 Another wooden palace, Tranovola ("Silver House"), was under construction at the same time as Bevato and is considered by historians to represent the first true hybrid of Creole and traditional Merina aristocratic architecture.Its innovations included a roof of wood shingles, a second storey, the addition of a veranda, glass windows, multiple interior rooms (as opposed to a single open interior space) and the use of curved shapes as design elements.Historic sources offer conflicting accounts of these two buildings.
