The Dugkhang or the Main Hall in centuries past was used as a detention room and later as cold storage. Traditionally the Sikkimese did not reside in the ground floor as a safety precautionary measure against wild animals & wild "spirits" (pyathem).
The special feature about this room is the three foot wide walls and a lone traditional(wooden) pillar in the centre holding up the entire house. The room remains cool in the summer and suprisingly warm during the winters. It is now an exclusive dining hall.
