This building located at Jendral Ahmad Yani street is the first building in Sumatera ever to use an elevator (in 1910). The elevator is still functioning well to this day. This building used to be owned by Julianagebouw, until it was taken over by British plantation company, Harrison & Crossfield Ltd, which was then renamed into PT. Perkebunan London Sumatera Indonesia. This triangular building is made of Aberdeens granite as ballast, brought all the way from Britain. The building has a British Colonial Style influence in architecture as seen in Singapore, Malaysia, India, as well as other former British occupied lands. There is also a duplicate of this building in London.
