Explanation:

There are three subtypes of Nagara temple depending upon the shape of Shikhara:
Rekha Prasad / Latina
Simple Shikhara - Square at the base and the walls curve inward to a point on the top.Latina types are mainly used for housing the garbhagriha.The top is called ‘latina’ or the rekha-Prasad type of Shikhara.
Phamsana:Phamsana buildings tend to be broader and shorter than latina buildings.Their roofs are composed of several slabs that gently rise to a single point over the center ofbuilding, unlike the latina ones which look like sharply rising tall towers.They do not curve inwards, instead they slope upwards on a straight incline.In many North Indian temples Phamsana was used for mandapa and latina for Garbhgriha.
Valabhi:Rectangular building with a roof that rises into a vaulted chamber.They are usually called as wagon vaulted buildings.
