1. Design Planning: Size, Layout, Location and Budget Considerations
Design and planning for a BBQ island involves a thoughtful approach to size and layout to ensure the space is functional, comfortable, and appropriate for the intended use. Here are key considerations for size and layout and budget:
Size Considerations
Available Space: Measure the total available space in your outdoor area to determine the maximum size for your BBQ island.
Scale: The island should be proportional to the size of your patio or backyard. An oversized island in a small space can be overwhelming, while a small island can look lost in a vast area.
Work Zones: Allocate space for different zones: hot (grilling or cooking), wet (sink), cold (refrigeration), and dry (prep and storage).
Seating Area: If you want a bar or seating area, you’ll need to add approximately 15″ – 14″ of depth to the counter to have clearance for stools or chairs.
Traffic Flow: Ensure there is enough room around the island for comfortable movement and that the placement does not disrupt the flow of traffic through your outdoor space.
Appliance Size: The size and number of appliances you want to incorporate will directly influence the size of the island.
Utility Space: Leave room for hidden utilities, such as gas lines, electrical wiring, and plumbing, if you plan to include a sink or refrigeration. We will review the above in detail within this article.
Layout Considerations
Work Triangle: As with indoor kitchens, the work triangle principle can apply to outdoor kitchens, positioning the grill, sink, and refrigerator to form a triangle that facilitates easy movement between them.
Wind Direction: Consider prevailing wind directions to prevent smoke from the grill from blowing directly into dining or seating areas.
View and Interaction: Orient the BBQ island so that the cook can engage with guests and enjoy the view. The grill should typically face the entertainment or dining area.
Sun and Shade: Be aware of the path of the sun and position the BBQ island to take advantage of shade or to avoid the intense late afternoon sun.
Accessibility: The BBQ island should be easily accessible from the indoor kitchen to transport food and supplies back and forth.
Counter Space: Ensure ample counter space on either side of the grill and other appliances for food preparation and serving.
Safety Considerations: Maintain safe distances between the hot zone and combustible materials or structures; include adequate space for a fire extinguisher and for guests to move away from the grill if necessary.
Storage: Include enough storage for tools, cooking utensils, and other essentials; plan for dry storage as well as potentially refrigerated storage.
Location Considerations
Proximity to House: The closer the BBQ island is to your indoor kitchen, the more convenient it is to transport items back and forth. However, it shouldn’t be so close that smoke or fire poses a risk to your home.
Utility Connections: The location must be suitable for accessing or installing gas, electricity, and water lines, if your design includes these features. The cost of extending utilities can be substantial and needs to be included in the planning stage.
Weather Exposure: Consider the exposure to elements such as sun, wind, and rain. This may determine the need for additional structures like pergolas, awnings, or windscreens to protect the area and make it more comfortable.
Ground Surface: The existing ground where you plan to build should be stable and level. If it isn’t, you’ll need to include ground preparation in your plans.
Privacy: Depending on the layout of your yard and neighboring properties, consider how the placement of your BBQ island will affect privacy for both you and your neighbors.
Views: Maximize the enjoyment of the outdoor kitchen by positioning it to take advantage of any pleasant views your property offers, or conversely, to screen out less desirable ones.
Local Regulations: Be aware of local building codes and homeowners association rules, which can dictate the placement of outdoor structures and the need for permits.
Budget Considerations
Material Choices: The cost of materials can vary widely, from luxurious granite countertops and high-end stainless steel appliances to more budget-friendly options like concrete counters and refurbished appliances.
Size and Complexity: A larger kitchen with multiple appliances and features will obviously cost more than a simple grill station. Decide on must-have elements versus nice-to-haves based on your budget.
DIY vs. Professional Installation: Doing it yourself can save on labor costs but may not be advisable for complex projects involving gas or electrical work. Mistakes can be costly to rectify.
Appliances: The cost of appliances can quickly add up. Choose the appliances that you’re sure to use. Sometimes, opting for a model with fewer features can significantly reduce costs.
Utilities: The expense to run gas, water, and electrical lines can be one of the most significant costs in an outdoor kitchen project. If on a budget, consider designs that minimize the length of utilities or opt for propane or solar-powered options.
Landscaping: Altering the current landscape to accommodate your BBQ island could add to the cost. Plan to utilize as much of the existing space as possible to keep landscaping changes to a minimum.
Labor Costs: If hiring professionals, labor can be one of the largest expenses. Get multiple quotes and references for any contractors you consider hiring.
Permits and Insurance: Ensure that you budget for the cost of any necessary permits, and check with your insurance provider to understand if and how your outdoor kitchen will affect your homeowner’s policy.
Contingency: Always include a contingency budget of at least 10-20% for unexpected costs, which are common in construction projects.
Once you’ve addressed these considerations, you can begin to sketch out your BBQ island, keeping in mind how each element will fit into the space. It’s often helpful to use garden hoses or chalk to outline the dimensions of the island on your patio to get a better sense of how it will physically fit into the space.
This also gives you a tangible way to walk around the proposed layout and make adjustments before any construction begins. It’s also advisable to consult with a professional designer or landscape architect, especially for more complex designs or when utilities are involved.
By taking the time to thoroughly evaluate location and budget considerations upfront, you can avoid many common pitfalls and ensure that the project stays on track and meets your expectations.

Building a BBQ island can be a rewarding project that enhances your outdoor space, but careful planning, adherence to safety standards, and attention to detail are essential throughout the pro
Prefabricated BBQ island options:
5.5 Ft – 9 Ft BBQ Islands (In-line options)
If your space allows for 5.5-9ft total, you’re looking at a 2-3 cabinet set; you can add a beverage refrigerator, your grill cabinet on one side and another cabinet of your choice on the other, as shown below. If covered with stone, you can fit in a drop-in sink or side burner through your cabinets.
 |
There are many more options that are available for smaller outdoor kitchen sizes. We suggest you have a look at all of the 5.5 ft – 9 ft cabinet combination options within your budget and send us an email or give us a call to discuss your thoughts, be it for your imminent home projects or future dream kitchen. |
Here you also have 2 simpler, shorter options which both look fantastic. They are 2-cabinet sets, one being the grill cabinet.
9 Ft – 15 Ft BBQ Islands (In-Line)
| If you are lucky to have a little more usable space to fill, you might want to include a few appliances within your design such as a refrigerator for food or beverages, a dishwasher or a full grill. For example, the below outdoor kitchen in white includes a 2-door cabinet, refrigerator, 3-drawer to organize those BBQ utensils and tools, a grill cabinet with storage and another 2-door. Appliances can be installed within the cabinets through custom stone countertops. This set spans over 11.3 ft. |
 |
Below, this gray 4-piece budget friendly set includes a grill cabinet, 1-drawer plus 2-door cabinet and a 2-door cabinet. The second set in white includes a 3-drawer instead.
L-Shaped Outdoor Kitchens
If you have room, you can create a nice open design with an L-shaped outdoor kitchen simply by adding a corner cabinet. The corner cabinet itself has a hexagonal shape, which offers a lot of storage space within. Another option is to go with a kamado corner cabinet, to add an additional grilling option to your outdoor grill island. The kamado cabinet also offers additional storage space underneath.
Again, because they are modular cabinets, they can be positioned in any combination you wish; if, down the line, you want to make some quick changes to your outdoor kitchen, you can reposition them.
There are multiple available options in L-shaped kitchens on our website.
4 Life Outdoor cabinets come with powder-coated front panels in white or gray colors. If you are looking for a seamless look all around for your BBQ island, we do offer the side and back panels which are a popular option by our customers.
| In the next example, the customers were looking to furnish their deck with an L-shaped kitchen. They had enough room for a 10-piece and chose to include a kamado cabinet for multiple grilling options. A corner cabinet also works.
The kamado and corner cabinets come with the stainless steel countertop though if you choose a stone, you would simply remove it. |
 |
| The 5-piece shown below excludes the stainless steel countertop. Multiple appliances are included within; a drop-in sink, refrigerator and a side burner. The countertop is made of stone as a contractor would be able to cut through it. |
