There was a great story some time back about a HardCore Star Trek fan who transformed his apartment into an exact replica of the Starship Voyager. He later started a company that can help you transform your house (or, more likely, your parent's basement) into the Starship Voyager.
You can see a number of before and after shots at the URL below. They are really amazing.

You, too, can have your very own StarTrek house with the help of the folks at 24th Century Interior Design, the company this guy started after he went bankrupt converting his house into the starship voyager.
