eshezo you can't have two houses at this time on any production shard .

So to answer your question. Once you build/trade/buy a new home you have less then seven days to clear out your old one. Anything that is in the house after that time will drop to the ground (unless you sell/trade/give it to someone else).

As to how to move it.. lots and lots of packies (if you have any good friends that comes in handy too ).
