In a desirable location of the South End’s Golden Triangle, this sleek modern upper triplex features an award-winning rooftop garden retreat and overlooks picturesque leafy streetscapes from both sides, illumined by bay windows on each level. The bright open floor-plan creates an airy loft-like ambiance set off by lustrous radiant-heated limestone floors and a striking glass-framed staircase. Through the elegant private entry, the parlor level flows as a versatile gallery-inspired living space. The next level’s casual living/dining areas open off the kitchen with Gaggenau and Bulthaup appliances. Encompassing the top level, the skylit primary suite is spacious and serene, with a Japanese-style soaking tub and shower in its bath area. An outdoor lounge space with a dining pergola, gas grill and sink, the beautifully landscaped roof deck captures skyline vistas from Back Bay to Downtown. The home has low VOC materials, whole-house water filtration, Lutron lighting and built-in speakers.
