Space-saving furniture folds down from the wall when needed to maximise the use of space in a minimal set-up. Birch plywood doors can be used to hide the kitchenette from view.

"The purpose of Majamaja is to show how small-scale architecture, combined with green technology, can compensate for big volumes and centralised on-grid systems," said Pekka Littow.

"Majamaja offers dwellers an opportunity to disconnect from daily routine...
