How do you want to use your new space? What appliances or design elements should be group together for optimal functionality? For example, an avid home cook may want his or her spice rack at the ready when cooking on the stove in the new kitchen, or a bookworm may want to create a small reading nook and bookshelf in the new office. If you plan to add furniture or new doors and windows to the space, also consider how the layout will need to accommodate those additions.
