Type 1: Courtyard Community                                                                                                                  This type of community is quite similar with the expansion part of Barcelona with a larger scale. Residential buildings are used to keep the boundary of the urban street and contain the city park inside. Citizens share high-quality public space with the standard housing status.

Type 2: Opening Block Community                                                                                                          This type of community is built around a urban park. The urban streets are continue and break into opening community. Every block has its own neighborhood. Every unit has higher living quality with big living room and balcony.

Type 3: Single House Community                                                                                                            Several single houses are built in a community instead of along the street. Community has its own street system which is narrow and  closed. Every family not only enjoys its own house with green space but also lives in an active and safe neighborhood.
