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 8x6 ft Horizontal Slat Privacy Screen Trellis Plan lands in the $650–$1,025 range for materials in Redwood, while the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan runs $575–$900 in Black Locust. The second plan is approximately 14% more expensive at typical 2026 lumber-yard pricing — driven mostly by the choice of Redwood over Black Locust and the difference in cubic concrete volume between 3 and 3 footings.
Labor & difficulty
At ~121 hours, the 8x6 ft Horizontal Slat Privacy Screen Trellis Plan is rated Advanced. The 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan takes ~14 hours and is rated Beginner. The labor delta is roughly 107 hours, or one extra working day on the 8x6 ft Horizontal Slat Privacy Screen Trellis Plan. If you are newer to outdoor woodworking, the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan is the safer pick — it uses simpler joinery and fewer compound cuts.
Footprint & site fit
At 48 sq ft vs 36 sq ft, you are choosing between a focal-point garden structure and a focal-point garden structure. Allow at least 24 inches of clearance on every side for furniture and walking paths — that means the 8x6 ft Horizontal Slat Privacy Screen Trellis Plan needs a clear area of approximately 12×10 ft and the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan needs 10×10 ft.
Material & durability
The 8x6 ft Horizontal Slat Privacy Screen Trellis Plan is built from Redwood, while the 6x6 ft Modern Black-Frame Privacy Screen Trellis Plan calls for Black Locust. 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, 6x6 ft Modern Black-Frame Privacy Screen Trellis 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.
