This winter I want to build a treehouse for the kids.

Any experience, advice, tips, inspirational pics, resources, etc?

I am particulary wondering about what luck I might have in avoiding interaction with the authorities. The location selected is in some evergreens at the edge of our property, which is a ivy slope overlooking the sidewalk and road. The treehouse will be nestled in among the overhanging trees and ivy, closest point about 7-8' from the property line (sidewalk). The platform will be about 6' above nearest ground level, and about 12' above sidewalk level. I'll get the platform up, put up some temporary railings, paint it all dull brown to blend in, and get some ivy started up on it. Then think about adding a playhouse on the platform later. It won't pass code for a "deck" or a "house" or any other structure I've looked up in the Portland City regs. Partly due to the minimum setback being 10'.
