Different from most of the designers receiving academic educations in the field of interior design, Mr. Cherng, a dentist and designer, learns most of the knowledge of interior design by himself except when learning fundamental graphic drawing and space design. The indoor public area, a place built for living room, dining room and multi-functional space, shows the style of both simplicity and gentility by furnishing with exposed-concrete walls, purple ceiling, and wooden floor. The statement of “the interior design presents the space integration” has become the spirit when planning the configurations, space variations, and storage functions. The vivid colors and lights, and simple style have built up the interior space the blank infrastructure which is pure, delicate, and modern. In the meantime, the large color wall and a number of antique artifacts have connected the individual items, the design generating the harmonious but unique atmosphere which combines the modern and history.
