When working on
@Tom Tee posted:Obstacles? Nah.
One of the obstacles I had was the max. sq. ft. limit in my township. That is why I used 45 degree angled corners. The space out side of my 84" radius curves was wasted anyway so why not angle the corners so I can extend the overall length of the building several feet.
Plus the "raised dog house" gave me 36 square feet of yards.
