There was something I didn't like about 1001bit, but I can't recollect what it was. I'll give it a try again to see what it was. As far as VisuHole, it just makes cutting the holes easier. It doesn't do the framing like HouseBuilder does for doorways and windows. I was looking for something along that lines. Now it does look like if I have to use it, it would be a lot easier to design the framing parts manually, but it will still take up more time than what a computer can figure out and do the stuff for ya. Edit: Found out what I didn't like about 1001bit: Doesn't do framed arches, just standard door and window frames, which HouseBuilder already does and IMHO does easier.
