I have a building under construction now. It will be a sewing room 20x20, a storage room with a cedar closet 10x12 and a bathroom with a shower,sink,and stool 8x10. I have an electrician drawing out the electrical design for me today. The 30 feet in the back of the building will be for my vintage car and other storage..One day I will try to post pictures...I have tried in the past but it just baffles me why I can't get it to upload.
