We just finished a built in bookshelf and window seat for book lover in this 1924 bungalow. The old book shelves were full and over loaded. We matched the decorative trim work existing in the house and ran it across the top of the bookshelf. We edged the shelves and front in vertical grain fir. It is a wood that would have been used at the time the house was built. There are less expensive woods that we could have used but fir is a strong wood that it easy to work with. The bottom shelf is a bit taller to accommodate some art and larger print books. There were some challenges in building straight and square on to the old lath and plaster walls which we were able to work through. We finished the book shelves with a low VOC oil based paint. We wanted a tough finnish that would stand up to books moving we have used it on other trim work projects. A latex paint would ware and may stick to the book covers.The window seat has a heating vent that directs out the front. We built a few decorative panels for the front. It may become the new favorite place for the cat and the homeowner.
