steven holl‘s ‘ inversion’, presented on occasion of milan designweek 2013, features digitally cut 21 million year old limestone from a quarry in lecce, italy. a five axis CNC mill carved a composition of voids out of the rectangular blocks based on an interpreted watercolor by holl. six stone volumes, weighing 1133 kg each frame a shallow pool of water that mirrors the renaissance loggias of the cortile 700 in universita degli studi di milano, a contrastingly rhythmic repetition of columns and modular arches. each form is conceived as a sectional slice that reveals reversed solid-to-void relationship, further inverted in the mirror-like pool. at night, iguzzini-designed LED strip tubes provide a warm yellow glow to the cuts in the 1.2 meter-tall monuments while a misting system by teuco guzzini further imbues the space with a ethereal scattering of light and reflections. from the INTERNI hybrid architecture and design exhibition in milan, the sculpted stones will be flown to the united states to be installed in the architecture of the new, steven holl-designed performing arts center at princeton university.
