How to split product category page

We want to do a multivendor shop and I would like to divide the product category page into two sections 40/60. There should be a list of products with scrollbar on the left. The right side will be stationary (fixpossition) with a pinned store location on the map (each product will have a store’s coordinates).

Thank you for help in advance.
