The Seattle studio designed the 18,500-square-foot (1,719-square-metre) centre for Recompose, a company founded by Katrina Spade to offer an alternative to cremation and burial.

Slated for completion in 2021, the facility is expected to be the first of its kind to offer human composting on a large scale.
According to Recompose, it will also be "the first facility in the world to provide a sustainable option for after-death care". The company highlights a number of ways that human composting is more sustainable and environmentally friendly in comparison to other options.
