Building the bookcases for my office built-ins was the fastest part of the process! No need to buy pre-built, you can easily build your own and customize their size to your space with a few basic tools. And I used pre-finished plywood so the inside was already sealed once built 🎉. It was my favorite time saver on this project. Find the build plans on https://housefulofhandmade.com/diy-built-in-storage-cabinets/. #diybuiltins #diybookcase
