New member's yurt plan

[Pacific Yurts]

Your plan looks very nice. Venting for the bathroom and cooking exhaust could be mounted into your partition walls, and using a 'downdraft' exhaust fan, could actually vent through the platform and then outside. Plumbing vents can go through the yurt wall using a boot flashing (available at your local hardware store) in a similar fashion to the stove flashing. Just make sure the top of the flashing slips under your top cover valance.

A good place to mount the air handling unit for your ductless heat pump would be on the edge of the landing at the top of the stairs. This would face it into the main living space and it should be out of the way. The electric and refrigerant lines could come up through your platform and into your partition wall so they are out of site.

Good luck with your project, it sounds like it will turn out nice.
