In 2013-2018, the orangery building designed for the Hall family by city architect Carl Wilhelm Carlberg, but which fell into disrepair after the Hall bankruptcy, will be reconstructed. Based on Carlberg's drawings, project manager Stefan Günther, PhD in architectural history, has produced architectural and structural drawings. Carpenters, masons and carpenters are working on the construction and the work is proceeding according to plan. The completed orangery will have its original use and house examples of the rich plant collection that Christina Hall listed in an inventory dated July 3, 1809. The Orangery was the most important park building at Gunnebo, a building for both use and pleasure. The southern wing with two corner pavilions served as winter storage for exotic trees and plants, while the portico and the northern pavilion (grotto) were exclusive social rooms. The portico opened out onto two sunken lawns, boulingrins. The eight corners of the lawns were each adorned with a lidded urn and richly decorated with ribbon braids and eagles with spread wings, also designed by C.W. Carlberg. Four urns were produced and put in place for Göteborgs Lustgårdar 2008. Buildings, decorations and vegetation interacted as a whole and gave a feeling of being in more southern latitudes, which deeply impressed the contemporaries. Johan Tobias Sergel wrote, after a visit to Gunnebo in 1801, that he thought he had been in the surroundings of Rome, Tivoli or Frescati.
