Description
Apartment 15C is one of the very special residences at 378. With a gracious private entrance and open views south, east and north, 15C is a wonderful aerie. The grand and gracious arrival gallery of 15C leads to a wonderfully proportioned Great Room with a kitchen (crafted by Christopher Peacock with Sub-Zero and Wolf appliances) which is open and contemporary but has a hidden pantry for a more formal moment and a great banquet possibility for cozy kitchen dinners. With two terraces providing private outdoor spaces, 15C can be a true five bedroom or a four bedroom with a library/guest bedroom. A primary bedroom suite with a bathroom that feels like a five star hotel and private outdoor space makes this one of the most unique apartments at 378 West End.
The residences at 378 West End Avenue are designed for the way people live today. Each of the fifty-eight residences, designed by COOKFOX and developed by Alchemy Properties, has gracious proportions and rich materiality. There is a wonderful interplay between the classic and contemporary. Top-of-the-line technology includes building water and air filtration systems, and elevators outfitted with state-of-the-art touchless technology.
With over 11,000 square feet of amenities including a 75 foot lap pool, a private garage & drop off, parking (for an additional fee), private garden, music recording studio and practice room, basketball court, squash court, fitness center, movie room, reading room and lounge with pool table, the space outside your apartment is as special as your private residence.
