20 Mass Earns Rethinking the Future Award, an International Honor

The Adaptive Reuse Project Won in the Mixed Use (Built) Category

20 Mass

An international jury has honored the LEO A DALY-designed 20 Mass project with a Rethinking the Future Award, which recognizes excellence in global architecture.

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. LEO A DALY designed the mixed-use structure for developer The RMR Group.

“The completion of the revitalization project at 20 Massachusetts Ave NW represents more than just a successful fusion of history and modernity; it symbolizes the collective effort and vision of stakeholders committed to creating a vibrant mixed-use destination that enriches the surrounding community and enhances the city’s urban fabric for generations to come,” says the award’s website.

Christopher Bilotto, executive vice president of The RMR Group, has said: “This successful conversion of a former government office building into a Class A mixed-use destination is the culmination of significant efforts by RMR, its client Office Properties Income Trust, and the redevelopment project team.”

20 Mass has previously been honored with several other awards, including ULI Washington, NAIOP’s DC/Maryland chapter and the Washington Business Journal. Royal Sonesta at 20 Mass is on the shortlist for the 2024 International Hotel & Property Awards. In addition to these accolades, the vibrancy of the public spaces, the mix of guests and local community at the street level restaurant, the completely booked conference spaces and Grand Ballroom for the next 3 years are a testament to a successfully implemented design vision.
