The purpose of this mission, "Assistance to project owners, contractors, architects, interior architects and/or decorators, designers", is to provide a graphic file to the consulted companies, specifying by drawing all the technical and aesthetic points for the costing of all the services necessary for the perfect completion of the project.


This mission must be based on the following essential elements:

  • A functional program to be submitted by the project owner or a professional programmer

  • A Concept drawn up by the designer and submitted in the form of drawings (3D, sketches, plans, elevations, etc.) as well as texts, videos and photo books, all of which are as explanatory as possible.

Before anything else, a preliminary meeting with the people involved in the project and a possible visit to the premises concerned (where they exist) are essential.

This should enable the scope of the project, its complexity and its context to be assessed.
