House not finished yet, move is coming up - tips requested!

Get yourselves a large storage container. It costs about 100 € per week.... Our neighbors did that recently when they completely renovated and converted the entire upper floor. Or do you have a room that will be completely finished? And can the door be taped off and closed? Otherwise, the stuff will dust up so badly that you'll regret it later.

Under no circumstances put furniture into a house where [Spachtelmasse] is still being sanded..... Under no circumstances. You will not be able to seal or cover it properly!
