Luv Quilts and Cats

I think I would go with the addition. You would be connected to the house, but still in your own space. And you can close the door when you don't want to be disturbed. In an addition, you would probably have 4 straight walls. In a she shed, two of the walls might not be tall due to the pitch of the roof. I do love She Sheds. I live in New Hampshire and I am not sure I would want to leave the house in the winter to go sew in the shed. That's why I would go with the addition.

I thought just crossed my mind. Is it possible to build an enclosed walk way from the second story of the house directly to your room in the garage? If possible you could put a sliding glass door in the second story room of the house, or french doors, and have a walkway to the garage. You would probably want to enclose it some how to avoid the wet weather and snow. Just a thought.
