Can't help but might have an idea for ya.
I gave a present to a couple of friends of their house in 3D.
Not 3D printed - but that could be a way for you to go - but I drew out the shape of their house (it was quite boxy so not too difficult unlike The graces ) and then built a card box of that shape.
Then I printed off photos I'd took of each side of their house and scaled the photos stuck them on the house and it looked pretty good.
The fact that I'd gone to all that trouble really made an impression.
Just a thought if you get stuck -I'm sure your dad would appreciate the effort.
