Do I need to buttress my side walls?

The inside of the dome seems fine, today I will proceed with insulation ... thanks for the encouragement..

I am almost finished with the chimney, ( only the top cover is left ). I tried to keep the whole weight to the bare minimum in order to avoid the buttressing after all. It was a really hard work cutting those bricks but at least I managed to achieve what I wanted ..

This is the most beautiful WOF oven chimney I have ever seen. Well done!

I am planning to build around the ss pipe ( full length photo below ). While researching on the net I noticed that there isn’t a single WFO with a round brick chimney out there, so I was wondering is there a reason for it( complications on building it ) or just a matter of aesthetics?

Say where did you get that really long chimney pipe?
