The communal house was built on a high land belonging to the territory
of three villages: Co Dien, Co Ngo, Dong Phu in Thanh Tri - Ha Noi.
The communal house was designed following the style of "Chong diem tam
mai" (two roofs overlapping each other making four couples of roofs
corners) with dragon shapes on the top towards the ridge of the roof.
At the very center of the roof, there is a sun shape. The pillars of
three - entrance gates are quite big with Chinese parallel sentences
carved on their body . There are two young lions huddling together on
the peak of the pillar "Phuong dinh" (a place with four pillars and a
roof without wall used for preparing offering gifts) constructed
perdendicularly to four long rafters from the main column to the corner
of the roof supporting the roofs above and under. All of them was sculp
tured with dragon shape according to the scenery of Nguyen dynasty. The
middle chamber includes five rooms with many images of dragons, flowers
on curtains... and a set of carpentry with model of "chuong giuong gia
chung xa nach" (a pattern of architecture) with is usually used in
designing temple and pagoda in Viet Nam. The large chamber has also
five rooms and one feign door in front. Its roof was covered with
internal tiles serveral engravings following themes such as dragon,
phoenix, unicorn and tortoise appearing on carpentries and walls
combining two ends of the chamber (cuon nach). Inside the temple, there
are three rooms. Carpentries here were designed simply with the place
for worshipping covered with flooring planks with ancestral tablets and
statues of tutelary spirits.
