How to DIY an Outdoor Kitchen: A Step-By-Step Guide (Part I)
Why Build a DIY Outdoor Kitchen?
Now that school is out and summer is full swing, we have been spending long hours outdoors and naturally (for us) Nick and I are in the full-on planning phase of our outdoor kitchen. If you saw my last post on Outdoor Design trends, you were maybe struck with the statistic on ROI for outdoor kitchens! Outdoor kitchens have surged in popularity, becoming a must-have feature for homeowners who love to entertain, cook, and create lasting memories with family and friends. The allure of al fresco dining, combined with the freedom of cooking in an open, breezy space, makes an outdoor kitchen a backyard centerpiece. But while custom-built kitchens can carry a hefty price tag, building your own offers a rewarding blend of creativity, cost savings, and customization.
We are feeling energized at the idea of designing a space that suits our cooking style, aesthetics, and budget. While summer months can get unbearably hot here, I would say outdoor entertaining is a 3 season sport in Austin. Whether you dream of a rustic cooking station with a pizza oven or a sleek, modern setup with polished concrete countertops and streamlined appliances, the DIY route lets you control every detail. Not only does it save on labor costs, but it also provides the satisfaction of transforming a blank canvas into a functional and stylish space.
Moreover, a well-built outdoor kitchen adds real value to your home. It can become a gathering spot for weekend BBQs, family celebrations, or quiet evening dinners under the stars. With proper planning and the right materials, you can create a kitchen that withstands the elements and stands the test of time.
Planning Your Outdoor Kitchen: Laying the Groundwork for Success
Before you lift a hammer or pour concrete, careful planning is crucial. A well-thought-out plan ensures that your kitchen is functional, aesthetically pleasing, and structurally sound. Here’s how how we approached the planning phase.
Assess Your Backyard Space
Start by evaluating your available space. Consider these factors:
-
Size and Layout: Measure the area where you envision your outdoor kitchen. Look for flat, stable ground and ensure there’s ample room for movement and seating. Avoid overly tight spaces that restrict cooking or dining areas. We will be adding our outdoor kitchen in our covered patio. You’d think this would be very straight forward but our patio is very long and skinny. Surprise to me as I was looking for inspiration online that it is very common for houses to have long skinny patio areas. Anyway, we really had to think through how our layout would work to ensure ample movement in the kitchen area as well as a small lounge space.
-
Sun Exposure and Wind Direction: Notice how sunlight moves across the area during the day. You may want shade during the hottest hours or a sunny spot for cooler evenings. Wind direction is equally important; placing your grill or stove upwind from seating areas prevents smoke from blowing toward guests.
-
Utilities and Accessibility: Is the space close to water, gas, and electrical lines? Planning for these early will save headaches later. Also, consider proximity to the house—a close location makes transporting food and drinks easier.
-
Drainage and Ground Preparation: Ensure the area has proper drainage to avoid pooling water. You may need to grade the space or install a gravel or concrete base for stability.
Define Your Cooking and Entertaining Needs
A successful outdoor kitchen meets your unique needs:
-
Cooking Preferences: Do you prefer grilling, smoking, or griddling? Will you install a pizza oven or a smoker? I hear the best things about the Ooni pizza oven, but as well began to layout the kitchen, we decided a grill, our Green Egg, a beverage fridge, and a griddle were the most important items for us.
-
Storage and Prep Space: Include cabinets or shelving for utensils, seasonings, and cookware. Ensure you have ample countertop space for food prep.
-
Entertaining Style: How often do you host gatherings? Plan for enough seating, serving areas, and perhaps even a bar for drinks.
Sketch a Layout
A simple sketch helps visualize your design. Include:
-
Zones: Cooking (grill, griddle, oven), prep (countertops), cleaning (sink), cold storage (fridge), and serving (bar or table).
-
Workflow: Arrange the zones to mimic an indoor kitchen’s efficiency—placing the fridge near prep space and the grill close to the serving area.
-
Clearances: Leave enough space around appliances for safety and comfort. Plan at least 3 feet between cooking and seating areas.
Budget Wisely
While DIY saves on labor, materials and appliances add up. Your budget should include:
-
Materials: Frame structure, countertops, cladding, fasteners, sealants.
-
Appliances: Grill, fridge, sink, griddle, lighting.
-
Tools: Saws, drills, trowels, polishers, safety gear.
-
Contingency: 10-20% extra for unexpected costs.
A realistic budget guides your material choices, including the cladding–up next!
Choosing Your Cladding: Weighing Options for Style, Durability, and Cost
Cladding is the outer layer that defines your kitchen’s look and protects its structure. The right choice balances style, durability, cost, and maintenance. Let’s dive into popular options:
Plaster (Cement Plaster or Stucco)
Plaster offers a sleek, contemporary finish with versatile color and texture options. It’s applied in multiple coats over a wire mesh or cement board substrate, creating a smooth or textured surface.

Take time to weigh your budget, style preferences, and DIY skill level. Whether you opt for plaster’s smooth finish, the earthy richness of stone, the classic appeal of brick, or the versatility of tile, your chosen cladding will shape the heart of your backyard culinary haven.
DIY Outdoor Kitchen: Building a Strong, Durable Frame
Introduction to Frame Building
The frame is the backbone of your outdoor kitchen. It supports everything from polished concrete countertops to appliances, cladding, and decorative finishes. A poorly constructed frame can result in sagging counters, cracked cladding, or even safety hazards. Conversely, a well-built frame ensures stability, longevity, and a professional finish.
In this section, we’ll walk you through step-by-step instructions to build a robust frame, discuss materials (including wood and concrete block options), and integrate appliance spaces like the Weber griddle and outdoor fridge. By the end, you’ll have a clear roadmap to constructing a solid base for your entire kitchen.
Choosing the Right Frame Material
There are two primary materials for building an outdoor kitchen frame: concrete blocks (CMU) and pressure-treated lumber with cement board sheathing. Both have their pros and cons.
Concrete Block (CMU) Frames
Concrete Masonry Units (CMUs) are durable, non-combustible, and highly weather-resistant.
Advantages:
-
Fireproof and resistant to moisture and pests
-
Provides solid weight-bearing support for heavy countertops and appliances
-
Long-lasting with minimal maintenance
Disadvantages:
-
Requires masonry tools and skills
-
Heavier and harder to modify after construction
-
Typically more time-consuming to build

Pressure-Treated Wood Frames with Cement Board
Pressure-treated lumber (rated for ground contact) forms the skeleton, which is then covered with cement board for fire resistance and durability.
Advantages:
-
Easier to cut and assemble with standard carpentry tools
-
Lighter and faster to build than concrete block
-
More adaptable for custom designs and last-minute changes
Disadvantages:
-
Requires cement board sheathing for fire protection
-
More vulnerable to moisture and pests without proper sealing
-
Needs careful bracing to handle heavy countertops

Tools and Materials for Frame Construction
Materials:
-
Pressure-treated 2x4s or 2x6s (or CMUs if using blocks)
-
Cement backer board (e.g., HardieBacker)
-
Galvanized screws and brackets
-
Concrete mix (for footings or pads, if needed)
-
Metal lath for plaster cladding (if applicable)
Tools:
-
Tape measure and level
-
Circular saw or masonry saw
-
Drill/driver with masonry bits (for blocks)
-
Hammer and nails (if using wood)
-
Safety gear: gloves, goggles, dust mask
Preparing the Site
Before building, prepare the foundation:
-
Clear the Area: Remove grass, roots, and debris. Level the site.
-
Lay a Base: For CMU frames, pour a concrete footing. For wood frames, use concrete pavers or treated posts on compacted gravel for stability.
-
Drainage: Ensure the ground slopes slightly away from the kitchen to prevent water pooling.
Step-by-Step Frame Construction
Layout and Marking
- Mark the perimeter of the kitchen layout using stakes and string lines.
- Double-check measurements for appliance placement (grill, griddle, fridge) and counter heights. Standard countertop height is ~36 inches.
Building with Concrete Blocks (if chosen)
- Lay the first row of blocks on a concrete footing, ensuring level placement.
- Stagger joints in subsequent rows for strength. Use masonry adhesive or mortar to bond blocks.
- Leave gaps for appliances: frame openings for the fridge and griddle, ensuring proper dimensions.
- Fill block cores with concrete and rebar if extra strength is needed.
Building with Pressure-Treated Lumber
- Cut 2x4s to size for horizontal and vertical framing.
- Assemble the base frame, securing corners with galvanized screws and corner brackets.
- Add vertical supports every 16–24 inches. Include extra bracing at appliance cutouts.
- Attach horizontal supports at the top and bottom of openings.
- Cover the entire frame with cement board, securing with corrosion-resistant screws.
Integrating Appliances into the Frame
Weber Griddle
-
Dimensions: Check your specific griddle model (e.g., Weber 36″ or 28″).
-
Frame Support: Add extra horizontal supports to bear the weight. Consider using angle brackets for reinforcement.
-
Ventilation: Leave clearance underneath and behind for airflow.
-
Gas Line Access: Plan a pathway for safe, concealed gas connections.
Outdoor Fridge
-
Placement: Frame an opening large enough for the fridge’s dimensions plus 1–2 inches of ventilation space.
-
Base Platform: Create a solid, level surface using treated plywood or a concrete slab.
-
Power Access: Leave space for electrical wiring and outlets. Use GFCI-protected circuits.
Key Considerations for Frame Strength and Longevity
-
Level and Square: Use a spirit level to check horizontals and verticals at each stage. Uneven frames lead to countertop and appliance issues.
-
Bracing: Add diagonal braces for stability, especially for wood frames.
-
Fasteners: Use corrosion-resistant screws and brackets to withstand outdoor conditions.
-
Fireproofing: Cover wood frames entirely with cement board. For CMU frames, ensure proper sealing of joints.
-
Weatherproofing: Seal all wood surfaces and apply flashing or waterproof barriers where necessary.
Preparing for Cladding and Countertops
Before applying cladding or installing countertops:
-
Clean Surfaces: Remove dust and debris from the frame.
-
Attach Metal Lath: If using plaster cladding, secure lath over cement board for a solid base.
-
Plan Cutouts: Mark and cut spaces for the griddle, fridge, sink, and gas/electrical lines.
-
Support Countertops: Ensure the frame can bear the weight of polished concrete or other heavy materials. Add extra supports under large spans.
Optional Enhancements
-
Add a Bar Overhang: Extend part of the countertop beyond the frame to create a casual bar seating area.
-
Incorporate Shelving or Cabinets: Frame in additional storage for utensils, cookware, or cleaning supplies.
-
Integrate Lighting: Pre-run conduit or low-voltage wiring for under-counter or accent lighting.
Your Frame, Your Foundation
Building a solid frame is the most important step in your DIY outdoor kitchen. Whether you opt for a concrete block or wood frame with cement board, meticulous planning and execution will ensure your kitchen stands strong for years to come. Pay attention to appliance integration, use weatherproof and fire-resistant materials, and don’t rush the process—this foundation supports every element to follow, from polished concrete countertops to sleek plaster finishes.
