Choosing the Right Grill Type
The first step in any DIY grill project is deciding what style of barbecue you want to build. There are several main options to consider:
Charcoal Grills
Charcoal grills are a classic choice that allows you to infuse real wood-fired flavor into your meats. They can be fashioned from a simple brazier design all the way up to complex offset smoker pits. You’ll need to factor in key elements like adjustable grates, ventilation, and sufficient insulation.
Pros
- Authentic charcoal and wood smoking flavor
- Inexpensive to construct
- Temperature control through adjustable vents
Cons
- Harder heat control than gas
- More cleanup from ash
Gas Grills
For convenient push-button cooking, propane and natural gas grills are hard to beat. You’ll need to incorporate burners, piping, and a drip pan in your design. Ventilation and safety precautions are especially critical.
Pros
- Easy push-button temperature control
- Heats up quickly
- Less cleanup than charcoal
Cons
- Requires installation of gas lines/tank
- Flavor not as robust as charcoal
Pellet Grills
Pellet grills combine the convenience of gas with the wood-smoke flavor of charcoal. Pellets are fed from a storage hopper into a burn pot. The electronic controls make it simple to dial in just the right temp.
Pros
- Digital temp control for precision
- Imbues food with smoky wood flavor
- Versatile grilling and smoking in one
Cons
- High initial cost to construct
- Reliant on electricity
Once you’ve settled on a fuel type, you can narrow down the exact grill design you want to DIY. Things like total cooking space, portability, and extra features will factor into your choice.
Designing Your Grill
You know what style BBQ you want…now it’s time to design it! Use these guidelines when drawing up plans for your DIY grill build:
Size
Consider how much total cooking space you’ll need. Allow room for at least 110-150 square inches per person so food has breathing room. Include additional space for warming racks and prep zones if desired.
Construction Materials
- Metal: Stainless steel and aluminum are durable, block wind, hold heat.
- Stone: Soapstone, brick, etc. retain heat well but heavy.
- Ceramics: Light yet fragile. Excellent heat retention.
- Common brick: Withstands up to 2000°F but can crack over time.
- Fire brick: Resists heat damage better than common brick.
Ventilation
Proper airflow is mandatory for temperature control, safety, and efficient fuel burning. Incorporate:
- Adjustable vents in grill lid and base
- Chimney vent for smoke evacuation
- Strategically placed air gaps
Extra Features
Customize your grill with built-in amenities:
- Side tables and shelves
- Tool hooks
- Warming racks
- Rotisserie
- Grill lights
- Pizza oven integration
- Storage cabinet
- Casters for mobility
Key Safety Tips
Like any home improvement project, safety should be your top priority. Follow these guidelines to keep things secure:
Fire Safety
- Surround grill with non-flammable materials
- Install smoke and CO detectors nearby
- Keep a fire extinguisher accessible
- Check for gas leaks on gas grills
General Safety
- Use protective equipment when cutting, drilling, etc.
- Make sure grill is stable and level
- Edge surfaces smoothly to prevent cuts
- Check local codes for any regulations
Food Safety
- Keep raw meats separated from cooked foods
- Use separate plates and utensils for raw and cooked items
- Cook meats to proper internal temperatures
- Keep perishable foods chilled before grilling
Constructing a Brick BBQ Grill
If you want a heavy-duty, durable grill that holds heat extremely well, brick is an excellent DIY option. Here is a step-by-step guide to constructing your own brick barbecue:
Planning
- Draw up plans with exact dimensions
- Purchase 12” x 12” fire bricks and high-temp mortar
- Have bricklaying tools ready (trowel, level, etc.)
Frame Construction
- Dig base 12” deep x 6” wider than grill on all sides
- Fill with sand and gravel for drainage
- Lay concrete foundation reinforced with rebar
- Build cinder block frame to desired dimensions
- Leave openings for ventilation and chimney
Installing Fire Bricks
- Lay courses of fire brick inside frame
- Use mortar to cement bricks together
- Build walls 4-6 bricks high
Grill Lid and Vents
- Form lid frame from steel stock
- Cut vent holes on top and bottom
- Attach adjustable steel vents over holes
- Attach handle and hinges
Grates
- Size grate bars to span width of grill
- Lay grate sections onto ledges in brick
- Install chimney starter on lowest course
Finishing Touches
- Apply high-temp sealant to interior
- Install thermometer through lid
- Cure grill by slowly increasing fire over time
- Add hooks, shelves, doors, etc. as desired
With good planning, high-quality materials, and proper safety measures, you can construct a DIY brick grill that will serve you well for years to come. The sense of satisfaction you’ll gain every time you barbecue on it makes all the hard work worth it.
