About the Project

Site Plan #105

The next phase of Amazon’s HQ2 is a proposed redevelopment of the PenPlace block in Pentagon City. The applicants, Acorn LLC and JBG Smith, acting as Amazon’s development consultant, submitted a proposed site plan application on February 2, 2021.

The proposal includes approximately 3.3 million square feet divided across four buildings.

  • Three 22-story office buildings with ground floor retail
  • One destination- and amenity-focused building called “The Helix,” a unique biophilic double helix structure with plantings native to the Mid-Atlantic region.

In addition, the proposal includes a 2.5-acre public open space , detached retail pavilions, and underground vehicular access. Specific details of the open space will be evaluated through a Park Master Plan process.

Buildings will be designed for LEED Platinum certification and tailored towards achieving the County’s Community Energy Plan goals. In addition, the project would contribute to the County’s utility fund, public art, and streetscape improvements.

The proposed development would supersede the approved plan for Pen Place adopted by the County Board in 2013.

The application will require:

  • Pentagon City Phased Development Site Plan (PDSP) Amendment
  • Revised Pen Place Design Guidelines
  • Site Plan Amendment to incorporate the Residence Inn by Marriott property
  • New Site Plan for proposed development of Pen Place (capturing all phases)
  • Park Master Plan (PMP) for the design of the public open spaces on the site
