Georges-Eugène Haussmann
The Trust engaged the services of Georges-Eugène Haussmann, the town planner who had successfully restructured the city of Paris. Haussmann believed in Euclidean layouts, comprising straight avenues intersecting each other at right angles. This necessitated ploughing through already built-up areas. His other favoured concepts included 'circulation' (i.e. constructing roads for the movement of people and goods) and 'respiration' (leaving open spaces for the city to breathe).
