Default Gazebo/firepit overhaul

So the house we bought has, what we’ve been calling a gazebo/firepit. About 14’ x 14’, with a pit in the middle, and a screen, cone chimney, and a stack.

There are a few issues with it, the roof is shingled, but it’s flat, so the snow and water collect really quickly.

Even with the firepit roughly centred, they offset the sheet metal pipe with two 90 degree elbows, which really affects the draft. It’s also just a single wall pipe, so the heat transfers quick and we’ve actually had a small fire at the roof to put out.

So after looking at it a few times, I think I’ve came up with a plan to change a few things.

The existing stack is also only 8” dia, with the two elbows, and the height of the ‘screen’ all around the fire, getting draught can be tough, so smoke doesn’t all go up the stack, and part of the gazebo seating area ends up getting smoky.

My plan is to rework the four sections of roof to give it some slope, likely about a 3:12, just enough to get the water running down the shingles. Change the route of the stack so that it’s a straight run and eliminate the 90’s. And increase the stack to likely 10” diameter to also help increase the draft.

looking at the first pic and seeing your pathway which appears to be raked concrete... but it might also be a mat of some kind...

reminds me of the old redneck joke that said "I put carpet in the bathroom... the wife liked it so much she had me run it all the way to the house !!

Amazes me someone would put a flat roof on that building, especially in Alberta. I could maybe see that in AZ. Sounds like you have a good plan on getting it functional.

At first glance, I would guess the elbows are there to avoid issues with the complicated framing at the centre directly above the fire pit. To take those elbows out will mean a significant change to the framing structure.


I see at least two attempts at framing the roof. Was the building originally an octagon or circle? Looks like someone changed the side facing the first pic to rectangular.

It would be a fun long weekend project to redo the roof, but might mean a complete tear off and redesign.

I think the pit was first, concrete pad second, and the roof was last. The roof is shingled like a cottage style roof, there are four triangles of shingles that meet in the middle.

Someone here in the past has been a joist hanger fan, there’s other places where they are used around the house.

I’m hoping to cut the four triangles of roof apart, adjust the pitch, and rework the centre to allow a chimney opening. I’m ordering some pipe, hopefully today, which is where the metal fabrication in this thread will come into play.

When I saw that chimney it was "Good grief!"
Have you considered moving the firepit off center to be right under the chimney?
I think 8" is enough.

I saw one of these last week, a truly Albertan solution to old used grain bins.

I’ve thought of different options, since I arrived last fall, every time we were having a fire it gave me time to study things and design solutions in my head.

The plan is to use a piece of 12-14” diameter pipe, and make it a centre framing hanger for the roof, and create a hole in the centre for a chimney as well. Each roof triangle is about 60-70 square feet, so even with shingles no more than about 300 pounds each. There’s enough guys that hang out here for fire nights that I should be able to get a couple sets of hands to lift and move things around.

The two pieces of pipe should be ready for me to pickup tomorrow afternoon.

Then I’ll be able to actually finish dialling the mill in and try it out!

FYI Gerry, the town of Trochu has at least 2 of these gazebos in green spaces in the town. They used the now deemed too small 1250 bu bins for them. The only major difference is the fact that they used different (Westeel-Rosco) brand bins.

Started back on this project today. First step was to cut a 3” long piece off one end of the 10” pipe.

Next I cut that piece into four parts, which I’ll use to make a ‘clamp’ for the pipe. Click image for larger version
