A quality life is one lived outdoors..
Building your own outdoor kitchen from cinder block cuts the cost of a professional installation by more than half, and the before image here shows exactly how straightforward the structure actually is before the finishing materials go on.
The foundation is the first thing to get right. This kitchen sits on a paver patio, which works as long as the pavers are set on a compacted gravel base deep enough to handle the weight of a full block structure. If you are building on bare ground, pour a concrete pad at least 4 inches thick. Do not skip this step. A shifting base will crack your countertop and pull your joints apart.
The structure itself is standard concrete block, also called cinder block or CMU, stacked and mortared in a running bond pattern. This means each block overlaps the joint of the one below it, which is what gives the wall its strength. Plan your layout on paper first, designing around the actual dimensions of your appliances. Grill inserts, side burners, refrigerator drawers, and sink cutouts all have specific rough opening requirements, and your block coursing needs to account for them from the ground up.
Fill the hollow cores of the blocks with rebar and concrete grout as you build. This is what turns a stack of blocks into a structure that can handle the weight of a stone countertop without flexing.
The countertop here is dark granite, cut to fit and set in a mortar bed on top of the block. Granite is the right choice for outdoor use because it handles heat, moisture, and UV without deteriorating. Have it cut by a stone fabricator with the sink cutout already done. Trying to cut granite yourself without the right equipment is not worth attempting.
The stacked stone veneer applied over the block exterior is a thin manufactured stone product, not real stone, which makes it light enough to apply with standard tile adhesive. It comes in panels or individual pieces and is available at most home improvement stores. Use a polymer modified thinset rated for exterior use and seal the finished surface once it cures.
Plumbing the sink requires running a water line and a drain. The drain is the harder part if you do not have an existing line nearby. A simple solution is a dry well dug a few feet from the structure, filled with gravel, and connected to the drain with PVC pipe. For the water supply, a frost free outdoor faucet connection works well in most climates.
Gas line work for the grill should be done by a licensed plumber or gas fitter. Everything else on this build is well within DIY range, but the gas connection is not a place to save money.
The whole structure from first block to finished countertop is a long weekend of work for two people with basic masonry skills. The patio, pergola, and raised beds surrounding it complete the space but can be built separately before or after.
