Apart from le Corbusier, whose book Towards a New Architecture, he read and whose early work he visited there were other important influences on the young Lasdun.
He attended the Architectural Association school, and for a measured drawings exercise chose the Orangery in Kensington Gardens, which started a growing interest in the work of Nicholas Hawksmoor. He left the AA to work for Wells Coates, attracted by his Lawn Road flats, not just for their form, which prefigure his own later strata, but by their socialist programme.
E.A.A. Rowse, principal at the AA taught "the idea that architecture was not about style so much as about social needs; that it was above all a social art." And the ideas of Rowland Pierce, one of his tutors, on Beaux Arts planning, particularly the importance of processional circulation appealed to Lasdun, and he studied this in the work of Lutyens.
In 1938 Lasdun moved jobs to work for Lubetkin, founder of Tecton, where he found "a classical attention to detail and a continuity of attitude to concrete which had its roots in the work of Auguste Perret."
