Architectural studio Graham Baba and landscape design firm Greenworks have released images of their plans to regenerate Terminal 1 on the Vancouver waterfront in Washington state.

The building project coincides with a $1.5bn initiative by Waterfront Vancouver LLC and Gramor Development to reconnect 35 acres of the Columbia riverfront to downtown Vancouver. Both areas have been separated for over a century.

Port of Vancouver project manager Jonathan Eder said: “Terminal 1 holds a special place in our community, physically and emotionally. It’s the entrance to Washington state and Vancouver from the south, it’s where we started moving cargo on the Columbia River a century ago, and it’s long been our community’s link to the river. It deserves to be something special that reflects our unique culture and sense of place, and that’s how we’ve approached the entire process of redevelopment.”

Graham Baba and Greenworks’ plan to transform the historic terminal into a 40,000sq m public marketplace with 10 acres of green space for bike and walking trails and other communal and leisure activities.

The new commercial centre will also include a 160-room Marriott hotel, restaurants, a public dock for cruises, and multi-storey office and mixed-use buildings.

The project, which has been in the works for nine months but which was first conceived in 2016, was first presented to the Vancouver Port Commision in May. Greenworks and Graham Baba unveiled a walkthrough video and renderings of the marketplace on 11 September.

The completion date for the project has not yet been announced.
