Before you consider purchasing any bespoke wardrobe, you will need to make a few key decisions first. The term "bespoke" is a word commonly used in the United Kingdom to describe something that is custom or handmade, which means the bespoke wardrobe you choose can be built to your needs and desires. This means, of course, that you will need to first decide what your needs and desires are. Measure the space in which you intend to place the wardrobe, and think about what you will store inside it to get the clearest picture of what size and shape you will need.
Once you have determined what kind of bespoke wardrobe you want in a general sense, it is time to research furniture makers in your area. An Internet search or a quick look in the phone book should reveal several furniture makers in your area; it is best to visit them if possible so you can meet them in person and see other pieces of furniture they have made. This will give you a sense of the furniture maker's building style and ability level. Choose the furniture maker you are most comfortable working with, and the one who will give you a high quality product at a fair price.
The builder will probably ask you many questions about the type of bespoke wardrobe you want built. Be prepared for such questions by doing a bit of research ahead of time; think about the materials you want your bespoke wardrobe to be made from, as well as any specific designs or features you want included on the piece. If you want the wardrobe to be made from wood, as most people do, be sure to research the different types of wood available for construction, as this will have the single biggest impact both on the strength of the finished product and the appearance.
It may help to take a look at some prefabricated wardrobes at a furniture store to get an idea of what some common features might be. Think about aesthetics of course, but also consider functionality: determine if the wardrobe will be large enough to contain all your clothing and other items, if the items will be easily accessible, if the unit will fit well in the room in which you intend to place it, and so on. You can combine features from many prefabricated models to create a design that is the best of all models.
