Key Considerations When Designing a 12x18 Deck Layout
At 216 square feet, this layout centers the beam across three matching bays instead of running it as one long span, which keeps the load evenly distributed across the depth. ArcSite lets you move that beam or rim joist callout if your own house tie-in doesn't land where the default plan expects it.
