The place to start when you are designing your dream kitchen is with a dimensional diagram of your kitchen space. On a large piece of graph paper, draw the outline of the kitchen space, including any doors or windows that you will have work around while you design your kitchen. Accurately mark where your plumbing and electrical supplies are located. You can move plumbing and electrical supply points, but this involves more time and money, and it is always easier to accommodate existing service supplies into your design, if practical.
Another aspect to take into consideration is the appliances you will be using in the kitchen, and this is greatly dependent on the number of people in your home. If you have a large family you will require a larger area space with more effective equipment and storage. Items, such as dishwashers and refrigerators, must be chosen with care as they can enhance your kitchen design. To do this you must properly plan your kitchen space and identify how much money you can comfortably spend.
