Alexis de Chateauneuf is considered one of the pioneers in the renovation of brick architecture in Hamburg. Several of the buildings he constructed in Hamburg had exposed bricks in the façades, which was publicly discussed. At this time it was common for brick to be covered with gypsum or cement. He made proposals for changes to existing buildings, new buildings and was active in a number of architectural competitions. Many of his proposals were completed. In the district of Neustadt in Hamburg, became a remarkable residential building completed after his drawings. He then received several assignments for both private individuals and for public buildings. He participated in several architectural competitions on stock exchange buildings, first the Hamburg Stock Exchange, later London Stock Exchange (1840). He did not win any of these competitions, but took second place in the architectural competition on the London Stock Exchange.

After the Great fire of Hamburg in 1842, he created several buildings, such as the Alsterarkaden building complex and St Peter's Church in Hamburg. He also contributed to the urban planning in general, and 1842-1847 he was chairman of the technical commission appointed to draw up plans for rebuilding the city.
