The Inbisa Tower case study permits us highlighting those subtle design strategies that make a building with four apparently identical facades be so suggestive.
The facade is organized from several overlapped grids. Pillars and slabs cladded in aluminum draw the main order: a grid of the scale of the structural system. Over this grid, some mullions define a second order of the scale of the windows. This second order runs literally over the first grid, regardless of whether what is behind is blind or transparent, breaking the rigidity and scale of the main order.
