CAN, in collaboration with Nina Shen-Poblete, was commissioned to design a temporary window installation for the Royal Institute of British Architects (RIBA) Regent Street Windows project at 76 Portland Place in London. The architectural installation reimagines the building's glazed street frontage through a ghosted silhouette of a historic Georgian terrace, celebrating a lost London streetscape through ornate window openings. By deliberately blocking up these apertures, the design references architectural tax history—specifically the historic Window Tax—and explores themes of impermanence, adaptive reuse, and layered urban history within the city fabric.

On closer inspection, the facade reveals CNC-machine-cut breeze blocks featuring exquisitely ornamented surfaces crafted through digital fabrication techniques typically reserved for precious stone and marble. By elevating the humble breeze block into a high-end, sculpted building material, the project challenges material hierarchies and sustainable resource perception in contemporary architecture. The spatial narrative continues into the interior reception area, featuring custom furniture design in the form of a soft sofa upholstered to resemble rigid foam breeze blocks, fabricated in-house to seamlessly blur the boundary between structural architecture, materiality, and interior product design.
