react-grid-layout looks like a good candidate, but it seems like it lacks a way to customize/add rules for positioning elements to prevent "stacks" of elements. Imagine a user models a brick wall and you want to prevent users from stacking bricks above each other (prevent bricks stack bond and allow something like running bond brick pattern)
