Architectural elegance meets contemporary cool in this spectacular multi-level penthouse unit in the historic Whitehall building at the Waterworks. Double-height ceilings, exquisite geometric windows, multiple skylights, and a stone-clad floating fireplace give this unit modern charisma, while beautiful hardwood floors and curated fixtures and finishes deftly balance the building's Beaux Arts grandeur. The kitchen, anchored by a granite-capped island & Bosch & Subzero appliances, opens up to the living area and is perfectly suited to entertaining. Two upstairs bedrooms, both ensuite with sleek marble baths, enjoy terraces and custom closets. A smart office landing and in-unit laundry add to the convenience. A sculptural staircase leads to an additional 1300+ sq ft private roof deck with city & reservoir views. Enjoy the ease of Chestnut Hill's most coveted elevator complex, with on-site management; concierge; two parking spaces (one is garage); gym; and easy access to shops & the T.
