So far I used the dining table in our living room for the hobby. This is not ideal for various reasons (setting everything up, stowing it away, working with resin, etc.). In May I asked my landlord if there is a spare room in the basement which I could use as a workshop... and he said "yes, there another room that is empty" and so I came to my dedicated hobby dungeon.
It took me some time to clean it up and arrange it properly. It is just 1m wide and it was a little challenging to set everything up in a way that I can store (and get to) everything and to have sufficient seating space at the desk. I have it in use now for almost two weeks and I am more than happy. I have enough space space to sit comfortably to build, convert and paint. All the tools and paints are in arms reach and I can leave everything when I am done for the day without having to worry that the kids might eat a hobby knife or sniff some resin dust.
The dedicated hobby space also allows me to finally look into airbrushing, something that simply wasn't possible in our living room.
