We have encountered similar problems. This year, all the mobile homes of a project department were completed and accepted. Their project manager invited a Mr. Feng Shui to have a look. It turned out that the project manager's office opened two doors, forcing me to seal one. By that time, all the workers had been evacuated. Hmm. How interesting .........
You can also go and have a look, preferably before building a house, otherwise it will be very troublesome in case of any changes!
