Rosemary Stjernstedt, who has died at the age of 86, was the first woman architect to reach Grade I at the London County Council, writes Diana Rowntree. As one of the five group leaders, she led the team that made a success of Alton East in Roehampton.
After working during the Second World War in the Stockholm planning department, with occasional commissions from Ralph Erskine, Stjernstedt went to the lcc and later worked for the London Borough of Lambeth ,where she was responsible for schemes including Central Hill. Her final move was to the Ministry of Housing and Local Government.
The fact that Stjernstedt was a born leader, decisive yet popular, and her post-war dedication to the community, obscured her excellence, sensitivity and resourcefulness as an architect.
She is survived by her son Robert and her partner, Fred Parker.
