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.
They can cost anywhere between $3,900 and $4,500 for a 12-by-18 deck, though you can get individual deck boards for $20 to $50 per square foot. Composite decks may cost less initially, but they have a lot of maintenance over the lifetime of the deck, especially if you install pressure-treated lumber.
