20 Mass earns GADA award

The Global Architecture Design Awards have honored the LEO A DALY-designed 20 Mass with a silver award for mixed-use development

The former federal office building at 20 Massachusetts Ave. in Washington D.C. was reimagined and rebuilt, becoming a 427,000-SF mixed-use development with office space, a luxury hotel — the Royal Sonesta Capitol Hill at 20 Mass — amenities and retail. The adaptive reuse re-stitched the existing building into an evolving urban context and created a vital new social and cultural hub for the neighborhood.

“This is another accolade to highlight the innovative design and placemaking at 20 Mass,” said Shanshan Yin, LEO A DALY senior project designer. “This project will improve the fabric of a key D.C. neighborhood for decades to come.”  

20 Mass has won several prestigious awards, including an American Architecture Award and a Rethinking the Future award. 

“I’m so pleased that 20 Mass continues to receive recognition for the hard work and dedication that went into the design,” said Andrew Graham, LEO A DALY technical director. “Our team worked closely to overcome many project challenges including existing conditions, schedule and the pandemic — to name a few.” 

Irena Savakova, Rauzia Ally, and Janki Bhatia also led the project team.
