![AQSO arquitectos office. Prefabricated facade made of lightweight concrete forming an ruled surface. Each of the windows corresponds to a hotel room.](https://aqso.net/cms/files/projects/1703AHL/AQSO_arquitectos_office_Shoreditch-hotel-low-angle-detail-check-board-windows-bended-concrete-767x511.jpg)
The parametric design of the façade, consisting of geometrically different parts which are nevertheless the result of a mathematical transformation, requires each part to be accurately prefabricated.
The black concrete panels that form the frame or shell enclosing the volume are triangular pieces of glass-fibre reinforced stained concrete. This lightweight material can be anchored to a steel structure, allowing the façade to be easily assembled.
The faceted, curved surface of the façade generates an interesting effect of reflections and nuances thanks to the semi-polished finish of the black concrete.
