From the judges' report:
De boomhut is a wise, clear, even poetic, example of how an established topos of the collective imagination may be revisited with a fresh eye to reveal a continued relevance to modern times. Marije Tolman and Ronald Tolman return to the “house in the trees”. Their house, however, is rich with subtle cultural references ranging from symbolist painting to the most refined 20th century graphic art.
