Working Detail: 10 Hills Place by Amanda Levete Architects
[WORKING DETAIL 10.09.09] Facade
10 Hills Place − The facade was fabricated using 7m-long, 140-1,470mm-wide extruded aluminium profiles that were pre-stretched and bent according to our 3D model. These were sprayed offsite with a highly durable silver gloss metallic paint from Awlgrip, specifically used for painting yachts. The aluminium extrusions form a tongue-and-groove system.
Each profile was clamped to a circular aluminium support, allowing for the rotation required for the fixings on the curved profiles. These supports were fixed to huge galvanised steel fins cantilevered from the primary structure, forming the gentle curve of the eye-shaped windows. The fins also support the high-performance, low-ion, double-glazed self-cleaning units, the largest of which measures 2.8 x 2.8m.
Their size and weight meant an internal supporting structure was also required. Instead of a steel section, we proposed a triple-layered, laminated, curved glass fin. The sculpted interiors to the windows were constructed by Windsor Workshop, which fabricated a CNC timber ribbed frame covered with 6mm flexiply. Areas where tight curvatures were required were created using polystyrene blocks, hand-shaped on site. The entire surface was then covered in coaxial fibreglass matting and coated in Jesmonite plaster with a smooth Sto render finish. This was painted with Keim Ecosil, reflecting daylight deep into the office space.
