The Appallagoda Ambalama has a floor area of approximately 80 square metres and it measures 5.6 metres from floor to pinnacle. The roof is supported by two sets of stone columns, 12 externally and 4 internally. Inside, around the Ambalama, there are seats made out of stone. Caste differences play a vital role in the management of society, especially in an area such as Kandy, and this is depicted by the level change seen in the seating area.
At the top of the roof there is a brass pinnacle which symbolises the architectural pattern of that period. A prominent feature of this Ambalama is the stone "pinthäliya", a traditional container in which drinking water is stored, that is situated in front of the Ambalama. Another prominent feature are the two broken stone columns in the north-eastern side of the Ambalama. The villagers in the area say that this was done deliberately when the Ambalama was built in order to ward off inauspicious omens.
