Can you use the fortnite building technique on a self made game in UE4?

Hi, I am creating a game for me and my friends to play and I was wondering if i am able to use the fortnite building technique (including the editing of the structures) to be placed in my game. I am thinking that I am taking the idea from the creators of fortnite, but at the same time I don’t believe they own the creation of it. Thank you for any help!

But you’re not. Ramps and platforms were popular back in 4000 BC.

You can always add a legal tag in order to lure an Epic representative.
