A small question now when I found a spot for a tower with wings, have tried it out on Tcenter and it worked out.

this doesnt matter what house Iam placing but if I already have a house and place a new one my old house will be condemned (or how it spells) How long time do I have to move all my stuff from the old house to the new house? is it hours or days? Dont wanna risk to loose my stuff ))
