Looking for pony wall plans and examples

[mbear]

Hi - I am working on designs for a platform for a 16 foot yurt with 8 foot walls. I would like the walls to be taller so that I can put in a sleeping loft. Do you think that pony wall is necessary given that the walls are already 8 feet? If I do opt for the pony wall, I would love to look at blueprints/plan/sketches to give me a better sense of how to build it. If anyone has any to share or thoughts and tips, I'd be appreciative.
