We have a Casita (as they are called in St. George... means "little house" in Spanish) attached to our house. It's like a mother-in-law appt. It is a bedroom with it's own bathroom and closet. It shares a wall with the rest of the house, but has it's own outside entrance. When we moved into this house, we couldn't quite decide what to do with it. At first, we thought it could be a play room for the boys... they would have all of their toys, video games, etc. out there. Then, we just decided to make it an office/craft room. My husband is a full time student and he also works from home occasionally, so we figured he needed a somewhat quite place to work.
About 90% of the space is mine.... and 10% his... but he spends 9x as much time in there as I do. My hobbies just take up way too much space.
This is the view when you walk in the room.
The large printer belongs to my husband, but I use it a lot for posters for primary and other craft projects. I love maps and found this fun colorful map at a garage sale to hang above it.
