(b Ibadan, 10 Sept 1951). Nigerian architect. He was one of the 17 foundation students admitted to the two-tier architecture degree programme of the new School of Environmental Design at the University of Lagos in 1971 under John S. Myers and David Aradeon. After graduating with the BES (pre-architecture, 1974) and MED (architecture) degree in 1977, he served four years of apprenticeship in the Ilorin architectural offices of Niger Consultants. In the period 1981–5, he served as the Project Manager of the Economic and Technical Services Limited on the Agbara Estate project, the residential and industrial estate on the Badagry Expressway. Since 1985, when he opened his architectural office, the Siji Dosekun Partnership has been responsible for various projects. In Grailland, the sanctuary for the Grail followers in the Iju Hills (1985), his use of red bricks on the Gate House and fence walls, in conjunction with the green foliage and tall trees on the undulating landscape, achieves a spiritually uplifting ambience at the entry gates. Dosekun was a leading member of the generation of young Nigerians educated completely within the country in the 1970s, and his houses and residential projects continually question the basic assumptions expressed in Nigerian domestic architecture of the 1950s–1970s. By completely separating the dining- from the living-room in the four-storey apartment building constructed for the Integrated Capital Service Ltd in south-west Ikoyí (1992), Dosekun’s design enshrines the privacy of the family during meals. It also restores a measure of family control over its entertainment budget in a culture noted for its open-house hospitality. With the reintroduction of the fanlight and the consequent high ceilings (an idiom of the architectural language of early 20th-century Lagos), his design allowed air to circulate through the staggered corridor into the sleeping spaces in the east and west wings.
