The National Association of Home Builders estimates that an outdoor kitchen can add as much as 130% of their cost to the purchase price. Other creditable sources believe in an even higher return on investment than any other product in the “outdoor renovation” product category. CNN Money, About.com and Remodeling Magazine support that outdoor kitchens nationally return 100% to 200% of the improvement cost. As with any improvement, the ROI (return on investment) formula works providing you design and build a kitchen that is proportional to the home value and location. The initial cost of outdoor kitchens varies from $10,000 on the low end to $50,000 or more, depending on the layout (size of outdoor kitchen), materials, quality of stainless steel components chosen, and upgrades such as built-in LED Lights, stereo systems, and fire features
