Situated on Stockholm’s Blasieholmen quay, The Glass Lens is an adaptive reuse intervention within a historical harbor warehouse from 1910. The project acts as a mediator between the National Museum’s monumental front and the site’s rugged maritime origins. By reclaiming a neglected fragment of the old harbor long obscured by infrastructure and demolition threats, the design rejects progress through bulldozing, arguing instead that the most sustainable future is one that “reforms” existing skeletons to meet contemporary needs.

The architectural centerpiece is a 165m² high-performance glass volume inserted into the original timber skeleton to house a café & bar. This “Box-in-Box” strategy creates a thermal envelope while preserving the warehouse’s embodied carbon. Transparency defines the spatial experience: one side offers a curated view into an active maritime workshop, a living homage to the site’s shipbuilding history, while the opposite facade is peeled away to reveal an 85m² covered seating area.

Through tectonic honesty, original rafters and columns are celebrated via carefully integrated LED lighting, highlighting the contrast between weathered timber and structural glass. By restoring this missing link in the city’s pedestrian fabric, the intervention re-establishes the quay as a public space for both labor and leisure.The Glass Lens ultimately transforms a “forgotten” maritime front into a vibrant social anchor, transitioning the quay from a decade of restricted access into a new era of historical continuity.
