The main use of the deck, materials used and weight of items to go on the deck should all be considered when replacing a deck. This helps the homeowner select the right decking materials and design it for appropriate use.
If the deck is meant to be used mostly by the family for outdoor dining, the new deck should have sufficient space for a large table and chairs, as well as space around the table to walk comfortably. For more social situations, the new deck may need to be bigger or have additional seating. Some decks include built-in seating near the deck railing, which is something to be considered before construction begins.
The weight of what will go on the deck should also be considered. If a heavy hot tub is being placed on it, heavier decking materials should be used.
