Plans for a Brick BBQ Pit?

Question:Does anyone have any sites to offer that have plans for a brick BBQ pit in which I can have two to three cooking shelves and maybe a built-in oven or smoker adapted to survive Canadian winters?
I will use a propane BBQ in a pinch, but I am a true BBQ fan who thinks Charcoal is the only way to go, so keep that in mind, folks.
Thanks in advance for any advice!!

Answers:
Well I did a bit of a Google search, and I came up with a few plans. Thanks for the idea - I might have to try this myself!

http://www.backyardspaces.com/barbeque.h... - 8 BBQ plans and a how-to tutorial. Being Canadian myself, I think the covered one might be what you're looking for. :)

And then of course, if you do a Google Image search, there are many blueprint images - not sure if you can get much out of them, but here - http://images.google.com/images?um=1&tab...

Hope that helps!
