Gould Property Co. has launched a $25 million renovation of its 440,000-square-foot office building located at 401 Ninth St. NW. Rebranded as 401 on Ninth, the project aims to modernize the space as the firm seeks new high-end occupants.
Why it matters
The redevelopment addresses a limited supply of high-quality office space in Washington, positioning the building to better compete for top-tier legal and corporate tenants. Gould Property Co. is creating large contiguous floor plates to appeal to companies looking for expansive footprints in the city's East End.
The 440,000-square-foot property is undergoing a $25 million renovation. Once completed, the building will offer 175,000 square feet of contiguous top-of-building space.
The players
Gould Property Co.
This is a real estate development and management firm that operates multiple commercial properties in the Washington metropolitan area.
Troutman Pepper
This is a national law firm that is currently vacating 80,000 square feet of office space at the 401 Ninth St. NW location.
The details
The renovation project features a major lobby upgrade, the construction of a new fitness center, and a new indoor-outdoor penthouse amenity dubbed The Solarium. The developer is also upgrading a two-level conference center to enhance the site's appeal following the departure of law firm Troutman Pepper from the top two floors.
Timeline
Renovation work officially began at the property in September 2026.
Construction on the project is expected to reach completion by the fall of 2027.
Contiguous top-floor space will be ready for new tenants by the third quarter of 2029.
Roadmap
This project reflects the broader push by owners of legacy office assets to upgrade amenities to attract tenants amid a flight-to-quality market shift. By reconfiguring floor space, Gould Property Co. is attempting to mirror the appeal of newer inventory that currently commands higher premiums.
Nearby office workers and local businesses in the East End should expect construction activity at the site through the fall of 2027. Tenants currently seeking space will see new large-scale options becoming available in the coming years.
The takeaway
Property owners are increasingly relying on high-end lifestyle amenities like penthouses and fitness centers to retain value in the current office market. Business leaders should monitor these facility upgrades as potential benchmarks for future site selection requirements.
