Law Courts in Arezzo, Italy1 www.euro-inox.org Euro Inox 2010Plan of 1st upper storey scale 1:750Section scale 1:750L A W C O U R T S I N A R E Z Z O , I T A L YA new four-storey law courts building in Arezzo, located in a park close to the townsMedici fortress, houses courtrooms and officespace. A glazed bridge links it to an adjacentneoclassical building a former hospital which after renovation will offer additionaloffice and archive capacity. The naturalistic curved lines of the new build-ing are inspired by both the lush vegetationof the park and the mediaeval fabric of theold town, protected on one side by thickwalls and opening on the other to gardensand green open spaces.The north faade of the law courts, clad withdark-grey granite and rising up from its ellip-tical footprint like part of a cone, presents a virtually fully closed aspect. Contrastingwith this, on the south side a two-part curvedlattice of stainless steel protects the almostfully glazed faade behind it from solar radi-ation in summer and cold winds in winter.The closed, matt faadeon the north side con-trasts with an open-stylesouth side where the louvres of the stainlesssteel screen reflect thesurroundings and gen -erate an ever-changinginterplay of light andshade.

The upper sections of the roughly 20-metre high frame, which is made entirelyof stainless steel (grade EN 1.4301), are tiedback either to rectangular pipe sections onthe building or to the cantilevered floor abovethe second upper storey.The horizontal stainlesssteel louvres are madeup of a series of shorterangle profiles.

In winter, however, the screen admits thelower-angled rays of sun into the interior ofthe law courts.
