This a very important question Mr. Bhaand, yes you can dig to the core of earth but please make sure you don’t and can’t dig to your neighbour’s core of the earth. So if you 1000 yards house then dig in your area.
And Gizzy got the right point, you can also build a house in your 1000 yards to the strasophere. But don’t go beyond earth because you haven’t paid for it. I hope that answered your question.
