  1. ACADEMIC VIEWS ON THE ECONOMICS OF CONSTRUCTIONFRENCH VARIATIONS (1920/1970) 1) Public housing of the 1920’s in France. Short presentation of early built garden cities in the outskirts of Paris : - Les Lilas (1921-1923 and 1930-1931) - Stains (1921-1933)

  2. LES LILAS • Developer : Office public d’HBM du département de la Seine • Architects : Pelletier (Paul), Teisseire (Arthur) • Ground area : 6 hectares • Programme and dates of construction (two phases) : 1921-1923 : 212 dwellings, in one- and two-family houses, (destroyed 1971-1973, and replaced by housing blocks) 1930-1931 : addition of approx. 100 dwellings in housing blocks (northern part of the ground area, still existing)

  13. STAINS • Developer: Office public d’HBM du département de la Seine • Architects : Gonnot (Eugène), Albenque (Georges) • Ground area : 28 hectares • Programme : 1700 dwellings, of which 460 one-family houses and 300 rooms for bachelors • Dates of construction : 1921-1933 At the period it was built, the garden city accomodatedone third of the population of the municipality. It still represents 15% of the dwellings in this municipality where social housing in a whole accounts for 69% of housing.

  21. ACADEMIC VIEWS ON THE ECONOMICS OF CONSTRUCTIONFRENCH VARIATIONS (1920/1970) 2) Construction costs : academic approach of the comparison between single-family houses and housing blocks. - The thesis by Henri Sellier (1921) - The thesis by Claude Olchanski (1945) and what follows until the 1960’s

  22. The thesis by Henri Sellier (1921) • A view based on a public developer experience. • At given volume and finishes, single family houses are cheaper than apartments in block houses (even including cost of public networks). • Therefore, construction in the suburbs has to favour a city of houses project. • Architecture and composition : reference to Raymond Unwin and the principles of garden cities.

  23. The thesis by Claude Olchanski (1945) • Economic denunciationof garden cities, « particularly expensive given the extensions of roadways, pipework, the large number of foundations, structural works and roofs ». • Therefore, construction has everywhere to favour housing blocks, whose « reduced cost [permits] to improve comfort ». • As for the cost of construction itself, assertion is only based on arithmetic evidence, without any reference whatsoever to observations : a very questionable approach. • As for the cost of public networks, another arithmetic evidence, that will become recurrent… but is equally questionable.

  25. And later ?Academic views of the 1950’S and 1960’s • The Faculty of Law and Economics continued to crown doctoral works without these being based on facts. • The source of such an attitude is not to be found in the sphere of economic thinking. • References cited by economic authors prove that they matured their views under the influence of an understanding of modernity propagated by architects and town-planners. • The kind of profession of faith that held sway hereafter perfectly reflected professional interests of specialists involved in construction.

  26. Conclusion • Two opposite views : the first favouring the city of houses project, the latter favouring housing blocks. • The lack of factual bases did not prevent the latter from contributing to real effects… • …but it resulted in a gap between construction culture sought by the elites and the popular perception of the problem. • Similar gaps would undoubtedly happen if, for whatever reason, we once again cultivated views of project economics subject to a doctrine rather than to observations.
