Smoker Design Help

[Rufneck]

I am building an outdoor kitchen on some rural property and want to incorporate a smoker into the design. The kitchen cabinet / countertop will be free-standing and will have a BBQ grill, a sink and I intend to incorporate a smoker. I have found a wood burning smoker that I can have made for me and then I would have the mason just build around it but I am thinking that an all brick/mortar smoker would be better than a metal one that's been built around.

I have seen several smokers that are built into countertops but the ones I have seen are narrow and around 6 feet tall and I don't want that. What I want is a scaled down brick/mortar smoker. Does anybody have a proven design they can share with me? The countertop on my outdoor kitchen is 36" tall and the width of the smoker can be up to around 42 or 48" wide so I think I have adequate room.
