Modular assets can be a little confusing at first, but once you have them in the right place, everything becomes so much easier. They are widely used in the industry and no wonder. In addition to saving time and resources, they allow for optimal handling. Changes to some parts affect all buildings at the same time, which makes it easier to make corrections and the like. Imagine that you've modeled several buildings and now you've decided that they should be shorter or taller, or have wider windows... so this geometry nodes setup was made to make it all easy. Includes simple models and materials as a starting point for you.

Please, read the documentation for more details.
