Deck Cost in Central Oregon by Size
A new deck in Central Oregon costs about 30 to 60 dollars per square foot installed, so a 14 by 20 foot deck runs roughly 8,400 to 16,800 dollars and a 20 by 20 foot deck about 12,000 to 24,000 dollars. Composite decking costs more upfront than wood but holds up far better to Bend's intense sun, snow, and freeze and thaw.

Wood or composite in the high desert
Central Oregon sun is brutal on decks. Intense UV at elevation dries and greys wood fast, and snow and freeze and thaw work at the boards all winter. Pressure treated wood costs less upfront but needs regular sealing and replacement of split boards. Composite costs more but resists fading, splintering, and moisture, which makes it a popular choice for Bend decks that see heavy sun and snow.
What affects the price
Height off the ground, railings, stairs, and built in features like benches or lighting all add to the cost, as does the footing work needed for frost depth in Central Oregon. A ground level platform deck is far cheaper than an elevated deck with stairs and railings.
