Our new master bedroom will have a sloped ceiling because it's under a gable roof. We'd like to make good use of the space under the eaves with some built-in shelves and drawers. Someone suggested that it might be possible to use some pre-made drawers as a starting point, rather than having it entirely custom built by a cabinetmaker. Has anyone done this? Any ideas on where to look for the right kind of options? Is this like an ikea hack or something that we'd look at a kitchen cabinet catalogue? Or are we better off going fully custom? Any ideas on costs of various options?
