What is being referred to here is that you will not be able to use any Kli that you have built because you will not have the possibility to make a Zivug de Hakaa on it, a right kind of connection. Others will live in this house.
It is impossible to use a Kli, a house, with an intention that is not justified, while others will partially be able to use it in their own way. They will ultimately bring you to correction, to you being able to return to your house, but only after going through a very lengthy and painful journey.
