Sustainable Development Partners has completed its agreement to buy Westport High School, 315 E. 39th St., from Kansas City Public Schools.
Terms of the sale were not disclosed when it was announced Friday.
The buyers previously purchased Westport Middle School at 300 E. 39th St., and the two properties will become a multiuse redevelopment known as Westport Commons.
Redevelopment already is underway at Westport Middle School, purchased in January 2014. The partners are working with Plexpod Westport Commons to develop a collaborative office space, known as co-working. Completion on the former middle school is set for 2017.
Development plans for Westport High remain in progress. The ownership group said it would work with the community to complete a site plan.
The partners previously worked with Dalmark Development Group and Straub Construction to redevelop Swinney Elementary School at 47th and Jarboe streets into 71 apartment units named West Hill. Those apartments are 100 percent leased.
The district continues to seek buyers for other schools no longer in use.
