In the New York City market, there is not much open land left to build on. So some developers are building up instead of out. The Bowen, just completed at 289 Schermerhorn Street in Downtown Brooklyn, kept a 100-year-old office building and added new floors on top, turning it into 71 condos. For buyers and sellers in New York Real Estate, it is a clear example of how older buildings can become new homes, and it is a trend you can also see across the Manhattan Housing Market in Chelsea, the West Village, Gramercy, Tribeca, SoHo, Hell's Kitchen, and the Upper West Side.
What Is a Vertical Expansion?
A vertical expansion adds new floors on top of an existing building. Instead of tearing a building down, the developer keeps the original structure and builds above it.
At The Bowen, the original brick base stays in place, and a dark metal addition with large floor-to-ceiling, industrial-style windows rises above it. The contrast between old and new is part of the building's look.
Why Developers Are Building Up
Limited land: Open lots are rare, especially in Manhattan.
Keeping character: The original facade keeps the building tied to its block.
Faster path to homes: Reusing a structure can be simpler than building from scratch.
More homes: Adding floors can double a building's size, as it did here.
What Buyers Should Know About Expanded Buildings
Old base or new addition: Ask which part of the building a home is in. Ceiling heights, windows, and views can differ.
Light and views: Homes on the new upper floors often get more light and better views.
Systems: Ask which systems are new, such as plumbing, heating, cooling, and windows.
Sound: Check how sound travels between floors, especially where old and new meet.
Monthly costs: Review the offering plan and building budget with your attorney.
Old Meets New Across the Manhattan Housing Market
Chelsea: Former industrial buildings with modern additions near the High Line.
West Village: Historic buildings with careful rooftop additions where rules allow.
Gramercy: Older buildings updated with new interiors near the park.
Tribeca: Warehouses converted into lofts, some with new penthouse floors.
SoHo: Cast-iron buildings with modern interiors behind historic facades.
Hell's Kitchen: Older walk-ups and commercial buildings becoming new homes.
Upper West Side: Prewar buildings with renovated interiors and the occasional new addition.
What This Means If You Are Selling in New York Real Estate
New conversions and expansions give buyers more choices. If you own in an older building, highlight what newer projects cannot easily copy, such as original details, established finances, and a proven building history. Price your home against recent sales of similar homes nearby.
My Perspective as a New York City Real Estate Agent
Ask which part of the building you are buying in. Homes in an original base and a new addition can feel very different.
Upper floors in an addition often win on light. New floors above older neighbors can offer brighter rooms and open views.
Compare before you commit. Look at conversions, expansions, and ground-up new buildings side by side to find the best value.
