How much would it cost to make a badminton court in my backyard if I want to get a synthetic surface, and if I just want to clear the grass and level it out.
I want to make one after winter.

Also any tips to help against wind?

high ceiling+garage=profit

if it was me, i would make a universal court with a sleeved hole for a basketball hoop and maybe the dimensions for other games such as pickleball.

great wind blockers are arbeveta bushes (probably didnt spell that right)

any game where you hit something called a shuttleCOCK is gay
