The former Johnson & Johnson headquarters is an office-to-residential conversion project in Campo de las Naciones, Madrid, Spain. Argis is developing the former office building into a flex-living complex through its Argis Living Fund II. 21
The plan is for more than 250 flexible-living units. Argis announced the project in February 2025 as part of the launch of its €250 million fund, which focuses on residential and flex-living projects in Madrid. 2 The Brains Real Estate article lists a project budget of €12.2 million for the refurbishment, and mentions a pool and garage; Argis’s announcement separately reports a €51 million investment for the Campo de las Naciones project. 21
The conversion is among the private property refurbishments tracked by Brains Real Estate as starting in 2026. The available sources identify Argis and its fund as the project’s developer and investment vehicle, but do not name individual project leads. 21
