Jean-Jacques Deluz

Jean-Jacques Deluz, born April 8, 1930 in Lausanne and died April 30, 2009 in Algiers, was a Swiss architect and urban planner. He settled in Algiers in 1956, where he lived and worked until his death in 2009, when he was buried. Through his work—his buildings, his writings, and his teaching—he is one of the most important figures in modern Algerian architecture.

Jean-Jacques Deluz, born in Lausanne in 1930, arrived in Algiers almost by chance in the mid-1950s. Upon his arrival in 1956, the young Swiss architect joined the firm of architects Alexis Daure and Henry Béri, before collaborating on urban planning with Gérald Hanning at the Algiers Planning Agency, which he took over as director in 1959.

Equipped with a solid background and a strong presence within Algiers' modernist elite, alongside Louis Miquel, Marc Emery, Roland Simounet, and other architectural figures, he opened his own architectural practice after independence. In 1964, he began a teaching career that lasted until 1988, training generations of students in classical and modern architecture, while also imparting to them a keen vision of the city.

An architect and urban planner, Deluz favored a modest and demanding approach, combining respect for sites, territories, and landscapes. Faithful to the teachings of Fernand Pouillon, he rejected ostentatious gestures. His achievements included the extension of the Polytechnic School of Architecture and Urban Planning and later the project for the new city of Sidi Abdellah, which would remain very dear to his heart.

The Algiers School of Architecture was originally a project conceived by architect Oscar Niemeyer. To accommodate the ever-growing number of students, in the 1980s, architect-teacher Jean-Jacques Deluz was entrusted with the expansion of the School of Architecture. While respecting the continuity of the overall layout, Deluz optimized the space and cost of the project by contrasting the elongated and fluid volumes designed by the Brazilian architect with the rigor of a grid and superimposing simple cubic volumes that adhere to a rationalist vision.
