Spatialist Studio was founded in 2023 by Iiris Tähti Toom, Sebastian Fischer Stripp, and Henri Kopra as an architectural practice focused on collaboration with public authorities, universities, and local NGOs to produce high quality public space and building. The studio's method of work oscillates between design and research to constantly question the role of the architect for best environmental and social practice.

Iiris and Henri studied architecture in the universities of Bath and Nottingham respectively before reading MPhil in Architecture and Urban Design at the university of Cambridge. After a BSc Architecture at Bath, Sebastian acquired an MSc in Building Technology from TU Delft. While the studio's work widely focuses on the public domain, Iiris's personal typological interest lies with saunas and collective bathing, Henri's in social housing, and Sebastian’s in architectural applications of machine learning, following their academic diploma projects.
