Portland architecture includes a number of notable buildings, a wide range of styles, and a few notable pioneering architects.

The scale of many projects is relatively small, as a result of the relatively small size of downtown-Portland blocks (200 feet by 200 feet) and strict height restrictions enacted to protect views of nearby Mount Hood from Portland's West Hills. Although these restrictions limit project size, they contribute to Portland's reputation for thoughtful urban planning and livability.

Many older buildings have been preserved and re-used, including many glazed terra-cotta buildings.

Portland is a leader in sustainable architecture and is known for its focus on urban planning. As of 2009, Portland has the second highest number of LEED-accredited "green" buildings of any city in the U.S., second only to Chicago.^[1]
