Design Pattern-builder Pattern)

To put it simply, I am a real estate developer who wants to build a villa, but I don't know how to build it (simple wall building, low level ), I also don't know how to design it (Building a few rooms, a few good-looking doors and a high level). So I need to find a civil engineer who will build walls and a designer who knows how to design it, I also want to ensure that the Migrant Workers listen to the leaders of designers, and the designers themselves do not work, just give commands, here build a wall, here build a door, so that the migrant workers start construction, finally, I can ask migrant workers for a house. In this process, there is nothing for a designer, except for the design and command in his mind, so the house is also required for migrant workers.
