This is multifunctionality at its best: apartments that can be offices and turned back into apartments. Multifunk applies equally to both functions. ANA Architects analyzed the needs for both: different floor heights, exits, entrances, construction - but especially the difference in installation requirements was a big tackle. The solution lies in the absence of mechanical air-condition. Sunscreens and –blinds combined with natural ventilation through the façade made the deal. The construction is integrated in the façade with columns in the centre of the building. Glass roof parts together with gaps in the floors allow daylight to enter into the heart of the building.
