Moonstone was designed as a roof top extension to the existing restobar at the Crystal Palace Hotel. The ambience of the restaurant is defined by a play of shadow, light and movement achieved through intricately designed perforated metal roof panels. The idea was to recreate the dappled effect from under a tree canopy as sunlight filters through several layers of leaves. Each roof panel is composed of two perforated metal sheets separated by a gap. The overlaid shadow of the two sheets creates a dappled shadow on the floor and tables. As one walks through the space, the expanse of the roof is animated by the moiré effect created by the slight variation in the perforation patterns on the two superimposed panels. We experimented with leaf imprints on the cast concrete tables and introduced hanging seats to extend the idea of being under a large tree canopy.
