Draw you kitchen's basic shape. Be sure to include any major structural features or obstacles that may affect where cabinets can be installed. Graph paper is not necessary as long as the drawing is clear and accurate.

Mark the location of all windows and doors and any other openings in the space. Follow this action by marking the locations of existing plumbing, or the locations where plumbing will be moved. Notate the locations of power outlets and light switches. Then indicate the location centers and width of for your refrigerator, stove, sink, etc. 

No room entries, appliance doors, or cabinet doors should interfere with opening of appliances. Facing cabinets need enough room between them to have both doors opened simultaneously. (at least 1/4" from adjacent object, not including cabinets) Place a filler between the cabinet and the wall to ensure space to fully open the cabinet door. (at least 1/4")Wall cabinets are typically hung 18" above the countertop. An island should have at least 36" of space on all four sides. Leave room between the sink and cooktop for preparation when they are adjacent to each other. Be sure that inward opening windows are not affected by sinks placed below it. House the dishwasher close to the sink to make loading and unloading easier. A sink or oven placed next to a wall limits workspace and disrupts work flow while cooking. A range should never be placed at the end of a run because of safety.
