Deck Addition

Home Deck & Patio Addition

Add a 16-by-20-foot deck using pressure-treated joists supported by 4×4 posts anchored to concrete piers. Install composite deck material in a simple linear pattern. Include a built-in bench and planter of the same decking material. Include stairs, assuming three steps to grade. Provide a complete railing using a matching system made of the same composite as the decking material.

These are the primary parts of a deck you should know:

• Footing: made of concrete, underground components support deck posts.
• Joists: makes deck’s horizontal frame.
• Piers: ground, concrete support posts.
• Ledger: support one side of the deck.
• Flashing: prevents water from entering the space where your deck connects to your home.
• Decking: boards used to form the floor of the deck.
