Born on 16 August 1888 in Salt Lake City, Utah, United States, Robertson was the younger son of Casper Ludovic van Uytrecht Robertson, originally from Liverpool, by his marriage to Ellen Duncan, of Ohio. He spent his early childhood in the United States and was sent to England in the 1890s to be educated at Eastfield House, Ditchling, Sussex, and at Malvern College. Robertson then trained at the Architectural Association School of Architecture in London, from which he graduated in 1907, and also in France. In 1913, he received a diploma in architecture from the École des Beaux-Arts in Paris. Between 1913 and 1914, he gained experience in the offices of architects in London, Boston, and New York City, and worked on a project at Le Touquet in northern France.
On his return to civilian life in 1919, Robertson formed the firm of Easton & Robertson with John Murray Easton. Their offices were at 168 Regent Street, London, and they continued the partnership until 1931. In 1920 he began to teach at the AA School of Architecture in London, where he became a friend of the School's secretary, F. R. Yerbury. They later travelled together in Europe. Robertson was appointed as Principal of the School in 1926 and from 1929 to 1935 was its Director of Education. He became a member of the Congrès International d'Architecture Moderne, but left it when he began to find it too narrowly focussed.
Robertson designed the British Pavilion for the 1925 International Exposition of Modern Industrial and Decorative Arts in Paris, the event which created the term Art Deco. His Permanent Exhibition Hall for the Royal Horticultural Society was awarded the RIBABronze Medal in 1928. His Schloss Freudenberg, at Rotkreuz in Switzerland, is a country house built for Erwin Hürlimann, chairman of Swiss Reinsurance, between 1929 and 1933. His other notable buildings include the Metropolitan Water Board Laboratories, London, in which he paid tribute to the work of Erich Mendelsohn, the Bank of England Printing Works at Loughton in Essex, and the Faculty of Letters building at the University of Reading. His twenty-six-storey Shell Centre, in York Road, Waterloo, London, was so high that it caused planning arguments, while its Art Deco style was unwelcome to other architects, who considered it out of keeping with the Modernism of other large new buildings in the neighbourhood. 'Sentosa', Esher, another domestic building designed by Robertson, built for the Erhardt family in 1934, was made a listed building in 1985.
