I love the Ovo products but I agree with the other posters, you need to have several living spaces connected together to make it big enough.
also, condensation can be a problem if you don't have air conditioning. in the summer it can get stuffy and in the winter it can fog up, making the bedding damp.
so if you have air conditioning i'd say go for it - if you don't, maybe try getting a Ferplast wire cage which has tube holes for adding on.
