The former warehouse and national monument Jobsveem, also known as St. Job, on the quay of the Lloyd Pier in Rotterdam, has been changed significantly. The design by Mei in collaboration with architect Wessel de Jonge breathes new life into the old warehouse. Since its completion in 1913, is was extremely introverted. This was done to protect the stored goods from too much daylight, rain and wind. The structure involved the use of construction methods that were very advanced for their time: long floors (130x25m) with cast-iron columns of different heights. Converting it to apartments and commercial spaces was an opportunity to bring daylight into the building with 3 glazed atria. The light courts of glass and steel emphasise the monumental components that have been carefully restored. They are lively, light spaces where residents can meet one another. In warm weather, and also in the event of calamities such as fire, the glazed roof opens and a light breeze blows through the atrium.
