It's really nicely done, maybe just some fresh cloud white paint from Benjamin Moore? It really adds a lot of texture and interest.

Do you want to keep the wood floor? It is rare to see wood floors as garage floors. I've seen homes like this moved onto pour basement slabs (same concept as pile foundation...but with a basement instead of dirt. If you want to keep the wood, then there has to be a way to keep the wood off of the concrete. An 18" crawl space (dirt covered with 6mil poly sheeting or cement) is always an option. The 18" crawl space would have to be cross vented/heated properly. This is for "keeping" the wood. Flooring. I'm not sure what has to be done to remove the wood floor and have the building sit (joists and all) on concrete. Remove the joists and you have plenty of stability problems. You would need to speak with a local architect/building engineer who has some knowledge of what you are trying to do, soil conditions, etc. to get this right. In theory it can be done (we've just landed a small car on a comet...we should be able to put an old building on a cement slab)...I'm wondering about the expense to get it there (excavation + soil stabilization + concrete + piles, etc).

Gloss finish! What'd you decide to go with?

Hi Michelle - It looks like treated pine to me, and looks as though it has been recently built. If you did nothing it would fade to a grey colour within 6 months or so. This would probably blend in with the house quite well, and you wouldn't have to do a thing! Otherwise I would stain it - there are lots of stains on the market - see if there is one you like. A dark one would create a nice contrast with the house and make the fence look more like a feature. Good luck!
