I didn't choose the new path I am headed down but some things are falling into place really well.
I am now faced with a difficult task... deciding what the new boat shop will look like. The space is about 12x40 with a fairly low roof. The floor is concrete slab. It looks like I need to strip the material from one wall. There are the remains of a water supply pipe and drain near the outside wall. Don't know where they go but may allow a small sink. There is natural gas in the house and only about 10 feet between the house and the garage/shop building. Oh, yeah, this means that at some time in the future I can have a heated shop where I can do fiberglass work during the winter! I'm thinking about splitting the space so I have a primary 20x12 workshop and a unheated 20x12 storage area.
The garage is more like 16x40 and I may do something similar with it. You can see a split in the slab where the original 24 foot slab was extended. I may replace that wall so I end up with a 16x16 shop space separate from the garage. Again, with a gas fireplace ($40 off craigs list...) I can heat some of this space during the winter.
What should I be thinking about in designing this space?
