The design concept is based on the keywords: “radiance”, “streamline” and “cymatics”. These keywords are developed from the co-living space, 52 HERTZ. The concept is named after Salute Apollo, which means appreciating the god of sun. The site is located near the sea therefore the residents of the co-living space are able to enjoy the sunrise and sunset every day. Moreover, it would be like a ceremony between the people and the sun every day. Furthermore, you will figure out that there is a dormer and some sun-looking ceiling designs seen in the perspective. Coral orange, salmon orange and laurel green were applied as the main colours of the interior. This is because these colours are gentle and harmonized with the scenery during the day. During the night, residents will feel warm when staying indoors because the colour scheme is just like the sun. In additionally, warm colours can give a feeling of home to all the residents living in it.
