At the Tsinghua University in Beijing the boys- and girls- dormitories for domestic students are separated. When on a date, the boys need to wait for their girlfriends outside of the girls' dormitory. However, they are ashamed doing so. Besides that, crows resides in the trees surrounding the dormitories and their shit causes a problem. Therefore the place could use a pavillion providing privacy for the waiting boys and protection against the crows' shit.
The pavillion is situated at girls' side at the conjunction of the boys- and girls- dormitories. It consist of two parts: a concrete landscape and a roof. The concrete landscape evolves into two benches and walls, secluding an inner space with an entrance from both the boys- as the girls- dormitories. It is covered by a concrete roof.
Where the concrete landscape evolved in walls it is penetrated by glassfibre. On the exterior side the glassfibre is shined upon by the sun, or surrounding lanterns in the night, lightening the dim inner space in a mystical way while remaining the privacy. The concrete is pre-fabricated in parts and casted in polystyrene foam blocks. To cut all the different foam blocks a hotwire is attached to a six-axis robot. Subsequently the blocks are clothed with a fabric for the concrete to mirror the texture. Then the hotwire is replaced by a drill and the six-axis robot makes the holes for the glassfibre, which are designed in a certain pattern accentuating the center of the inner space, where the boys and girls meet. Eventually the drill is substituted by a grab tool which is used to weave the glassfibre through the holes once the foam blocks are put in place. The concrete mixture contains a bit of red pigment to give it the desired color.
The roof protects the inner space and glassfibre penetrated concrete from the crows' shit and the weather. Because of the hypar form of the roof it is both double curved and comprised of straight elements. Therefore the surface the concrete is cast upon consists of straight scaffolding wooden boards in a concentric pattern, again to replicate the wooden texture in the concrete. The spacers of the reinforcement follow the same pattern.
The roof touches the ground on two places only, where it is connected to a foundation consisting of horizontal concrete beams. The concrete landscape acts as a counterweight of the roof on the foundation.
