Nice to hear that that sort of thing is going well, you know
If you built it yourself, why do you need to "pick up the keys"? Oh wait, you had someone build it for you. 
I wonder how common that is today in the Western world. My grandfather built his own house for his family but I don't know anyone now who's done that.
When our family got a bit big for what was effectively a two-up two-down, my dad did the wiring for the little extension and was involved (though I can't quite remember how much; this was ages ago) in some other stuff. Of course given his job...
