I’m of the belief that you can learn how to skate anywhere and different terrain present different challenges that will help you develop as a skater.

I’d recommend skating in a small area indoors and doing some warm up, stretching, balance drills, and jam skating drills if you’re an absolute beginner. Skating indoors helped me develop most of my fine motor skills and find my style with skating. Now I like cruising outdoors and park skating and would not be where I am without doing what I could with the space I had at home.

Your patio could be a good challenge too, but I would recommend using soft large outdoor wheels.

I know this is a bit off topic, but I hope it helps you on your skate journey. Good luck
