Key Features
This 10x20 deck layout includes
- Framing plan with joist spacing and support placement
- Side step design
- Reinforced ledger board connection
- Mid-span bridging
- Adjustable handrail and step configuration
- Layout notes for railings, privacy screens, or pergolas
The steps run off the side rather than the end, worth switching in ArcSite if your yard's main access point faces the short end of the deck instead.
Key Considerations When Designing a 10x20 Deck
A deck this narrow and long benefits from side steps rather than steps centered on the short end, since a centered step would eat into one of the two zones on a 10-foot-wide surface. In ArcSite, you can adjust this 10x20 deck layout's step placement and railing detail to fit your own access point.
