Silverstone Group moves toward another 16th Street conversion as boutique condo plans expand in Dupont Circle

A new chapter for a prominent 16th Street property

A Washington-based developer is advancing plans tied to the continuing reshaping of several rowhome-scale buildings along the 16th Street NW corridor, where former institutional and office uses are increasingly being repositioned for residential ownership. Silverstone Group, a District-focused investment and development firm founded in 2018, has been working on a boutique condominium conversion at 1710 16th Street NW and is now reported to be nearing an additional deal involving another historic rowhome on the same corridor.

The 1710 16th Street NW building, a four-story structure of roughly 6,500 square feet, previously served as the headquarters of the Association of American Geographers before the organization moved to 1701 Pennsylvania Avenue NW. The site sits across from the Scottish Rite’s House of the Temple, placing it within one of the city’s most closely scrutinized historic and design contexts.

What is planned at 1710 16th Street NW

Silverstone Group has outlined a seven-unit condominium project that would convert and expand the existing structure. Plans call for enlarging the building to about 8,500 square feet through a rear addition, with exterior design work by 2Plys Architecture, interiors led by the developer’s in-house design operation, and construction handled by its affiliated contracting arm.

• Planned scale: seven condominium units
• Existing size: about 6,500 square feet, with an expansion target of about 8,500 square feet
• Key approvals: Historic Preservation Review Board approval secured in May 2025

The property changed hands in October 2025 for $2.4 million. District assessments placed the property at $2.5 million for the same year. Public filings associated with the prior ownership indicate that a foreclosure notice was recorded in February 2025 stating that $1.8 million was owed on a $2.5 million loan before the sale.

How the deal fits a broader corridor pattern

The 16th Street NW spine, particularly around Dupont Circle, has long combined residential architecture with office and nonprofit occupancy. Recent transactions point to a shift toward smaller-scale, high-value residential redevelopments, including multiple rowhome-sized office buildings being repositioned as condominiums rather than remaining in institutional use.

Within that context, Silverstone Group is described as nearing another agreement involving a historic 16th Street rowhome slated for condominium conversion, signaling continued acquisition interest in buildings where entitlement pathways—especially historic review—can determine project feasibility and timing.

The ongoing conversions underscore how historic-building approvals, financing pressures, and shifting demand for office space are intersecting on one of Washington’s most prominent residential corridors.

What comes next

For the 1710 16th Street NW project, next milestones typically include final construction documents, permitting, and a sales timeline as unit layouts and pricing are finalized. For the additional deal under discussion, details such as address, unit count, and approval status have not been publicly confirmed.
