62. Farmer and Neighboring Sons

Easy Medium Hard Extreme

A farmer wants to sub-divide his farm between his 4 sons and at the same time retain his own piece of land in the middle for himself. His farm should be equal in size, but different in shape to those of the sons. The 4 farms of his sons should be equal in size and shape. He also wants his farm in the middle of the big farm to have them all 4 as neighbors!

How would you achieve this by adding 16 sticks?
