Rainbow City is located at the south side of the Qiantang River, Hangzhou. The project is on the opposite side of the bank where the national tourist attraction district is located. The site area of the project is around 220,000m2 and a GFA around 470,000m2 is provided in the development. Natural environment surrounds the site. The project, which targets middle to high-income buyers, is the top priority pilot residential project in Hangzhou for the 21st Century.         The residential community is planned in a number of building groups. High-rise plays a major role for the northern part, although some medium-rise and multi story blocks are located on the southern part. The central visual corridor, which also acts as the axis of the site plan, links up several regional communities. Moreover, all other planning elements are connected through this axis.         The master planning makes full use of the change of level between the riverside and the basin in the south to form a high level podium. On top of this podium are two groups of high-rise buildings. The lower level of the podium is used as carparks, clubhouse and commercial facilities. In addition, school and kindergarten are located at the southeast side of the site, which is more independent from the main development.         Master layout plan is divided into northern and southern portion. Northern portion is built along the riverside with sea view as the main theme while the southern portion is expanded from the theme axis. Among each cluster is a private courtyard. The master plan is designed in such a way to facilitate hierarchical management and phased development.
