BOSTON – December 21, 2021 – Global law firm K&L Gates LLP will be relocating its Boston office in 2023 to One Congress, a one million square foot, trophy office development owned through a joint venture between Carr Properties and National Real Estate Advisors, LLC (National) on behalf of its clients. The HYM Investment Group is the lead developer of the project together with Carr Properties. K&L Gates will occupy two floors of the building beginning in mid-2023.

“One Congress Street, located in a completely revitalized and flourishing part of the Financial District, exemplifies the future of office space in Boston, with amenity offerings to our lawyers and staff that will make the ultimate return to work fresh and exciting, and in step with the modern way of doing business in an office setting,” stated Mark E. Haddad, managing partner of K&L Gates’ Boston office. “We are very excited about our prospective new office space and partnering with Oliver Carr and his team, who not only is involved with developing the project but will be overseeing day to day operations of the facility.“

“We are thrilled to welcome K&L Gates to One Congress as their future home in Boston.  One Congress is a tremendous project that will offer a market-leading experience for the K&L Gates team,” said Oliver Carr, CEO of Carr Properties.

“We have created a premium, cutting-edge office environment at One Congress, and we are proud to welcome K&L Gates to the project,” said Jeffrey Kanne, President and CEO of National Real Estate Advisors. “The industry-leading organizations making their way to One Congress speaks to the quality of the project and the location.”

John Barry, Peter McQuaid and Jeff Landers of CBRE represented One Congress in this transaction. Dave Fitzgerald and Tim Howe of CBRE represented K&L Gates.

Designed by world-renowned architects Pelli Clarke Pelli and CBT Architects and interior design firm Gachot Studio, One Congress is becoming a new fixture of the Boston skyline and provides those who occupy the new trophy office space with breathtaking panoramic views of the city, Boston Harbor, the Financial District and the Charles River. With cutting-edge building systems, technology and services, One Congress has been constructed with market-leading sustainable and health-conscious features. The building is designed to provide an elevated experience for its customers, with luxury amenities that include a market-leading fitness center and spa, high-quality onsite food and beverage outlets, collaborative environments, private spaces, and personalized services.

One Congress broke ground in June of 2019 and construction is expected to be completed at the end of 2022. K&L Gates will join anchor customer, State Street Corporation, the Boston-based, Fortune 500 financial services firm, in the one-million-square-foot office tower.

We have seen signs of tenant optimism and we are excited to welcome another distinguished company to One Congress,” said developer Thomas N.
