Elevate your outdoor living (literally).
If you have a sloping yard or a second-story door, a deck might be your best option for outdoor living. Chapter 6 covers the design and construction of wood and composite decks, as well as screened porches and three-season rooms.
The chapter starts with a critical decision: wood vs. composite. Pressure-treated pine is affordable but requires staining every two years. Cedar and redwood are naturally rot-resistant but cost more. Composite decking (like Trex) never needs staining, but it gets hot in direct sun and can sag if spaced improperly. The authors recommend wood for traditionalists and composite for low-maintenance enthusiasts.
Deck framing is where beginners make mistakes. Joists (the horizontal supports) should be spaced 16 inches apart for standard decking. Beams (the larger supports under joists) should be doubled up for spans over 8 feet. The book includes span tables so you can calculate the correct lumber size without overbuilding or risking collapse.
Footings are non-negotiable. In cold climates, deck posts must extend below the frost line (often 36 to 48 inches deep). In warm climates, a 12-inch-deep concrete pier is usually enough. The authors warn against setting posts directly in concrete—this traps moisture and rots the wood. Instead, use metal post bases that keep the wood slightly above the concrete.
Railings and stairs have their own requirements. Guardrails are required on any deck higher than 30 inches. Balusters must be spaced so a 4-inch sphere cannot pass through (a child-safety rule). Stair treads should be at least 11 inches deep, with risers no taller than 7 inches. The book provides step-by-step instructions for building a basic staircase.
Screened porches add complexity. You’ll need a roof, insect screening, and often a permit. The authors suggest starting with a simple open deck and adding a screen kit later, rather than tackling a screened porch as a first project.
Practical advice: Before building, call your local building department. Many decks require permits, and inspectors can flag unsafe construction. A $50 permit is cheap compared to rebuilding a collapsed deck.
