We Specialize In Outside Kitchens

Take Your Cooking Skills To The Great Outdoors!

Another way to extend your space during SIP is to consider an outside kitchen. With this addition, you and your family can forgo navigating crowded parks and beaches in order to gain the benefits of being outdoors.


We can build you a simple grill station. Or, if you like, let's get creative and build you a custom, state of the art kitchen with all the bells and whistles.
