Feng shui problem: is it good to build only partial houses instead of main houses in my hometown?

It is possible to build a main house without building a wing, but building only a wing is a taboo, regardless of subject and object, and it is suspected of usurping the role of master, which is a taboo of geomantic omen. Big murder is bad for the master. It is best to build the main house first, then the wing, and see whether it is suitable to build the East House or the Westinghouse, and finally the courtyard wall. If the owner belongs to the golden destiny, the Westinghouse will be built; if it belongs to the fire of life, Shui Mu will build the East House. The so-called four lives in the East and four lives in the West are divided.
