In charge, with Bernard Lamy, of the Faubourg de l'Arche development plan in the early 1990s, Roland Castro also received two commissions. Like most of his work, the Colisée building is above all an urban piece. It takes the form of a slightly deformed “U”, whose facades establish a continuum along the edge of the street. Inspired by the large buildings of the interwar period, Roland Castro built his edifice around a square, setting the tone for subsequent constructions in the neighborhood. The building is also adorned with light-toned stone to unify its five facades.

The Castro-Denissof agency was founded in 1988 by Roland Castro (1940) and Sophie Denissof (1955), later joined by Silvia Casi.

Author of several public buildings and facilities in the 1980s, Roland Castro is best known for his stance against the urbanism of towers and bars typical of the Trente Glorieuses period, as well as for his efforts to “remodel” large housing estates: in Lorient, for example, or Jean Dubuisson's Caravelle in Villeneuve-la-Garenne.

In the early 1990s, he was commissioned by Charles Pasqua, then President of the Hauts-de-Seine General Council, to “redesign” the department. This led the agency to work on the La Défense site. The company built Les Villages de l'Arche, the Colisée, the Pullman Hotel and worked on the development of the circular boulevard.
