Allied Works Architecture (AWA) has unveiled designs for a $50 million expansion to the 91-year-old soccer stadium in Portland, Oregon’s Providence Park, home to the Portland Timbers and Portland Thorns soccer teams.

The stadium expansion, according to information on the AWA website, is conceptually inspired by William Shakespeare’s Globe Theatre in London and will aim to add roughly 4,000 seats to the existing stadium complex. The new scheme represents the stadium’s second expansion since 2011 and will consist of raked stadium seating stands topped by an open steel truss canopy along the existing stadium’s eastern side.

The new expansion will also create a street-level public arcade area that will contain pedestrian-oriented spaces to be used before and after games. The expansion would boost the stadium’s capacity to 25,000 seats, a relief for some of the 13,000 fans currently on a waiting list for season tickets at the stadium. The team, according to Oregon’s Business Tribune, has sold out every Major League Soccer regular season and playoff game at the stadium.

The arcade structure will serve to complete the park’s original master plan, first proposed by the office of A.E Doyle and Morris Whitehouse in 1926. That original scheme proposed a substantial arcade structure; AWA’s design takes a more contemporary approach and is made up of more open steel trusses.

The stadium expansion comes after the recent completion of AWA’s designs for a training facility for the Timbers team in Beaverton, Oregon. That 6,000-square-foot project was built by Turner Construction and opened in 2016.

Construction on the stadium expansion is due to begin this fall and is expected to be completed for either the 2019 or 2020 MLS season. The developer is Peregrine Sports LLC.
