The historic Amsterdam canal house on Keizersgracht 516, which dates back to 1882, used to be an average canal house. It now accommodates Gallery Borzo, which opened in January 2006 after a period of careful reconstruction and restoration. When the building was assigned for reconstruction in October 2004, its previous structural alternations were rather disguised. At the beginning of the 20th century the building was converted into a warehouse. In 1932 it was once again remodeled, this time into a bookstore with various routing paths. A hanging steel construction was added during this period to allowed the façade to be opened up andallow more natural light into the deep and narrow bookstore. A vertical column containing the book elevator spatially balanced these mostly horizontal elements.In the 1970’s an art dealer bought the building, and though he left the interior intact, eventually walls, floors and extra spiral stairs were successively added over the years, making it rather difficult to distinguish original elements from those that were not. In order to uncover and integrate the original design from 1932 within the layout of Gallery Borzo, the building was completely stripped. By taking away the 1970’s modifications, the original features such as the façade, portal, level division, hanging circulation and former book elevator, reappeared.
