Urban erosion & biophilic textures

The skin of the building pulls inspiration from the natural process of erosion, a powerful force driven in the Pacific Northwest by glaciers, rivers, and oceans that carve away at the landscape beneath. 9North’s entire northern façade is “eroded” away with stepping decks that wrap around each corner. The façade’s transparency is dynamic, based on a gradient, increasing in density towards the south as it reaches the property line. Composite wood soffits contrast with the extensive glass and highlight shifts in massing, while stone plinths and fiber cement panels provide natural texture.

Decks all the way down

Along with a large, shared rooftop amenity, every floor has additional decks and terraces, providing tenants a direct connection to fresh air.

9North Landscape Architecture

From elegant stormwater features to green street retail terraces, 9North encourages a connection to the outdoors at every level.

Green street terrace

A stepped setback on Thomas Street – a city-designated green street – creates room for vegetation and retail terraces, forging open space that the public and building tenants can enjoy.

A stormwater showcase

Showcasing the flow of stormwater onsite, an elevated runnel feature on the rooftop terrace displays water cascading down a sheet of perforated metal. An additional ground-level stormwater planter along Thomas Street integrates public bench seating. All streetscape planters have curved corners to maximize traffic circulation within the site and to create a softer feel from all directions.
