To craft the Crimson Bookcase for Balthazar DragonThorn (in Dragonspyre), you need a Housing Crafting Station. After purchasing the recipe from Toshio, look at the recipe and you'll see a bed within the gear (below the stopwatch). The image within the gear indicates which crafting station you need.
Toshio is the crafting adept of Mooshu and also sells recipes. He works in the Jade Palace area, standing by the exit to Hametsu Village. When you ask about recipes, he first shows you his Useable items - click on the yellow arrow in the upper right to get to the Housing items. There you will find the Crimson Bookcase recipe.
