Oh, how completely and totally exciting! I'm going to live vicariously through you for awhile - I have neither the land nor the funds for this sort of a project but I sure do have the WANT!
So tell us - what are your plans? What are you going to have in there? How many windows? What sort of lighting? What sort of cabinets? What sort of flooring? What's your square footage? How are you going to finish the exterior? What color(s) are you going to paint it???
I need more info so I can pretend it's mine! LOL
