My wife loves that I am in the hobby because it keeps me occupied and believe it or not "alive".
I have a large 16x10 ft room dedicated for just my hobbies and another small room for my firearms and reloading equipment.
Sharing your hobby would be a good thing if possible, my wife comes up with some awesome ideas and loves my rigs all over the house.
That's the way it should be. Plenty of space for everything. But in your area the houses are a bit smaller and you have to use it for multiple things sometimes.
