Mafoombey
Martti Kalliala, Esa Ruskeepää,
with Martin Lukasczyk, 2005

Mafoombey was the winning entry in a design contestarranged by the University of Art and Design in Helsinki in 2005. The competition brief called for a space for listening and experiencing music within the set dimensions of two and a half cubic meters. The project was executed with 3D software and scale models. The design builds up from a simple architecturalconcept: a free-form cavernous space that is cut into a cubic volume of stacked material.

The low resolution of form and the perception of weight achieved through a layered structure were determined to be the key issues. Research into various materials suggested corrugated cardboard as optimal for its low cost and excellent acoustics. Furthermore, the material has a strong aesthetic appeal, which the designers felt had not been fully exploited at the scale of the project.

Mafoombey consists of 360 layers of seven millimeter corrugated cardboard, adding up to 720 half-square sheets. The sheets, 2.5 meters by 1.25 meters, are cut one by one using a computer- controlled cutter. The structure sits under its own dead weight without fixing. The lightweight assembly details ensure relatively easy transportation and quick construction.
