The cost of custom built-ins and cabinetry will vary depending on the materials you choose and the style of your wine cellar. You can have cabinets built in a variety of styles, including traditional, modern, or rustic. Additionally, since they're customized to your specifications, they'll fit perfectly into any space. The price will also depend on the size of your collection and how much storage space is needed for it. If you need more than one set of shelves or racks for different types of wines (such as white wines versus reds), then this may add additional costs as well.
