Extreme home makeover

I had just gotten into Harry Potter and was planning out my own mini turret, Ravenclaw house bed, and wand collection.

When I was younger I was really into space and books so I constantly went back-n-forth between the two. Then I had the great idea of Doctor Who planet of books

Then I had this idea of having a TARDIS that was fused to the doorway of another room, which of course would be decorated to look like the inside.

What about a TARDIS on an empty lot of land that leads into a foyer designed as the control room underground? And the rooms are spaced in a weird loop so it looks like the corridors of the TARDIS!

And bits where there are mirrors, a sort of Gallifreyan rotating key thing to get into certain rooms. When I become rich and famous, this is what I shall do.

Can I room with you? I'll pay my share of the rent!

When I become rich and famous you won't have to pay. Just buy the food. We could probably invite people to it and make a killing.

Sweet! But what if we lose our guests...?

That's their problem. When we find them, we will feed them to our pets. Any suggestions for which pet to get? Other than our k-9 replica.

Hmm definitely some adapose (a fat hairless cat?) and in the library we could claim that there are those things that I can't spell. Also a dog dressed as a Dalek?

That would be good, imagine a little collar for the dog that, instead of jingling all the time, says exterminate. I could see that getting annoying though.

What about it's a button (or remotely activated) so it's just a regular collar with a little recorder stuck to the inside

That is good, so we could control when I makes the noise.
