420 Julia Street is a masonry structure that was originally built as a private residence in the 1840s and converted into a warehouse in the 1880s. Located in New Orleans’ Warehouse District between Tchoupitoulas and Constance Streets, the building is notable for its arched brick openings and iconic, blue exterior double doors. It has been transformed through the renovation of the two-story, 46,000 SF historic structure and construction of a five-story, 117,000 SF new addition. The revitalized property is now a mixed-use development with a Common House members’ club and Memoir Warehouse District hotel and residential community.

The Common House social club occupies the historic first floor, and features two event spaces, the social hall, dining rooms, open work spaces, a fitness center and rooftop pool deck.

Memoir Warehouse District offers 43 hotel keys on the 2nd floor and 70 apartments on floors three through five.

Since 420 Julia is part of the historic Warehouse District, renovation work was coordinated with the Historic District Landmark Commission. Its timber structure was shored up and repaired, and its exterior masonry walls and original detailing were rehabbed. The roof was redone and new building systems were integrated. The iconic, blue exterior double doors, and exposed brick and concrete floors were kept in place as finished surfaces.

The new addition references the brickwork and scale of openings to the original building, yet it maintains a contemporary aesthetic of its own. The historic building and new addition come together to carve out a long inner courtyard, which allows daylight to penetrate into the heart of the deep site.
