We choose an oval shape because we thought it would look more natural in our backyard. This is a natural not manicured yard which slopes and is surrounded by woods. I (Gr-MaDuck) thinks it looks pretty good.
It is approximately 42 ft x 30 ft (~1050 sq ft)
Next two phases:
Build and hang the gate
(gate and header posts already in the ground),
then attach the wire mesh
1/2" inch galvanized hardware cloth on the bottom (skirted)
and chicken wire on the top.
