On his return to England from Sweden, de Maré joined the Architectural Press and became the acting editor of Architects' Journal, in 1943.

"[13] In that vein, in 1948, he started his documentation of the canals and waterways in which he explored the "vernacular (and) the anonymous architecture" which made up much of the landscape of the country.

As a result of his work on canals, he was commissioned in 1950 to travel throughout England to photograph early industrial sites and buildings by the then editor of the Architectural Review, A. R. Richards.

[16] The Functional Tradition within architecture had received little attention from contemporary architects until this study which promoted an increased interest in the qualities of early industrial structures.

De Maré's work in the 1960s reflected the other end of the industrial spectrum, focussing on modern power generation plants, to which his photographs frequently conferred a sculptural quality.

[21] A number of photographs attributed to de Maré appear in the Conway Library[22] at the Courtauld Institute of Arts, London.
