provides convenient indoor/outdoor living and entertaining. A floor-to-ceiling steel and glass window wall opens to the rear L-shaped dining/lounging terrace with Ipe wood walls and custom built-in planters. A living room, chefs kitchen, guest quarters and powder room complete the garden level. The expansive garden level covered with limestone porcelain tile floors presents an open-plan kitchen and living room layout with a fireplace encased in a Bianco Namibia marble mantel. The top-of-the-line chef's kitchen is styled with custom rift cut oak veneer and glass and chrome cabinets, Bianco Namibia marble counters, chrome and black painted glass backsplash, and a premium Miele and Sub-Zero appliance suite. The second level is reserved for an all-inclusive master suite featuring a fireplace, dressing room, walk-through closet, study and a phenomenal private terrace. The master bath likens a spa with roman travertine stone slab flooring, a white oak vanity with stone countertop and oversized glass Hansgrohe rain shower. Floor-to-ceiling steel window and doors fill the second floor master suite with natural light and give way to a terrace featuring Ipe wood decking and a glass railing for a private indoor/outdoor sanctuary.
