There are a variety of different reasons people build decks onto their homes or in other outdoor areas. One reason is to increase the resale value of the home. It is important to remember, if you are selling your home, your deck needs to look new. If it looks worn, in need of repairs or maintenance, it does not allow you to ask more for the property. Another reason people install decks is to have an area they are able to enjoy the outdoors, without having to worry about ground pests like ants. Because most decks are raised off the ground and use treated wood, like cedar lumber with insect protection, it keeps ants and other bugs from getting onto you deck.
People also build decks so they can incorporate different types of items into their design. For instance, you might want to add a fireplace or fire pit, outdoor kitchen, built-in grill, or a hot tub as part of your design. Just remember, the size of your deck depends upon what sort of items you want to include in your design. If you have many other items that will be placed outdoors on your deck, you need to make sure you allow for plenty of space. Also, do not forget to include furniture, such as chairs, tables, and benches, so you are able to have somewhere to sit and enjoy your deck after it is completed. Further, you need to account for the weight of these objects, and remember, you may need additional cedar lumber support posts and joists to support them.
