We understand customers might have a tight space or possibly want to enclose our products or build structures around them. We strongly recommend that you receive our products first and build after you have the products. We are not responsible if our product does not fit your pre-built space and sometimes our dimensions can be slightly off or it could be a factor of your walls, floor or how you assembled. For this reason we suggest you receive the product first and then proceed to build and not the other way around, this is the smarter way to proceed.
