Interior Space and Exhibition Design Light Box Residential House by Jun Zheng Light Box is a residential interior design for a three-story townhouse in Chengdu. The rectangular plan is 15.5 meters long and 7.8 meters wide, with a total area of 400 square meters. Decoration is reduced to a minimum, and open blank space is kept so that daylight and nature reach the living areas. A patio beside the first-floor kitchen and tea house was formed from part of the original garden. Joints between solid wood veneers are controlled to one millimeter, and small gaps are left where stone meets wood to support long-term use.
