The commercial real estate market emerged in France in the 1970s to respond to the growth in the number of office jobs in the industrial and tertiary sector. The french government plays an important role in the building of a commercial real estate portfolio with the creation of the DATAR (Interministerial delegation for regional planning and regional attractiveness) in 1963 and the implementation of its policy metropolises of balance which promotes the construction of business centers in Lyon and Bordeaux [1] . The development of a commercial real estate market allows the growth of new professions dedicated to the management and fitting out of offices. This professional space will mainly open up to the trades of urban design from the years 1980-1990, where the white buildings will give way to the construction of office buildings taking into account the demand for project management [2 ] . We then see architects, urban planners and building engineers positioning themselves in the sector by offering project management assistance services (AMO) or general contracting [3] .
The office Design & Build market is not a professional sector with well-defined borders, it is a competitive space where different professional groups seek to appropriate the monopoly of certain activities [4] or at least to be recognized as a greater legitimacy in their exercise.
