Thanks for all your helpful comments and suggestions. I have decided to do a 10x20(which is the largest I can do without a permit). It is barn style which will give me some additional above storage.
I may be along time before the inside is finished, but for right now just need the space to begin moving fabrics, shelves, bookcases etc.
Money naturally is an issue for me along with almost everyone I know.
I am going to do a diagram to scale to try and figure out the best use of the area available. :mrgreen:
