Non-cookie-cutter building with exceptional luxury detailing in common areas and units. This building is 3' wider than most 6 flats allowing unique floor plans. Enter up the full limestone stoop, through a hand-made 8' mahogany door into a marble foyer with wainscoting, crown molding and a hardwood common staircase.  This 4 bed, 3.5 bath with walk-in laundry room duplex down is differentiated through 40+ inch basement windows, 10' ceiling height, efficient / practical layout, finish quality and well-conceived livability features - plus the extra building width. Ceiling height and oversized lower-level windows successfully combat 'duplex down feel' of many competitors. Finishes also outpace all competition with Dornbracht plumbing fixtures throughout, Kalista Mick DeGuilo kitchen sink, numerous ceiling details, extra thick 8' tall stile and rail interior doors, Wolf and Sub-Zero appliances, impressive natural stone tilework, radiant heated floors, and the stamped concrete covered rear patio. Sound transfer is mitigated by a 9-layer floor system and all vertical walls have soundproofing. A/V includes all rooms pre-wired, building camera hookup, unit security system, and advanced building entry system compatible with Amazon's new access protocols to reduce package theft. Storage is abundant with a kitchen pantry, coat closet and storage closet on the main floor plus utility, linen and mud-room closets in the lower level. The laundry is walk-in. The front living/dining room is staged for dining but wired for TV/sound to be a 2nd living space. A cased opening and pocket door provide additional privacy to the kitchen as well. The ship lapped kitchen island is 10' with seating for 6 by having two sides overhang - allowing face-to-face seating at the counter. Each of the 4 bedrooms is larger than typical. The primary/master suite closet is a huge 10' x 6'; shower is large enough for multiple people with steam, regular, rain and hand features; private toilet closet; and an oversized vanity including towel drawers. Other bedrooms are large with built-out closets. The 4th bed and en-suite is near the rear door allowing options for in-law, nanny or guest use. The garage includes a 30" common area next to this unit's space which could be used for stroller or other storage. Builder is reputable and engaged with occupants to meet any customization needs.
