If you can reorganize and equip your kitchen for maximum utility, you may not need to blow out the walls to gain square footage. Start by replacing space-hogging shelves with cabinet-height pullout drawers 8 inches wide, containing racks for canned goods and other items. "You're getting three or more horizontal planes where you might otherwise get only one," says Louis Smith Jr., an architect with Meier Group, in Ann Arbor, Michigan. You could easily shell out a few thousand to outfit cabinets with upgrades like dividers, pull-out pot trays, and lazy Susans, but you'll save many times that amount by skipping the addition you thought you needed.
Look at your countertops next. “Limited counter space is always problematic in tiny bathrooms,” Maykut says. Often, you're left with nowhere to set a cup of tea or lay down your curling iron. One creative solution for gaining space is choosing a custom countertop. While most bathroom configurations place the vanity next to the commode, Maykut suggests “extending a narrow ledge of countertop along the wall behind the toilet.” This otherwise wasted space is just right for a supply of tissues or an assortment of toiletries.
