The HIL building has shaped architectural education for five decades, forming a layered assemblage of alterations, atmospheric traces, and constructive robustness. Its history reveals a remarkable capacity for adaptation, making it a fitting point of departure for an approach that continues existing qualities while integrating future demands. At its core lies the question of how HIL can be transformed spatially, structurally, and technically into a future-ready condition.
The building’s legally and structurally feasible extension by two additional storeys offers the opportunity to redefine its overall form and create additional space for diverse uses. At the same time, the existing curtain wall façade comes into focus: its limited porosity and restricted natural ventilation call for further development that combines energy performance with improved indoor climate—without negating the existing fabric.
Closely linked is the question of circulation: the originally open movement system has been significantly altered by fire safety regulations. Revisiting the egress strategy—for example through façade-based escape routes—could restore the spatial generosity of the original circulation concept and reactivate transitional spaces.
Continuing to build on HIL means understanding the building as an evolving organism, whose spatial and material resources are mobilised to accommodate new forms of learning and working, and to shape its architectural, technical, and atmospheric future with precision.
