Got the power turned off, so we lifted the carpet, drilled a hole into the basement and ran 2 big honking extension cords from the basement thru the hole to our living room so we had a space heater, TV and stereo.
In one place we lived, we had what we called "THE VOID". We had a living room window that went out, and it basically was a 4 story enclosure maybe 8 feet by 8 feet -- picture something like an elevator shaft that went down to the ground, but it was just enclosed by other exterior walls (I'm guessing some additions somewhere caused this, it couldn't have been planned). You could see down to the ground but there was no way to get there from the ground level. We threw all our trash out the window when we moved out.
