An outdoor grilling island is a great way to create a custom cooking area without the expense of special-order appliances. Here we take a standard off-the-shelf grill and adapt it to island life.
Step 11: Find Center of the Board Measure 6” from the end of the board with measuring tape. Next, add a mark close to the center of the board (around 4”), which will be the total length of the decorative end piece. Repeat on the opposite end of the board to make a total of two end pieces.
Size up the base. Measure the width and depth of the grill, making sure to account for any items (i.e., gas lines) protruding off the back. Add 1/2" to each measurement. This will be the size of the opening created for the grill. Next measure the distance from the ground to the lid and subtract 2". This will be the countertop height. Next determine the total width and depth of the island. A good starting point is to multiply the grill width by three. This will give equal countertop area on both sides of the grill. Take the grill depth and add 6 1/2" to achieve the total depth.
Create the vertical corners by joining two pieces of 1x4 pressure-treated pine with pocket screws or face-driven wood screws. Subtract 3.75" plus the countertop thickness (usually 1 to 1.5") from the overall countertop height to determine the lengths of the verticals.
Add a 1x4 edge band around the top frame to support the countertop. Optionally, sheet the base frame with plywood if adding operable doors and storage in the island. Attach the base, verticals and top frame with four wood screws at each corner. Turn the completed frame over and install furniture-leveling feet at each corner and 2' on center across the back.
Consult a local countertop fabricator to select an easy-clean countertop material that will stand up to the elements. Once the material is selected and the lead time established, ask the installer to template the island frame, adding a 1" overhang around the perimeter. Be sure to account for the thickness of any cladding in addition to the overhang.
The face of the island can be clad in a range of materials from metal to masonry or wood. In this case, reclaimed pine studs left over from a renovation were cut down into 3/4" strips and then installed with 15 ga. finish nails driven into the top and base framing. If installing a different material, such as masonry, it may be necessary to clad the exterior with sheathing first. Take this opportunity to decide if operable doors for storage in the base are necessary.
