This project is a residential planning case. Because the homeowner prefers dark colors, the designer has chosen black and gray natural mineral slabs and black mirrors as the main color scheme of the shared living area, combined with the linear design of horizontal stripes, adding a sense of three-dimensional and layered space. Also, teak wood panels and natural wood veneer embellishments have eliminated the oppressive feeling generated by the dark color configuration. At the same time, a sense of tranquility and seclusion is also delivered.
