    1901 L St. NW

Located prominently at the corner of 19th and L Street, 1901 L Street NW is an existing 8-story office building being vertically expanded four levels to a new, 12-story trophy class building. The building will contain a 3,000 SF lobby that extends to the corner of 19th and L Street, a 4,000 SF basement level fitness center, and a 3,000 SF penthouse amenity space with 2,700 SF of exterior roof deck.

During this tour project architect Devin Wilkins, structural engineer Mike Goss, and sr. project manager Michael Thiele will discuss the repositioning process and coordination efforts required to blend an existing building into new. The team will discuss the vertical building expansion, horizontal expansion, and unique and challenging design elements - including the tying together an existing building structure, new building structure, and custom, mullionless curtain wall system.

The session will address the materials being used throughout the building, the design interventions made to activate the building’s relation to the street, and systems implemented to enhance the experience of the everyday user.

Please Note: This tour takes place on an active construction site. Personal Protective Equipment including hardhats, safety glasses, a high visibility vest, and closed-toed shoes will be required for the tour portion of the event

Networking happy hour to follow the tour.
