An outdoor kitchen is a small building that lives in the weather. Rain, freeze and thaw, and summer sun all work on it every day. What it costs depends far more on how it’s built than on how many burners it has.
The published numbers.
Lawn Love’s cost guide, updated October 2026, puts the national average at about $13,180, or roughly $495 per linear foot, with most projects between $5,060 and $17,280. Basic prefab builds start near $3,000; upscale kitchens run $40,000 or more.
For the stone or siding on the island itself, the same guide lists stucco at $5–$8 per square foot, brick veneer at $9–$15, manufactured stone at $15–$25, and natural stone at $20–$40.
Five things that move the price.
- The footing. A kitchen is heavy. It needs its own footing on solid ground below the frost line — not a patio slab that was poured for feet.
- The frame. Block or steel framing, built to carry stone and a heavy countertop without moving. Prefab frames cost less and give up some of that.
- The stone. Natural stone hand-set over the frame costs the most, and it’s the finish that looks better at year ten than at year one.
- The countertop. Thermal bluestone, granite or another dense stone, sized to overhang and pitched to shed water.
- Gas, power and water. Lines run by licensed trades, with sleeves set in the masonry before the stone goes on.
Questions to ask any builder.
- What does the kitchen sit on, and how deep is the footing?
- What is the frame made of?
- Is the stone natural or manufactured, and how is it attached?
- Who runs the gas and electric, and where are the sleeves?
- What’s the warranty, in writing?
