Great Bones: Mint-condition condos in intimate prewar buildings as London Clay Townhouse prepares for sales

In New York City, luxury living is often measured vertically, with sky-high towers, hotel-style services, and amenity suites large enough to feel like private clubs. But for a certain kind of buyer, the more compelling dream is smaller, quieter, and closer to the street: a mint-condition home in an intimate prewar building where privacy, character, and neighborhood connection matter more than a doorman or a 50,000-square-foot amenity package.
Intimate condominium conversions in small prewar buildings offer a rare middle ground between a townhouse and a traditional apartment. They provide the ease of condo ownership, modern/upgraded systems, and renovated interiors, but with the scale and discretion of a private home. With only a handful of neighbors, these buildings can feel calmer and more personal than larger developments, while still offering the lock-and-leave convenience that makes apartment living appealing.

Townhouse-style privacy paired with the ease of condominium living is the idea behind London Clay Townhouse, a boutique conversion at 32 East 22nd Street in Flatiron situated on a quiet, tree-lined block between Madison Square Park, Gramercy Park, and Union Square. The conversion sits moments away from the newly converted Flatiron Building and shares its street with the soaring, recently finished glass condo skyscrapers of One Madison and Madison Square Park Tower.

The building's repositioning was conceived by Buttonwood Development’s Andrew Heiberger and Wheelhouse Property’s Howard Lev, the rowhouse will be composed of three bespoke condo homes, a Garden Parlor with a private garden, an Upper Parlor with a private terrace, and a Penthouse Duplex with a private roof terrace and city views. Sales are to officially begin around the end of July / early August. Interested buyers can subscribe for updates via our building page or the development's registration website.

“Nestled on a quiet, tree-lined block between Madison Square Park, Gramercy Park, and Union Square, it offers a lifestyle that's both peaceful and deeply connected to the city's best dining, culture, and green space. Boutique townhouse condominiums of this caliber are incredibly scarce, making opportunities like London Clay Townhouse increasingly valuable for today's buyers.”

Their appeal often starts with the buildings themselves. Prewar construction tends to have strong structural bones, generous proportions, high ceilings, substantial walls, and architectural details that newer construction often tries to recreate. In the best conversions, developers preserve or reinterpret elements like original brick, moldings, staircases, fireplaces, tall windows, or formal room proportions, then pair them with modern kitchens, updated baths, central air, new mechanicals, and private outdoor space.
At London Clay Townhouse, interiors by Haley Lankau of Studious Dsgn, alongside Stocki Design, will blend historic character with contemporary finishes including soaring ceilings, custom millwork, natural stone, integrated Miele appliances, Lefroy Brooks fixtures, Toto smart toilets, and Farrow & Ball finishes. The result is meant to feel neither like a museum piece nor a generic new condo apartment.

“London Clay Townhouse represents an exceptionally rare opportunity, pairing the character, craftsmanship, and scale of a historic townhouse with one of the most coveted residential settings in downtown Manhattan,” said Andrew Heiberger, Founder and CEO of Buttonwood Development.

There are tradeoffs of living in this type of building of course. Small buildings often do not offer the doorman, elevator, gym, pool, screening room, or children’s playroom found in larger condos. But for buyers who value privacy, fewer shared spaces, lower-key living, and a stronger sense of place, that can be part of the attraction. These low-rise buildings are often woven directly into the residential fabric of their blocks, creating a more meaningful connection to their neighborhoods versus a conventional high-rise.
“What makes boutique townhouse condominiums so compelling is that they deliver a residential experience fundamentally different from a traditional apartment building,” said Howard Lev of Wheelhouse Property. “With just a handful of homes, residents enjoy exceptional privacy, quiet, and a true sense of ownership, while still benefiting from the ease of condominium living. At London Clay Townhouse, each residence also offers a private outdoor retreat. Combined with the building's preserved architecture, generous proportions, and timeless character, this creates a living experience that simply can't be replicated through new construction.”

Listings of this kind remain relatively rare, but they are becoming more common as ready-to-build development sites in sought-after neighborhoods have grown scarce. In some cases, developers are converting older rental or mixed-use buildings, sometimes controversially, into a few high-end condominium residences that combine the best of old and new. For buyers seeking a balance between suburban privacy and city convenience, these homes may just be the right fit: private entries or semi-private landings, outdoor space, flexible layouts, and an everyday connection with the surrounding neighborhood.
