The RMR Group announced the completion of a redevelopment project at 20 Massachusetts Avenue NW ("20 Mass") in Washington, D.C. and recognition of the project for Best Renovation by NAIOP DC|MD. 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. NAIOP DC|MD recognized 20 Mass for Best Renovation at the association's recent annual Awards of Excellence Gala, which awards outstanding achievement in commercial real estate.

The reimagined 20 Mass includes 13,800 square feet of retail, the recently opened 274-key luxury Royal Sonesta Washington, D.C. Capitol Hill hotel, 183,000 square feet of premier upper level office space and a 14,500 square foot penthouse amenity space with views of the Capitol. Positioned at the intersection of Massachusetts Avenue and F Street NW in the prestigious Capitol Hill neighborhood, 20 Mass is adjacent to Union Station, a major regional transit hub. 20 Mass also offers direct access to upscale dining, world class museums and landmark buildings including the United States Capitol and Supreme Court of the United States.

The property is 54% leased to Sonesta International Hotels Corporation (Sonesta), which opened The Royal Sonesta Washington, D.'C.Capitol Hill hotel in September 2023. As the first luxury hotel to open in Capitol Hill in nearly 40 years, the hotel features 274 guest rooms that are some of the largest in the city, with an average room size of 480 square feet. KNEAD Hospitality + Design debuted its new 200 seat French restaurant Bistro Du Jour on the hotel's main level with a stylish bar and lounge and outdoor cafe serving breakfast, lunch, dinner, weekend brunch and happy hour.

As a LEED Gold and WELL certified property, 20 Mass was redesigned to integrate sustainable and tech forward components that benefit hotel guests and office tenants. A new glass curtain wall facade and 10-story atrium cut into the existing structure bring in natural light while a green roof features drought-resistant planting and an integrated stormwater management system. Wellness amenities in the building include an on-site fitness facility with Peloton bikes and adjoining yoga studio as well as water refill stations and EV charging stations in the garage.

The property also offers tenants multiple conference centers with private terraces, multipurpose meeting rooms and a tenant experience app providing a mobile concierge and touchless systems.
