The wooden architecture is formed on the basis of a box-shaped frame. The frame has many types of trusses, the porch columns stretch up to firmly attach the beams and the column heads in 3 dimensions of space. The beams stretch across the porch, mortising and mortising into the column heads, creating more solidity in the middle. The Ca Communal House is covered with fish-tail tiles, with a layer of ancient moss on top of the tiles. The communal house roof spreads out widely, with the four corners of the roof curved to create a curved eaves. Under the roof is a column system of 24 parallel columns supporting the heavy roof. The longitudinal and transverse beams are connected by carefully reinforced mortise and tenon joints, fitting tightly together to form a sturdy frame.

In the 16th - 17th centuries, the Ca Communal House was built with a sanctuary behind the middle room as a private, solemn place of worship, separate from the surrounding area. Based on the architecture and worship, it is known that the Ca Communal House was built in the 16th - 17th centuries, at first as a temple to worship Cao Son and his generals, and it was not until the Le Dynasty that the Communal House was built on a large scale and as ancient as it is today.
