At 19–25 rue Boissonade in Paris’s 14th arrondissement, a former municipal office building has been converted into social housing by the Régie immobilière de la Ville de Paris (RIVP), the project’s developer. 1 Built by the City of Paris in 1947, the building was acquired by the RIVP in 2019; rehabilitation began in 2021 and was completed in May 2024. 1
The project retained the building’s distinctive, prow-like form and heritage character while extending it to create 20 social-rental homes and a ground-floor activity space. 1 The apartments range from T1 bis to T5: eight T1 bis, three T2, five T3, one T4 and three T5. 1 The City of Paris reports that 20 families now live in the building. 1
The five-storey building includes a shared rooftop terrace on the fifth floor and a planted terrace of 130 square metres on the first floor. 1 Apartments have large glazed openings, sliding aluminium joinery and external sunshades; the reported energy-performance rating is C. 1 The works cost €7.1 million. 1
The project’s scope was the adaptive reuse and extension of an existing office building, rather than new-build housing: municipal offices were replaced with homes while the existing structure and its architectural character were retained. 1 The available project information identifies the RIVP as the acquiring and rehabilitating organisation; it does not specify individual project leads or a founding date for the project. 1
