About The One Alma Paris
- L'Air Liquide filed the building permit in July 1955 so Démaret's block could extend the company headquarters next door. The hotel conversion in 2014 kept the original façade.
- Cleton's pictures included a Jean-Pierre Pinceman in the foyer, a sculpture by Czesław Zuber, and a Jan Voss painting in the lounge.
- Rue Cognacq-Jay takes its name from Ernest Cognacq, founder of La Samaritaine, under a decree of January 1928. The hotel is in the 7th, a few minutes from the Pont de l'Alma.
- Entry-level rooms start at 237 sq ft (22 m²).
History
Jean Démaret designed 10-12 Rue Cognacq-Jay as offices for L'Air Liquide. The building permit was filed in July 1955, the block went up around 1957, and it became a hotel in 2014 without losing the modern façade. Eric Cleton opened Hôtel Juliana in 2015, naming it for his children Julien and Anna. H10 Hotels bought the forty-room house in May 2025 and renamed it The One Alma Paris.
The setting
