construction is underway in milan, italy for the ‘citylife tower’, designed by tokyo-based arata isozaki and milan-based andrea maffei. the foundation consists of a continuous block of concrete which covers 4,260 cubic meters, requiring 42 hours of uninterrupted work to complete. 62 concrete piles measuring 30 meters in length and support the 1,200 ton steel reinforced structural base.

the 63 by 27 meter foundation will uphold the 61.50 by 24 meter building footprint. expressed in the elevation, six office floors are contained within each of the eight vertically stacked modules. encased with a double-glazed skin, the convex facade will be held in place by four inclined struts along the wider elevations. these bracing elements will serve to divert some of the loads from the interior structural frameworks. in 2015, the structure will be the tallest in italy, reaching a height of 207 meters.
