Two developers have purchased a Chevy Chase hotel and adjacent retail store with a plan to revitalize the entire block. The developers Carr Cos. and The Donohoe Cos. Inc. announced they had jointly paid $74 million to buy the 44,688 square feet of retail space at 5520 Wisconsin Ave., and the 226-room Courtyard by Marriott Bethesda Chevy Chase Maryland hotel at 5500 Wisconsin Ave. Carr Cos. and The Donohoe Cos. plans to renovate the site with a focus on community-serving offerings, including hotel, retail and residences. Donohoe Hospitality Services will manage the hotel, which will continue normal operations by the development plan. Also Carr and Donohoe plan a residential project that will provide a complementary mix of uses with the adjacent hotel. Construction is expected to begin in late 2022.
