This research aim is to understand the history and transformation of houses in the Chinese post reform era, so in order to compare one scheme with one another, and to interpret their economic and social values, all the elements, dimensions and relations, which constitute the space pattern, must be identified. For this reason, per each selected Vanke’s housing project, I analysed the apartments’ plans, identifying the function of each room, their sizes as well as their configuration, through the use of architectural drawings, analytical sheets and Justified graphs. These descriptions can thus inform the way in which a group of ambient is assembled to form a pattern, rather than illustrating merely the localized properties of any singular space. Therefore, these illustrative and analytical tools, applied to several houses plans, provide us with the possibility to draw qualitative and quantitative investigations of houses attributes.
