I've been wanting for a while (and needing) to put the 1978 BD Whirlpool washer in a separate building-hooked up on its own-it is sitting in my Dad's tractor shed, collecting dust right now-I'd been thinking a nice 8x12 or even an 8x8 of my own to hook up my washer-or any other washer that exists in the world in it-a building to where it can be hooked up all-year-round instead of only in spring and summer. Any suggestions on what kind of building construction is necessary-and that can handle an off-balance washer thumping across the floor?
