SAMPLE PLAN: Use the drawing above as an example of the key elements that should be shown in the plans that you prepare for review. Please provide an “existing” and “new” plan to show what is changing. In some cases, the entire floor must be drawn for context if the kitchen is expanding or if it impacts adjacent rooms or spaces.
