There’s a welcome transparency to the legal process in Madrid now Technal has rolled out its Geode-MX curtain walling for the city’s new 6800m2 Fuencarral police HQ in the El Pardo district of the city. Voluar Arquitectura has created a bold form of cantilevered glass-fronted boxes that protrude from its double-skin envelope, break up the facade and provide raised terraces and patios. Random perforations on the outer skin’s mesh screens control the depth of field and light penetration, providing a degree of privacy and solar shading throughout the day; and creating a constantly changing facade. Internally, a full height glazed atrium at its centre unifies all the buildings’ different administrative functions and spaces.
