Interior Space and Exhibition Design Happy Excursion Model House by Z-work Design Happy Excursion is a model house interior in Shenzhen, China, covering about 418 square meters. The exhibition hall integrates wind, light and water to connect people with nature. The flooring carries a blue stone texture that suggests a calm river under the feet of visitors. A three-dimensional wall of Fantasy White Jade stone forms the central feature, and its surface changes as daylight shifts. A skylight panel with a light film creates soft lighting effects. The wooden cabinets are made from selected, dyed and finished wood veneer.
