The Biorefinery is sited atop a roundabout in the London borough of Hackney. This particular location was chosen for its history of pollution and Hackney’s pledge to achieve net-zero emissions by 2040. The project displays a fantastic collection of detailed sectional, perspective, and axonometric drawings. The tower’s form is defined by a unique set of tapering tubular forms, driven by its function as a combination of mineral-recovery, biogas-production, and waste-water-recovery facilities. This set of programs is infused with office and residential spaces, gardens, and atria. The building’s apex is designed as a machine of steel enclosing mechanical elements, reminiscent of both Paris’ Centre Pompidou and the guts of a typical oil refinery.
