The interior space is about 330 square meter with elongated structure, long corridors, and a large terrace, therefore the layout must be carefully considered. In addition, the line structure of interior window was also complicated; in order to narrow the space for light interaction, the concept of green house was adapted, the function and line was designed by using different materials, to form an open space with delightful living landscape. All functions were designed to hide between the wall lines in the corridor, leaving the simple and pure background. The light atmosphere at night creates a quiet and unique environment in the corridor, which touches our inner desires. All the colors, proportions, material details were designed by the designer with full authority due to the good interaction between the owner and designer. The whole case design was completed with integrity with high quality and value. "A container of sunshine delivers the concept of green energy."
