  "summary": "Joists, decking boards, footings, fasteners, and cost for a 10x14 deck.",
  "description": "A 10 by 14 foot deck is a comfortable dining-and-grill platform at 140 square feet, and its material list is entirely determined by three numbers: joist spacing, board width, and the direction you run the decking. This calculator counts joists at 12 or 16 inch centers, computes linear feet of decking with a waste allowance for cuts, sizes the beam and footing count, and prices the whole thing at your material rate — pressure-treated pine, cedar, or composite. Composite roughly doubles the deck-board line but eliminates staining, which is the trade most homeowners are actually deciding between.",
  "formula": "Joists = (Width ÷ Spacing) + 1. Decking LF = Area ÷ (Board Width ÷ 12) × (1 + Waste%). Cost = Framing + Decking + Hardware + Footings.",

    {
      "q": "How many joists does a 10x14 deck need?",
      "a": "Running joists across the 10-foot span at 16 inch centers, you need about 11 joists plus rim boards. Composite decking usually calls for 12 inch centers, which pushes it to 15."
    },
    {
      "q": "Do I need a permit for a 10x14 deck?",
      "a": "Most jurisdictions require a permit for any deck attached to the house or more than about 30 inches above grade. Freestanding low platforms are sometimes exempt — check locally before building."
    },
    {
      "q": "Composite or pressure-treated?",
      "a": "Composite costs roughly two to three times more up front for boards but skips annual staining. Over a 20-year horizon the totals converge; the real decision is whether you want the maintenance."
