Budgeting for a deck
The cost of a professionally built pressured-treated wood deck starts at about $15 per square foot, including materials. The cost for an elaborately built deck using costly hardwoods or composite materials can run about $35 per square foot. As with any remodeling or building project, it's best to get several estimates and to discuss your ideas with an architect or designer — or several — so you can get a range of prices and find one that suits what you can afford.
Take into consideration what your house is worth and how long you plan to live in it. You don't want to overspend on an oversize deck that does not suit the scale of your home nor do you want to skimp on the size of the deck if you have a large home. If you plan to sell your home shortly after the deck is complete, you might not want a deck that costs too much and that you will not get to enjoy for long.
Generally, gathering three good estimates may be enough; pick the one in the middle. Be open and honest with your designer. He or she may be able to suggest ways to save you money but still get the deck you want.
Value for Your Money A new deck can expand the outdoor living space to your home and can also increase your home's value. Decks are consistently one of the improvements you can add to your home that will increase its value
Even in a down housing market, a deck upgrade can mean more money in your pocket when you sell your home
