About this home

Perched on the top floor of the sought after Crystal House, this extensively renovated Junior 4 residence offers 950 square feet of thoughtfully designed living space filled with natural light. A dramatic wall of windows creates a bright, open atmosphere throughout while the flexible floor plan easily accommodates today’s lifestyle needs, whether for a dedicated home office, den, or guest space. Every aspect of the home has been carefully reimagined, including a custom kitchen featuring quartz countertops, new cabinetry with pull-out shelving, and brand-new appliances. The spa-inspired bathroom offers an oversized soaking tub, generous vanity storage, makeup lighting, and timeless tile finishes. Additional upgrades include dimmable lighting throughout, water purification systems serving both the kitchen and bath, and three new Friedrich in-wall air conditioning units. 7F's storage is exceptional, with a walk-in closet complemented by an approximately 17-foot wall of additional closets, providing a level of organization rarely found in one-bedroom apartments. Crystal House is a full-service cooperative offering two elevators, a friendly door staff, live-in superintendent, 7 laundry rooms, and immediately available indoor garage parking. Ideally situated near the vibrant downtown White Plains business district, residents enjoy convenient access to Metro-North, restaurants, shopping, parks, and major transportation corridors while benefiting from a location that feels distinctly residential.
