A few weeks ago my dad turned 64. He told me last year that he would like to have his garage (he has a very large garage where he works on his hobby: restoring classic cars) in miniature. I didn´t copy it exactly (it would have been a large building then :-)) but made a roombox with a few things in it.
It took a lot of time, but my dad is worth it. It is not as messy as his real garage, but maybe he will start cleaning his real garage :-).
