If you have narrowed your shortlist to two specific designs, this is exactly the kind of decision where a side-by-side spec view saves a weekend of second-guessing. Both plans below are complete, code-aware DIY builds, but they differ on the things that matter for a backyard project — total cost, raw labor hours, footprint, and the wood species on the cut list.

Cost & budget
The 10x12 ft Grill Shelter Lean-To Shelter Plan lands in the $1,800–$2,825 range for materials in Pressure-Treated Pine, while the 10x12 ft Patio Lean-To Lean-To Shelter Plan runs $1,800–$2,825 in Pressure-Treated Pine. The second plan is approximately 0% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Pressure-Treated Pine over Pressure-Treated Pine and the difference in cubic concrete volume between 2 and 2 footings.
Labor & difficulty
At ~16 hours, the 10x12 ft Grill Shelter Lean-To Shelter Plan is rated Beginner. The 10x12 ft Patio Lean-To Lean-To Shelter Plan takes ~32 hours and is rated Intermediate. The labor delta is roughly 16 hours, or one extra working day on the 10x12 ft Patio Lean-To Lean-To Shelter Plan. If you are newer to outdoor woodworking, the 10x12 ft Grill Shelter Lean-To Shelter Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 120 sq ft vs 120 sq ft, you are choosing between a generous patio cover and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 10x12 ft Grill Shelter Lean-To Shelter Plan needs a clear area of approximately 14×16 ft and the 10x12 ft Patio Lean-To Lean-To Shelter Plan needs 14×16 ft.
Material & durability
The 10x12 ft Grill Shelter Lean-To Shelter Plan is built from Pressure-Treated Pine, while the 10x12 ft Patio Lean-To Lean-To Shelter Plan calls for Pressure-Treated Pine. Both plans share the same species, so you can buy from a single lumber order if you build them in sequence — a common move for homeowners adding both a primary structure and a complementary screen or arbor.
Verdict
For a builder weighing these two specifically, 10x12 ft Grill Shelter Lean-To Shelter Plan is the faster build. If both fit your budget and yard, default to the design whose style language matches the rest of your house — a Craftsman bungalow looks awkward beside a modern slatted pergola, and vice versa.
