Rotten: 81. 1  Critics Consensus: Exuberant and eye-popping, Avengers: Age of Ultron serves as an overstuffed but mostly satisfying sequel, reuniting its predecessor's unwieldy cast with a few new additions and a worthy foe.
Decks are less expensive than most other home additions. And because decks are so popular, they also make homes more marketable and valuable. Here's a look at what they cost. For basic designs using the least expensive lumber, you can expect to pay from about $6 to $8 per square foot of deck area. Even if you choose top-of-the-line redwood lumber or want a hot tub, material costs are still reasonable, anywhere from $20 to $35 per square foot.
Most contractors price their decks per square foot. Our average deck is around 400 square feet or 20' wide by 20' long. Most houses are better suited for a more rectangular shaped deck, say like a 14' by 28'. Knowing that decks are usually priced per square foot can help you better speak the language of deck builders.
