You want an outdoor smoker/bbq right up against the house. .................: ( Off the top of my head? I'd say bad idea.

A lowly gas grill used three days a week all summer at the far end of an open deck, will do a great job of coating that side of the house , all the screens and windows with a layer of grease and smoke residue. And that's if all you grill is fish, chicken and steak........and nothing ever catches fire.

Bad idea IMO a smoker is a huge stink maker let alone the smoke that needs to be removed. A BBQ in a 3 season room needs to be vented big time and IMO you need both of these outside that space so maybe a small open air deck with a cover to protect you when you are cooking .

@ Jan I think they wanna put all that indoors not outdoors.

I understand it to be UNDER a covered/open three side patio that places it directly at WINDOWS to the actual home. Not a great idea, in any scenario. He is referring I believe to an "outdoor room" but no ability to powerfully vent.

"a covered 3 season room, open on the south and west sides.

The north side of the room is access to the house, and the east side is
centered with 2 house windows. The east side is the only side I can put
a bbq, sink and smoker."

The bbq however, may need to be centered on the windows on this same wall."

The problem with a grill up against a framed wall is that over time, the heat coming off the back of the grill dries out the wood framing like a kiln and you eventually get all the elements for a great fire. Fire Magic, one of the lines we carry, calls for 14" of clearance from the back of the grill to the face of the combustible wall, with a steel stud framed wall covered with a non-combustible substrate in front of that. Unless you're planning on that (or the wall is non-combustible material) I would hesitate to do this. Also if the windows are close enough to the grill that you can't use a hood, that seems like it's setting up for a whole bunch of other issues.

Something similar to this is what I had in mind. So this would not be "indoors" but not completely outside either because of it being covered, and only open on 2 sides. It's a 3 season room/back porch. What you see on the right hand side of this pic is a fireplace that splits the open southern exposure.

Sounds like it is doable to have the grill along the wall/windows here if precautions are taken with non-combustable materials in the wall, but not advisable. Also, good point about the smoke residue and grease forming on the windows over time, as that would certainly be a hassle to clean.

I'll look into indoor BBQs and see what kind of options that presents, but I'm assuming most options will require some sort of venting directly above, a la a hood, which as you can see wouldn't work with this setup. If that's the case, I need to re-think this entire back porch, and placement of the outdoor kitchen.

I wouldn't feel comfortable building what's in that photo. That deep under roof, there's no way I would do a grill without a hood. And I'm no glass expert but I'm guessing 80,000-150k BTUs (depending on the grill head) isn't great for the window or whatever's on the other side.

As I said:) Not a great idea at all . It belongs in the great OUT doors

No hood works if it's not positioned directly above (30" typical) the cooker. When you have any cross ventilation it's a bigger challenge. You can compensate for variations to the typical by increasing the width and depth of the hood. In a commercial kitchen you will find the hood up at 78"-ish but the chef is actually standing under the hood it's so deep.

This will be a disaster waiting to happen. I'm trying to find pictures of the job I did a while back, they put a bbq close to the house and burned down the entire side of the house including entire deck.

This is just a bad idea.

Indeed: ) I like BBQ,,,,,,, not that much lol

Here they are:

Yes......... RE THINK to the entire cook function outside the "room". A bar inside? Fine! Who the heck wants to sit in any smoke. At all.

Just because you see it in a picture does not make it a good idea, listen to what has been said.You could do something like this attached to the space

@pelagic what did you wind up doing? I have a similar situation and was wondering how it all turned out for you and any learnings you had along the way. Would love to see pics!
