I would't do all of those forms at once. It can be a can of worms (right, I get it if some people say it's easy - yeah, it is - but it can still be a confusing affair if you do it all at once). If you wanna do passive (создан...), go for it. But do not try to go for the other stuff too.

I think the OP is confused by the many ways of expressing passive:
Дома строятся. - The houses are being built. (incomplete...not finished)
Дома построены. - The houses were built. (it's complete...finished action)

Right, it's not the "sexiest" example out there. However, you shouldn't confuse reflexive verbs with those forms.

Anyway, I hope the example "kinda" helps.
