Has anyone built a model house formerly?

I am in title 8 and i need to build a model home by Thursday. I don't own much time so it has to be assured to make. Has anyone built a model house earlier and have any tips or pointers? I hold a 95% average and i don't wanna screw it up now. Please, even links to places where on earth i can find out how to build it with would relieve!!! It needs to be 30cm x 30cm so not too big.... HELP!!!

Answers:    If it's something small for a project... I would suggest using a cardboard box! Paint it and if it have to have rooms... cut up little pieces and stick them surrounded by. If you don't see what I'm getting at... watch "13 going on 30"... the house he give her but smaller and made of cardboard! Hope it helps and virtuous luck!
