The SS treatment is actually not stainless steel at all , but a very thin flashing material from a local hardware store, I used an industrial mastic to apply, but it is a .30 gauge aluminum, why ? it's cheap , washes easily with soap and water, and is hardly different from the look of stainless, extremely easy to cut, shape and apply. The range hood is SS, but side by side with the aluminum they look the same, so a seamless match at a fraction of the price. I believe I paid around $ 30 dollars for a roll of 16"x30' , one roll was enough to cover the whole wall behind the brewing system, any seems I used aluminum flat stock, which is also cheap.
The brewery is pushed against the wall normally , but I bring it at least 2 feet from the wall for a brewing session, so no danger of excessive heat to the structure while brewing, my hood design( by depth) allows for this movement, another reason to spend time laying out your thoughts on paper first before building such a compact space.
@ James, I like to brew outside in the elements too ! http://www.homebrewersassociation.org/pages/community/pimp-my-system/show?title=chris-bowens-arctic-brewery
@ Robert , I have no provisions to cook inside my brewery ( food anyway) , outside I have a grill , fire pit , and deep fryer , but also a cottage with a full kitchen within 20 feet of the shed , so I had no need to add additional cooking facilities. I do have a dishwasher under the bar, not sure if you can see it from the pictures or not, this is most helpful for glasses.
Hope this info helps !
