We just finished an outdoor kitchen project that was a lot of fun to build. Kitchens always have tricky aspects, but we came up with a lot of solutions to make this one work well in the outdoors.
For exterior cabinets there are only so many good options, and the lead times on stainless cabinets for example are ridiculously long. Here we build a frame for our countertop out of steel. This was way cheaper than stainless cabinets and it is also structurally as strong as can be and will hold up well over the years outdoors. We installed a 3 cm granite countertop and a stainless undermount sink. We kept the sink small because the countertop space will be useful than the sink space since this space will be used more for entertaining than regular dining.
The steel frame underneath the countertop provides storage space, but we needed a way to conceal the space for aesthetic reasons and still leave the space accessible. We used the exterior grade cement siding with PVC trim on treated plywood. All elements will hold up well outdoors and the look matches the adjacent exterior. The panels are hung on z-clips, so they lift right up and the space below can be used for storage.
We notched the panel to allow the passage of a natural gas line to service a gas grill. We hooked up a 5.3 CF fridge that provides a lot of room for drinks and food for the grill.
In the Spring this will be one of the nicest rooftops in Capitol Hill. This was a fun project!
