Rural houses were all built on auspicious days. Do you need to break ground again when the foundation has changed?

There is a saying: if you don't completely dismantle the foundation and only modify the completed part, and continue to build houses, it can only be regarded as housing reconstruction, and there is no need to choose another auspicious day. If you want to start all over again, even if you are building a new house, you should choose a good time to start a new day. Since it is to build a new house, it is recommended to start all over again to avoid the foundation of the house not forming a whole. Although a period of basic work and materials were omitted, a defect was left in my heart, that is, the foundation was incomplete.
