The Tree Houses for Swamp Dwellers sculpture is now located beside the Avon River on Colombo Street (Town Hall end). The artwork is by Christchurch artist Julia Morison.

According to this Press article:

The sculpture was inspired by Canterbury’s history. The 10 “treehouses” are shaped like kahikatea trees, which were once common in the area. The name of the artwork was inspired by a Christchurch colleague of Morison, who jokingly referred to Cantabrians as “swamp dwellers”.
