I want to keep doing woodworking all year round, and have decided to build a piece on to my workshop (and add a furnace), which was a single car detached garage when I bought it. It is 14’ x 24’ and I want to add a piece on 12’ x 16’ deep. I guess my question would be more directed to woodworkers in colder climates like mine (eastern Canada). I think the easiest way to build the base would be similar to a deck ( a 2” x 6” frame), it is raised up a bit and the floor would be approximately two feet above ground level.
To keep the heat in, I was thinking of adding plywood to the bottom of the floor joists (essentially boxing them in) and then having the open area spray foam insulated before adding the flooring sheets.
Has anyone ever done something like this, or if not, do you think it would be the best way to do the base? Pouring a cement floor and then adding a two foot high wall would be much more expensive, and more difficult than the method I’m thinking of.
Your ideas would be appreciated.
