In the 1800s the next significant building type emerged in Bhutan
with the large houses built by the wealthy. However, the style changed little from
the earlier Dzongs, except these were built for living and were generally only built
by the local wealthy, limited the number ever built; these are primarily found in
the country's west, in Bumthang, Paro, and Trongsa.
On a smaller scale, numerous houses were built and can still be seen in the cities
of Paro and Thimphu with a little searching or aimless wandering. Few of these hold
any historic significance and they display the same architectural features found
in other buildings in the country. However, these houses vary much more than the
Dzongs or large houses; in the south the houses are primarily made of bamboo, while
in the mountains they tend to be made from stone. Most of these local homes though
are just made of clay and wood.
Traditional architecture continues to be built in Bhutan
today as there are laws dictating the style of buildings that can be built. All
new construction must contain arched windows, multi-colored wood, and sloping roofs;
additionally, nails are not allowed.
