In this small space

This is what I was talking about. As you clearly can see, we use the galley for two very different type of purposes. But it just has to be like that I guess? Living on 20 square meter (215Sq Ft) doesn't give too much of space to play around with. How do you other people do who's living aboard? I have understood that it is impossible to mix fillers and other powdery substances outdoors while it's windy, but I would like to keep this precious area of the boat safe from those toxic things as well. Any type of advice is welcome. /Taru
