We made Kunsthalle portal in the course of a redesign.
The greatest challenge was the event calendar. The event calendar serves not only for program information, but as exhibition archive too. The calendar has two views and three time interval modes. The yearly view was required by the archive function.
The opening page of the portal was constructed from boxes which can be resized and replaced by the editors of the site. Experience shows that over long periods of time, dynamic layouts are the most usable structure for index pages.
