There are a few different types of wine cellar kits you can buy. There are small pre assembled wine racks or larger wine racks that come in separate parts. You can store your wine rack in any room ( kitchen, basement or a temperature controlled cellar room). The other option is to use some variation of a wine cooler. You can get them in all different shapes and sizes. Most come pre assembled and can be shipped right to your door. Another option would be to read a how to build a wine cellar book and then purchase the materials.
