Clerestory Garden at Naka-Ikebukuro Park

Mixed-use building in Tokyo beside Naka-Ikebukuro public square. Fire regulations capped aluminium framing at 2.2 m, leaving clerestory windows above. The facade steps back to form a planted clerestory garden, adding greenery without reducing leasable area. By day, light filters through seasonal planting; by night, tenant lighting glows through the foliage. Upper floors hold a maisonette linked to the garden through a loft, binding commercial and residential life into a porous section.
