Unité d’Habitation Marseille opens with shops, a hotel corridor, and a roof kindergarten as a vertical garden-city of housing access

The Marseille Unité opened in 1952 with double-height flats, an interior shopping street, and a roof terrace intended for gym and kindergarten — a machine for living that tried to pack sun and services into a reconstruction housing bar. In the causal graph this event strengthens Health-System Capacity, a driver that strengthens Hospital beds (per 1,000 people) — an improving welfare path.

The Marseille Unité opened in 1952 with double-height flats, an interior shopping street, and a roof terrace intended for gym and kindergarten — a machine for living that tried to pack sun and services into a reconstruction housing bar. He did not staff the clinic. Split: later cheap copies’ isolation is another row; béton energy is another.

Context

Health-system capacity as driver is analogical: light, air, and a roof for children as a public-health housing idea of Reconstruction. Pessac was the earlier inhabited laboratory. Nantes-Rezé and Berlin Unités are later related buildings, not extra 1952 Facts. Independent locator: Fondation Le Corbusier — English portal at https://www.fondationlecorbusier.fr/en/ (opens in a new tab) (Fondation Le Corbusier).

Later competitions, monuments, translations, UNESCO listings, museums, and adaptations are not converted into extra lifetime acts.

Why it matters

High confidence on 1952. Later copies’ failures do not erase the Marseille services; they are the other row.

Confidence is stated on the impact path, not hidden in adjectives. Mixed effects of Unité d’Habitation Marseille opens with shops, a hotel corridor, and a roof kindergarten as a vertical garden-city of housing access are separate paths.

What the sources establish

Marseille’s city portal independently presents the Unité. Fondation independently documents the programme of services. Britannica independently treats it as a housing prototype. No unique 1952 health-outcome series is invented.

Established: 14 October 1952 opening as housing-plus-services. Not established: a unique infant-health coefficient. Split from ineq and energy rows. Not 2016 UNESCO.

Shared responsibility is part of Unité d’Habitation Marseille opens with shops, a hotel corridor, and a roof kindergarten as a vertical garden-city of housing access. Naming Le Corbusier does not delete co-authors, institutions, or later transmitters. The lag from 1952-10-14 to any measured indicator is not treated as zero. Alternative explanations — weather, other armies, later statutes, or independent cultural change — remain live where the sources do not close them.

That reading is an impact-path choice, not a property stored on the Fact itself.
