Welcome to 646 Science Street, a striking modern 3-bedroom, 4-bath residence meticulously designed by Cipriani Studios, ideally located in the heart of Mt. Washington. From the moment you enter through the dramatic pivot entry door, the home makes an immediate impression with clean architectural lines, sophisticated finishes, oversized windows, and an abundance of natural light. The first floor features a stunning open-concept layout, highlighted by the gourmet kitchen, great room, and dining area, creating a seamless space ideal for entertaining and everyday living. This level also includes a powder room, access to a large rear deck constructed of low-maintenance materials, and a front-facing balcony, offering multiple outdoor spaces to relax and entertain. Designed for effortless smart living, the home is equipped with Control4 automation, 18 Paradigm in-ceiling speakers, motorized blinds, Ecobee thermostats, and a Vector security system. Fry Reglet trim is thoughtfully utilized throughout to create the illusion of floating floors and showcase the home’s refined modern aesthetic. The chef’s kitchen is a true centerpiece, featuring Calacatta quartz countertops with a waterfall edge, abundant cabinetry, a 42" Sub-Zero French-door refrigerator, 48" Wolf gas range with griddle and pot filler, Wolf wall oven and microwave, and a Miele stainless dishwasher. An adjacent wet bar accented with bold Broadway Black Velvet quartz includes a Marvel professional beverage center and a dual-zoned under-counter wine unit, adding both function and dramatic style. Upstairs, the spacious primary suite is a private retreat featuring floor-to-ceiling windows, a dramatic 18’ x 12’ tiled accent wall, and access to a private balcony. The suite also includes a large walk-in closet with an in-suite washer and dryer. The spa-like primary bath, enhanced by backlit mirrors, offers a heated Kohler soaking tub with bubble massage and a fully customizable 7-spray Kohler digital shower system, controlled by an in-shower digital touchpad. Two additional bedrooms are located on this level, each offering generous closet space and striking feature walls. The hall bath is beautifully appointed with a dual vanity featuring vessel sinks and a single, backlit mirror, providing both style and functionality. The entrance level enhances everyday convenience and flexibility, offering a full bath, an additional laundry area, ample storage, and direct access to the patio. A striking floating staircase with iron cable railings and LED-backlit treads provides architectural continuity throughout the home. Additional highlights include a two-car garage with EV outlet, a Generac generator, and an extraordinary rooftop terrace prepped with water and gas and featuring an integrated Weber gas grill. From this elevated outdoor retreat, enjoy breathtaking panoramic views of the city of Pittsburgh and the surrounding landscape, unforgettable sunsets, and front-row views of the city’s iconic firework displays. A rare opportunity to own a residence that seamlessly blends cutting-edge design, luxury finishes, smart technology, and exceptional indoor-outdoor living.
