Granaries on Raised Platform
Concept and Structural Design
The house on raised stilts is an age old structure originating in the
Himalayan ranges. It was mainly seen amongst the Mongoloid tribes that such
houses were made. Houses on stilts are predominantly found India, China,
Tibet, Thailand, Cambodia and in pockets of Bangladesh. Significantly it is
seen that people live in such houses were the landscape is mainly undulating
land mass. On the other hand people living in areas where there is high
precipitation and moisture content both in the air and in the soil has led
them to design houses on stilts. In North Eastern India the tribes living on
houses on stilts mainly live in hills amongst thick vegetation, forest and
by the banks of rivers.
The Mishing tribe of Assam lives along the river Bramhaputra mainly
concentrated on the North Banks; they are believed to be the descendents of
Mongoloid origin who have settled by the banks of the mighty Bramhaputra
mainly in Upper Assam. Some of the country cousins of this tribe are the
Hillmiris who live in Arunachal Pradesh; the pattern of weave, housing
design and food habits are similar amongst these two tribes and the Mishing
are also known as Miri in Assam. Traditionally people of the Mishing
community live on houses on stilts; these houses and the flight of 5-7
stairs leading to these houses have religious and social beliefs and
practices attached to it. A guest is accepted or a new bride only becomes a
part of the family when led up the flight of stairs.
The house on stilts is a big hall with a central kitchen for a large joint
family. A lower part of the house is used to provide to shelter to animals
that every household rears and in river side villages where people lived in
flood planes animals were provided shelter on the raised home with people.
On the other hand these houses were also made to provide protection from
wild animals. Apart from the main house there is a traditional granary on
raised platform. It is said by the elders of the Mishing tribes that the
present river banks of Bramhaputra were tall grassland and also had very
thick vegetation of reeds leading to favourite game area for wild elephants.
They say that elephants do not attack houses on stilts and therefore not
destroy even the granaries; the grains are also protected from moisture,
rodents and floods.
North East including Assam is rich in sylvan resources and most of its
forests are richly stocked with bamboos and canes of various species. Bamboo
is a raw material of great versatility and forms an integral part of the
lifestyle and economy of Assam. The major components of these houses are
bamboo, cane and palm leaves for roofing. Bamboo is widely used for pillar,
linter, floor, roof, door etc. Bamboos are aptly called the poor manís
timber and are found in great abundance in the North Eastern region of
India. Their strength, straightness and lightness combined with
extraordinary hardness, range in sizes, abundance, easy propagation and the
short period in which they attain maturity make them suitable for the
