I've used Worldcraft in the past, which is the editor that came with the first versions of HalfLife. I did model my house (which wasn't build yet) in it, and included several nice 'breakable' things like windows, openening doors, and even breakable walls. Being able to copy stuff, I actually modelled the entire block (4 houses) with simple gardens and stuff.
After showing it to my girlfriend how our house was going to look like, I shot it to pieces with my shotgun. And yes, she still lives with me:-)
Did make a nice multiplayer level too.
