This is the garage my dad built at our cottage (yes the garage is larger than the cottage, which shows our priorities). It's 20 x 40 feet, with the back 20 x 10 being a games room with a pool table, darts, arcade machine etc. This past summer we put an extension off one side another 10 feet wide and 30 feet long. we use this new room for all the wood working equipment (table saw, miter saws, drill press, dust collector etc) to keep the dust in one are. We also have a half floor above with a cheap winch on a barn door rail that we use for storing the dirbikes and lawn furniture in the winter, and the snowblower and other crap in the summer
My dad is a mechanic at home, so he put in a 9000lb hoist at the cottage so when he retires and moves up there, he can still fix local cars and do projects
Here is an interior pic, it's changed i bit inside since this was taken
I'm really lucky my dad is such a hands on guy, or i'd never have a shop like this to work in. that's why i really appreciate my parents.
