Are the post set into the ground? If not you may want to tie it to the ground somehow, as narrow and as tall as it is a small wind could blow it over during a storm.
Looks like you are doing a good job, and I am passing along info I learned the hard way.
Thank you for the info, actually due to space and weather if on just a foundation and or leggs, i took that into consideration, there will actually be anchors on each side ( front and back)the leggs are down about 8 inches or so,. I anted more room for the outdoor pen/run and didn't want the area consumed with just the house.
