As the guestroom is very small, the open-style design was adopted to maximize the light effect in space expansion. The sunlight splashes through the white sheer onto the wall and floor, with the change of time, creating different shadows and lines as in an abstract painting. Considering the financial cost and design intent, the wall and ceiling are mostly finished by the simplest material, white paint, and the flooring is finished by local materials. While pursuing a pure and minimal space, the details of the design are well crafted. The color transition brings with it the change of materials - reflective glass, matt stone surfaces and natural linen textures contrast with each other; glossy stones contrasting with wood grain gradations enrich the layers and the texture of the space; the scattered pendants illuminating the atrium give the impression of different sea animals happily swimming in a wavy sea.
