(b Helsinki, 29 Sep 1932). Finnish architect. He graduated from the Helsinki University of Technology in 1960, first working as an assistant architect in the office of Alvar Aalto and then directing his own practice from 1961. He was Head of the Exhibitions Office of the Museum of Finnish Architecture, Helsinki, in 1965–7 and later became State Artist Professor of Finland (1988–93). Gullichsen was a leading innovator in modern Finnish architecture; his style of design represents an assimilation of a broad variety of 20th-century sources, implemented with sensitivity to local requirements and with typical Nordic restraint. His mentors included, in addition to Aalto, such major mid-century Finnish architects and theorists as Aulis Blomstedt and Reima Pietilä. Noted projects by Gullichsen include the Suutarila housing complex (1977; with Timo Vormala), which was commissioned by the City of Helsinki Housing Production Office; and the Parish Centre (1983), Kauniamen, which emphasized his preference for an architecture of walls; the building was placed on stepped levels with subtle curved forms, discreet openings and light inlets which ingeniously balanced aspects of austerity and radiance. His interest in modular, prefabricated structures can be seen in ‘Moduli’ (1974; with Judani Palaasma), a system for low-cost standardized holiday homes designed around an open-plan living area of 15 cubes, which allow interchangeable use. This design typified his aptitude for thoughtful, compact and integrated schemes to withstand the variations of the Finnish climate.
