There are two caveats however. Firstly you want to avoid clicking build or destroy otherwise you'll atom smash all your lovely wood and secondly you'll want to build it in a secure location to avoid other people doing this. The second little caveat there isn't too bad though as they look like everything else until built.
You can do the same with a number of part built structures to store different objects if you desire and you waste no materials on the storage this way.
It's not an exploit honest
