Bettum’s design interests centre on spatial and aesthetic questions in architecture. Recent work in the studio has used Virtual Reality as a laboratory for spatial inquiries in relation to subjective experience, the construction of reality and the role of images in regimes of representation.

In 2014 he founded the SAC Journal which he edits and contributes to. The 2018 issue, Culinary Lessons, explored the space of food, and forthcoming issues include one on architecture and Virtual Reality.

Bettum’s earlier work includes pioneering novel design procedures with particle streaming as well as research on the use of fibres, textiles and composite material systems in architecture. He has practiced architecture in the design network, OCEAN (till 2000), and in his own office, ArchiGlobe. Bettum was a research fellow at the Oslo School of Architecture from 1997 to 2001 and headed a nationally funded research project on polymer composite materials in architecture.

Bettum has taught, lectured and been a critic at various schools in Europe and the USA, and his writing has been published in edited books and journals.
