 After the first corner post of the building was raised on 25 April 1865, work continued for two years before Manampisoa was complete.Measuring approximately long, wide and high, the structure was built using traditional vertical wood wall boards topped by a wooden roof and featured sliding windows protected by heavy wooden shutters.It was built on a site formerly occupied by the wooden house called Marivolanitra, which was relocated to Mahazoarivo to make room for the new building.
