A bunch of American garages are the same way. There are lots of 2 car garages in suburbs that only have enough empty space for 1 car, if any at all. I suspect that this may be more of a widespread phenomenon than I had realized.
Growing up, I'd hear of all of these big tech companies that got started in some guy's parent's garage. I considered my parent's 1 car garage: mom complained when she couldn't put the car in it, and the rest was filled with tools and the lawnmower. No way a company other than a car shop could get started there.
Apologies to any sensitive readers from Finland.
In my case, no sauna and previous owners redid the garage into hall/utility (laundry) room/big bathroom and a small unheated workshop. Guess where the clutter lives, heh. :/
I guess I'm a sensitive Finn :)
