This workshop provides a list of tools, materials and step-by-step instructions for designing and building a basic deck. Additional information on specialty deck design and construction for multilevel decks, reinforced decks for hot tubs, and other special feature elements is built in to Build a Deck. Choose the right lumber and calculate how much wood is needed. Multiply the length x width of the deck, taking into account stairways and railings to come up with how much decking material to order. To figure out how much material will be needed for the structural elements, it's best to seek professional advice from the home center regarding what size boards and posts for your deck plans. Then add 10 percent to the final figure for waste. Before you start the deck, it's important to install some flashing to protect the siding of your house. Be sure to wear a pair of heavy gloves when working with flashing, which is heavy. The flashing has to be cut to fit under the doorframes, so be sure to measure the width of the door to know how much flashing to cut. The best way to work with flashing is to use tin snips or score it, then cut it off. You may have to remove nails to be able to slide the flashing under the siding.
Be sure to check with a local engineer to check the different sizes and weights of footers for your particular deck. According to what you plan to have on the deck
