Silje Kolltveit and Anna Røtnes collaborate on landscape architecture and architecture through their respective practices, Studio Sted and Praksis A. Through projects for school libraries, school grounds and play areas, they have explored themes related to children and play. Loose natural materials and children’s ability to shape and transform places through participation are central to their design process.
They are both associate professors at the Oslo School of Architecture and Design (AHO), where they teach in the Landscape Architecture and Architecture programmes, respectively.

Studio Sted and Praksis A are contributing to OAT with "Naturbanken", installation and accompanying workshops for children and families on 20 and 27 September.
