The competition entry for the Guggenheim Museum in Helsinki envisions modular building volumes that adjust to environmental conditions. The ample spaces in the base are framed within a simple structural design that provides optimal areas for showcasing the museum’s permanent and temporary exhibitions. While following the site’s angular layout, the top volume moves according to the changes in sunlight and snowfall. In summer, the two volumes unite in a simple rectangular mass, while in winter, the top volume cantilevers above the entrance area, creating a luminous environment protected against snow where visitors can meet and enjoy views to the sea.
