While taking charge on this part of the research with regards to Paris, the research employed three standard methods: 1) theory research about suburban planning, 2) research about local plan and 3) evaluation of the plans. For the part on Paris, the study focus on the architect for the City of Paris, Louis Bonnier, who was also the president of the Higher Commission of the City Planning established by Cornudet Law. The targeted communes of the suburban plan were 111 communes in Ile-de-France region (Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de- Marne, Val-d’Oise). Research materials were gathered from the Library of the Commission of the Old Paris (Commission du Vieux Paris :CVP) where Louis Bonnier established the unique list of monuments in Paris called Artistic and Archaeoligical Rack (Casier Artistique et Archeologique :CAA) in 1916 ; and in the Archive of Center of Architecture and Heritage (Cité de l’Architecture et du Patrimoine) in Paris.
