Choosing a Site

• If you already have a deck or patio, you're ahead of the game; your outdoor kitchen won't cost as much to implement if it encompasses a pre-existing foundation. Have a professional evaluate the structure before proceeding, however. Your space might need extra bracing to hold the additional weight of an outdoor kitchen.
  
  Place the outdoor kitchen as close to the house as possible---in particular, near your indoor kitchen---to minimize time and energy spent moving food and supplies between the two rooms. Take into account the potential site's exposure to the elements as well as any flammable hazards overhead such as tree limbs, trellises or a patio roof.
  
  

Construction Considerations

• Modern kitchens require, by definition, water and electricity. If you've chosen a gas grill, you'll need access to a gas line as well (keep in mind that gas grill inserts must be enclosed in a non-flammable material). Sinks will require proximity to a clean water supply and a drain. You will also likely need to obtain a permit for any electrical or plumbing additions. As with any project of this magnitude, check with local zoning authorities before moving forward with your plans.
  
  When constructing cabinetry for outdoor use, take into account how well your chosen materials will withstand the weather. Use pressure-treated lumber and countertops that are similarly weatherproof. But even with weather-resistant materials, the better shielded they are from the elements, the longer the kitchen will last without need for repairs.
  
  

Design for Comfort

• Outdoor kitchens should be designed with nods to functionality, comfort and aesthetic appeal. For instance, a small outdoor refrigerator may ease food preparation effort considerably: You'll be able to store mayonnaise and other perishables to have on hand during the cooking process. (If you decide to install a refrigerator, choose a stainless steel model designed to fit under the counter to protect it from the elements, and keep it locked when storing items long term.)
  
  A well-placed sink is not a necessity, but will usually prove to be a great convenience, especially compared to using a garden hose or a trip inside for water. Some modular units offer grills with side sinks, along with other features. Evaluate which design will work best for your needs, space and budget.
