The VN technique lends itself well to three levels of customisation:

 the technique can be adapted to suit the needs and financial resources of a wide range of clients, from the poorest rural families to wealthier urban ones
 the technique allows for later extension of a building, by lengthening a vault, by adding further vaults on the side of an existing one, or by adding a second storey onto an existing single storey building; these possibilities are likely to increase the popularity of VN architecture, as homes can be ’grown’ to match developing family needs
 it is a straightforward matter to re-arrange the interiors of VN buildings`(e.g the adding or removal of internal partitions, the opening or closing of doorways, and window and alcove arches)

The range and diversity of popular adaptations of the VN technique demonstrates the richness of the VN concept. Churches, mosques, school classrooms, dispensaries, agricultural buildings, verandahs, two-storey houses etc are enriching the range of applications of the VN technique. These possibilities are firmly based on the original simplicity, modularity, and strength of the concept.
