Re­mo­val to Swe­den 1939. Study at the re­gent Street Po­ly­tech­nic in Lon­don 1932-37. Since 1936 own architect's of­fice in Swe­den. Gast­pro­fes­sur at the ETH Zu­rich (1964-65) and to the McGill Uni­ver­sity, Mon­treal (1967-68). To­ge­ther with its part­ner Aage Rosenvold sket­ched more than 80 pro­jects (hou­ses, fac­to­ries, plan­ning of urban districts) to Er­s­kine, about which the hou­sing es­tate in Byker, New­castle, Eng­land (1969-80) cla­ri­fies the prin­ciple of its con­sciously hu­ma­nen work best: the close con­tact to the later in­ha­bi­tants of its buil­dings, the con­side­ra­tion of in­di­vi­dual de­si­res, me­cha­nisms for han­di­cap­ped ones as well as an eco­no­mic and energy-conscious buil­ding me­thod. To em­pha­size are also its va­ria­tion wealth as well as its so­lu­ti­ons for ex­treme cli­mate con­di­ti­ons.
