Balanced space between Instansiated Objects

So, hey Guys, Hope yall Doing Good and well!
I am currently making a sort of infinite 2d vertically scrolling Jumping game , where i will use pooling to instansiate the Bricks/Platforms that Player can jump on, But sometimes the Platforms get too close to each other and overlaps, which isn't what i want. How can i make it so that, there are enough spaces between them.Thanks!
