 Although historic sources are divided on whether Tranovola, Bevato or Marivolanitra was the first two-storey house at the Rova, the innovations embodied in these buildings and particularly in Tranovola underscore the rising influence of foreign architectural norms in Imerina.Tranovola is widely represented by historians as the first true example of the hybridisation of Merina architectural norms and those of Europe, and its design served as a model for the larger Manjakamiadana palace some years later.The innovative features of this building and the Manjakamiadana it inspired—particularly the verandas supported by exterior columns—became the new norm in highlands architecture, especially upon the adoption of brick as the principal building material.
