The document compares the courtyard design strategies of traditional Beijing Siheyuan houses and the Courtyard House in Singapore. Both designs follow principles of Feng Shui and hierarchy. The Siheyuan houses have rooms arranged along north-south and east-west axes, with the main house facing south. Similarly, the Courtyard House has two blocks in a north-south orientation around a central courtyard. Both designs also use grey brick and tile with green plants to create harmony and ventilation. The inner courtyard serves as a private family space in both house types. In conclusion, the houses show similarities in their vernacular courtyard-based architectural designs while responding differently to their environments.
