Can I build a toilet in the front yard? Affect feng shui?

Hehe, it's not a big problem. It depends on the distance, far from affecting. If it is close, you can add a partition wall or something, which is of course more professional and meticulous. As my friend said above, it depends on the date of birth of your parents and so on, and it will also affect the relationship between your house and the surrounding environment. I suggest you don't care too much ... everything is positive, harmonious and noble. ..............................
