Kuznetsov stove
A pretty complex

A workshop by Igor Kuznetsov and Alex Chernov with process photos and drawings.
Complete layer-by-layer drawings, but a complex design with lots of precise brick cutting needed. You probably need to be experienced in masonry to follow it without handholding.
Bell with dead-end benches MHA
workshop by Peter van den Berg with photos and drawings.
A simple design with the few critical details explained, and firebox design and construction covered thoroughly elsewhere in the same website.
