Description

I looked at how the biggest NYC penthouse listings are positioned: they sell scale, privacy, "estate in the sky" feeling, 360-degree views, customization, ceiling height, and lifestyle amenities, not just bedrooms and bathrooms. Similar luxury listings emphasize full-floor privacy, private landings, dramatic views, large-format square footage, and rare multi-level layouts. (Paramount Realty USA1)

Here's the stronger version:

Sky Manor at Cassa Residences

The Crown Jewel Above Midtown Manhattan

Unprecedented scale. Unmatched privacy. Unlimited vision.

Sky Manor is a once-in-a-generation penthouse opportunity perched atop Cassa Residences at 70 West 45th Street in the heart of Midtown Manhattan. Spanning approximately 3.5 floors and over 8,200 square feet, this palatial residence offers the rare chance to create a fully customized private manor in the sky, built to the buyer's exact specifications.

Set high above the city, Sky Manor captures breathtaking 360-degree views of the Manhattan skyline, with exposures that frame the city from every angle. From sunrise over the East River to the glow of Midtown at dusk, the residence becomes a living canvas, with New York City as the backdrop.

This is not simply a penthouse. This is a private vertical estate above Manhattan.

With soaring ceilings reaching over 20 feet, dramatic volume, and extraordinary depth, Sky Manor gives a buyer the ability to design a residence at a level rarely possible in Midtown. The home can be delivered fully built out to your vision, allowing for a completely bespoke layout, finish package, and lifestyle program.

Create a full-floor primary retreat. Design a private cinema. Add a wellness floor with gym, sauna, massage room, yoga studio, and recovery space. Build a golf simulator, wine room, cigar lounge, private office, art gallery, children's wing, staff quarters, entertaining salon, or full wet bar. The scale allows the residence to function like a townhouse, mansion, and penthouse all in one, with the privacy and altitude only a true sky residence can offer.

Sky Manor is designed for the buyer who wants more than luxury. It is for the buyer who wants control, rarity, and presence.

The residence offers the flexibility to be used as an ultra-private personal home, a trophy pied-à-terre, or a high-end income-producing asset. Cassa Residences allows flexible 1 to 12-month leasing, and large-format short-term luxury inventory in Midtown is extremely limited. For executive stays, corporate housing, relocation clients, entertainment industry demand, family travel, and high-net-worth tenants seeking space and privacy, Sky Manor sits in a category of its own.

There are very few residences in Midtown that can offer this amount of square footage, this level of customization, this height, this view profile, and this leasing flexibility in one asset.

Cassa Residences brings a full-service lifestyle directly to the home. Residents enjoy 24-hour doorman and concierge service, hotel-style conveniences, fitness center, business services, housekeeping options, express dry cleaning, additional storages, fresh flower delivery, and access to the highly acclaimed Butter Restaurant within the building.

Located between Fifth and Sixth Avenues, Sky Manor places you in the center of Manhattan's most powerful corridor. Bryant Park, Rockefeller Center, Fifth Avenue shopping, Times Square, Grand Central, world-class restaurants, luxury hotels, corporate headquarters, and cultural landmarks are all moments away.

Sky Manor is the rare opportunity to create something that does not already exist: a private Midtown estate in the sky, built around your lifestyle, your vision, and your standard.

Midtown Manhattan is the city's primary commercial and transit hub, home to Grand Central Terminal, Rockefeller Center, Bryant Park, and the Empire State Building. The residential market features luxury condo towers, classic pre-war cooperatives, and postwar doorman buildings served by nearly every subway line in the system. Properties range from high-floor units with skyline panoramas to well-maintained co-ops along the tree-lined side streets east and west of Fifth Avenue.
