Terra Developers' $28M Purchase of 500 Columbus Avenue
Brooklyn-based Terra Developers has completed a $28 million purchase of 500 Columbus Avenue, a five-story mixed-use building on Manhattan's Upper West Side, according to property records filed at the end of last week. The seller was CKMR Corporation, the company formerly known as Sloan's Supermarkets and a longtime owner of the property.
The 35,300-square-foot building occupies the northwest corner of West 84th Street and Columbus Avenue, one block west of Central Park. Its ground-floor retail is anchored by a Gristedes supermarket, while the dozen apartments above have sat vacant for roughly 30 years. Bob Knakal of BKREA, the exclusive listing agent, said the residential portion is well positioned for conversion into condominiums.
The listing also flags room to build higher: BKREA says the 10,217-square-foot corner lot can support a vertical expansion. Yevgeniy Lvovskiy, CEO of ZHL Group, confirmed the purchase on behalf of Terra but declined to disclose the developer's plans for the site. ZHL previously represented Terra and other investment partners on a $27.6 million redevelopment site purchase in Long Island City, Queens, in 2024.
For the Upper West Side, the sale is a reminder that land one block from Central Park still commands a premium even when the building above it has been only partly used. The deal hands Terra a rare combination: an income-producing grocery store below and a dormant residential block above — a package that, judging by three decades of single ownership, does not come to market often.
What Terra's Upper West Side Play Means for the Building and the Block
The transaction looks simple on paper — $28 million, a grocery store below, a dozen empty apartments above — but the details of the building's history shape what Terra is actually buying.
Thirty Years of Vacancy, and What It Implies
Twelve apartments sitting empty for three decades is the most telling detail in the deal. It suggests 500 Columbus Avenue was held primarily for its ground-floor retail cash flow, and that the residential floors were effectively dormant — likely with dated systems and finishes that will need substantial work before any condominium units can be sold. That makes the recorded $28 million only the starting point of Terra's total investment; renovation and conversion costs remain undisclosed.
Knakal's framing of the apartments as well positioned for condo conversion is a broker's verdict, but the location supports it: a corner site one block from Central Park with an active grocery tenant and a dense residential neighborhood around it. The open question is cost, not demand.
Why Terra, and Why Now
Terra is a Brooklyn-based developer, and this purchase takes it deeper into Manhattan. The ZHL connection is the clearest strategic signal: Lvovskiy confirmed the deal, and ZHL represented Terra and other partners on the $27.6 million Long Island City redevelopment site bought in 2024. That repeat relationship points to a consistent playbook — acquiring underutilized properties and converting them to residential use — even though Terra has not confirmed its intentions for 500 Columbus Avenue.
The Gristedes Anchor Changes the Math
The supermarket tenant matters commercially. An operating Gristedes gives Terra income from the moment of closing, offsetting carrying costs while any residential work is planned and permitted. It also means the developer is buying a revenue stream, not just a parcel. For shoppers, the ownership change does not alter the store's day-to-day operation, though any construction above an active grocery store would require careful phasing.
The Vertical Expansion Question
The listing's claim that the corner lot can support additional floors is the deal's biggest contingency. Any vertical expansion would require New York City zoning and permitting approvals, a process that typically runs well over a year. If Terra pursues it, the project's value could rise well beyond a straightforward condominium conversion; if not, the economics rest on renovating the existing 12 units alone.
What the Seller Walked Away From
CKMR Corporation, the former Sloan's Supermarkets, held this property for decades. Its exit monetizes a legacy asset whose residential value was effectively frozen for 30 years. Whatever Terra pays to renovate, CKMR is converting dormant book value into cash at a time when Manhattan residential land remains expensive.
Reading the 500 Columbus Avenue Deal: Price Per Square Foot and Next Steps
The deal is a useful data point for three groups: developers pricing Upper West Side conversion projects, investors tracking Terra's strategy, and residents of the neighborhood.
- For developers benchmarking similar deals: the recorded $28 million price equals roughly $793 per square foot across the building's 35,300 square feet. That figure blends high-value retail with 30-year-vacant apartments, so it is a starting reference rather than a clean comparable — but it is the most concrete read available on what the market currently pays for mixed-use conversion stock on the Upper West Side.
- For investors following Terra: the 2024 Long Island City purchase with ZHL came in at $27.6 million; this deal is $28 million for a Manhattan corner site with an income-producing anchor. The similar price point, the same advisory partner and the residential redevelopment intent all suggest conversion is the base case here — and the absence of disclosed plans should be read as timing, not strategy uncertainty.
- For Gristedes shoppers: the ownership change does not affect the store's operation in the near term; the supermarket remains the building's anchor tenant. The main variable is the listing's stated potential for vertical expansion, which, if pursued, would bring years of construction over and alongside an operating store.
- For Upper West Side residents: new condominium supply on Columbus Avenue, if it materializes, would be a rare addition to a neighborhood with few conversion opportunities. Terra has not filed city plans or disclosed a schedule; that filing, when it comes, will define the scale and timeline of any conversion or expansion.
Risk & Opportunity Assessment
| Commercial Risk | Medium | Terra paid $28 million for a building whose 12 apartments have been vacant for 30 years; total project cost depends on undisclosed renovation scope, the physical condition of the units, and financing conditions, and the developer has not stated its plans. |
| Competitive Risk | Low | No named competitors or rival bidders are disclosed for the single-property acquisition; the Upper West Side condo market is active, but this deal does not shift market share among named players. |
| Regulatory Risk | Medium | The listing advertises vertical expansion, which would require New York City zoning and building-permit approvals; a condominium conversion would also trigger the city's condominium declaration and filing process. |
| Reputation Risk | Low | The sale has drawn no public controversy, though construction above an operating Gristedes in a dense residential neighborhood could attract community scrutiny during any redevelopment. |
| Technology Disruption | Low | No technology-driven business model or disruption is at stake in a traditional residential conversion project. |
| Commercial Opportunity | Medium | A corner lot one block from Central Park with an income-producing grocery anchor and explicit vertical expansion potential offers multiple value-creation paths, assuming renovation costs stay within market norms. |
