Transforming a 1980s office megastructure into a fossil-free residential ecosystem.
Located along one of Brussels’ major urban boulevards in Evere, Everside converts a former office building into 177 apartments, a commercial ground floor of 1,300 m², and shared collective spaces. The project rethinks a building originally designed around car access and isolation, transforming it into a climate-adaptive residential environment.
The project begins with a radical decision:
retain the existing concrete structure instead of demolishing it.
The original frame is preserved as a carbon resource and reconfigured to accommodate housing units with private outdoor spaces, natural daylight, and cross ventilation. A lightweight prefabricated timber crown extends the roofline with terraces, loggias, and planted zones while respecting the original structural rhythm.
The envelope is completely redefined through a solar-responsive façade system following a 3.60-meter structural grid. Triple glazing, external shutters, thermal mass, automated night ventilation, and passive house principles eliminate the need for fossil fuels and air conditioning. Two air-source heat pumps feed a shared heating loop.
The transformation extends beyond the building itself. Car dependency is reduced by half, paved surfaces are replaced with planted infiltration areas, and the underground levels are reopened to bicycles, shared mobility, and collective services. New trees, gardens, and stepped landscapes transform the former residual perimeter into a climate-responsive public realm.
Materials are selected according to circular principles, integrating reuse strategies, dry-assembled systems, and pre-demolition audits to anticipate future disassembly and adaptability.
Everside demonstrates that a generic office megastructure does not need cosmetic renovation.
It can become a resilient urban ecosystem.
Not preservation through nostalgia—
but transformation through regeneration.
