Diamond Realty sells office and retail piece of Williamsburg’s Dime for $29M

Detailed view of the historic Williamsburgh Savings Bank in Brooklyn, New York, captured at sunset.

Diamond Realty has sold the office and retail component of the Dime, a 2020-built residential development in Williamsburg, Brooklyn, for $29 million, according to Commercial Observer. The sale includes the entire landmarked Dime Savings Bank of Williamsburg building at 209 Havemeyer Street, which has sat vacant for years despite its location in one of Brooklyn’s busiest retail corridors. The buyers are a group of local investors operating under two newly formed entities, Dime Commercial Holdings and Dime Retail Holdings. The transaction separates the commercial portion of the Dime project from its residential tower, which Diamond Realty developed as one of the more closely watched conversions in North Brooklyn.

The deal: buyers, entities, and price breakdown

Dime Commercial Holdings and Dime Retail Holdings step in

The buyer side runs through two entities: Dime Commercial Holdings and Dime Retail Holdings. Commercial Observer describes the purchasers as a group of local buyers but doesn’t name individual principals or a parent company behind the two entities. Structuring the purchase as separate commercial and retail holding companies suggests the new ownership may manage or eventually sell the office and retail pieces independently, a common approach when a single asset carries distinct leasing profiles under one roof.

How the $29 million splits across the landmarked bank and adjoining retail

The $29 million purchase price covers both the landmarked bank building and the retail and office square footage tied to it. Commercial Observer’s report doesn’t break out a per-component valuation, so it’s unclear how much of the total price reflects the vacant bank hall itself versus the surrounding retail and office space. What is clear is that the deal bundles the entire non-residential portion of the Dime into a single transaction, ending Diamond Realty’s ownership of that piece.

A long-vacant bank building changes hands

The Dime Savings Bank of Williamsburg building at 209 Havemeyer Street anchors the deal. The structure carries landmark status and has sat vacant for years, according to Commercial Observer, despite sitting at the center of a neighborhood that has seen steady retail and residential demand since the broader Dime development opened in 2020.

What’s included beyond the bank building

Beyond the bank hall itself, the sale includes additional office and retail space alongside or within the same commercial footprint. Commercial Observer’s summary doesn’t specify exact square footage for either the office or retail components, so the full scope of leasable space beyond the landmarked building isn’t detailed in available reporting.

How the office-retail piece fit into the larger Dime project

The Dime opened in 2020 as a residential development in Williamsburg, built around and incorporating the historic bank building. The project paired new residential units with the preserved landmark structure, a format that has become increasingly common in New York as developers work to satisfy landmarks preservation requirements while still adding new housing on a site. The office and retail component sold in this transaction is the commercial half of that original mixed-use plan.

Why Diamond Realty separated commercial from residential ownership

Commercial Observer’s report doesn’t state Diamond Realty’s specific reasoning for splitting off the commercial piece from the residential tower. Selling a commercial condominium or unit separately from an apartment building is a structure New York developers use routinely, particularly when the retail and office components have a different leasing timeline, financing structure, or exit strategy than the residential units above or beside them. That appears to be the case here, with the residential portion remaining under separate ownership while the commercial piece changes hands.

Who’s behind the purchase

What’s known about the local buyer group

Commercial Observer identifies the purchasers only as a group of local buyers operating through Dime Commercial Holdings and Dime Retail Holdings. No individual names, investment firms, or prior transaction history for this buyer group appear in the available reporting. The “local” label suggests ties to the Williamsburg or broader Brooklyn market, though the report doesn’t elaborate on their background or other holdings.

Diamond Realty’s remaining stake in the broader Dime development

The report focuses on the sale of the office and retail component and doesn’t specify whether Diamond Realty retains any ownership stake in the residential tower or other parts of the Dime development after this transaction. What’s clear is that the deal ends Diamond Realty’s ownership of the commercial piece tied to 209 Havemeyer Street and its associated retail and office space.

What happens next for the vacant bank space

Redevelopment or leasing plans, if disclosed

Commercial Observer’s report doesn’t detail specific redevelopment or leasing plans for the vacant bank building under its new ownership. A vacant landmarked structure at a high-visibility Williamsburg intersection may have drawn interest from retailers, restaurant operators, or event-space users over the years, but no confirmed tenant, leasing timeline, or renovation plan appears in available reporting.

Landmark status and its constraints on future use

The building’s landmark designation will shape whatever comes next. Any future exterior alterations, and potentially interior changes depending on the scope of the designation, would likely require review by the New York City Landmarks Preservation Commission before work could proceed. That review process tends to slow redevelopment timelines for landmarked commercial buildings, and it remains a factor for whoever eventually occupies or repositions the space.

Why this sale matters for Williamsburg’s commercial real estate market

A $29 million trade for a long-vacant landmarked bank building points to continued investor interest in Williamsburg commercial real estate, even for an asset that generated no rental income for years. The neighborhood’s retail corridor along Bedford Avenue and its side streets has drawn steady national retailer and restaurant interest since the pandemic, and a building with the scale and street presence of the Dime Savings Bank of Williamsburg is a rare chance to reposition a landmark asset in a high-traffic location. Whether Dime Commercial Holdings and Dime Retail Holdings move quickly to lease the space or hold it longer term is the next thing worth watching for anyone tracking North Brooklyn’s commercial market.
