An outdoor kitchen installation in Livonia, MI moves the cooking out of the house and onto the patio, and it asks a lot more of the patio than a grill on wheels ever did. 

Gas, power and sometimes water have to reach it, the base under it has to survive a Michigan winter, and every appliance in it sets a dimension the masonry has to match. Those decisions arrive in a particular order, and the order matters more than the style.
