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 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) lands in the $1,350–$2,100 range for materials in Cypress, while the 10x12 ft Grill Shelter Lean-To Shelter Plan runs $1,800–$2,825 in Pressure-Treated Pine. The first plan is approximately 34% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Pressure-Treated Pine over Cypress and the difference in cubic concrete volume between 4 and 2 footings.
Labor & difficulty
At ~57 hours, the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) is rated Intermediate. The 10x12 ft Grill Shelter Lean-To Shelter Plan takes ~16 hours and is rated Beginner. The labor delta is roughly 41 hours, or one extra working day on the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress). 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 100 sq ft vs 120 sq ft, you are choosing between a focal-point garden structure and a generous patio cover. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) needs a clear area of approximately 14×14 ft and the 10x12 ft Grill Shelter Lean-To Shelter Plan needs 14×16 ft.
Material & durability
The 10x10 ft 3-Point Triangular Shade Sail Frame Plan (Cypress) is built from Cypress, while the 10x12 ft Grill Shelter Lean-To Shelter Plan calls for Pressure-Treated Pine. The species choice drives the cost delta and the maintenance schedule. Pressure-treated southern yellow pine is the cheapest and most rot-tolerant for in-ground posts; western red cedar is the DIY favorite for visible parts; redwood and white oak are heritage choices that command a premium.
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.
