The document describes the construction details of a slanted roof structure. Cross-halving joints are used to connect the roof frame. L-shaped brackets connect the roof to the main columns, transferring loads directly from the roof to the floor and supporting the columns. Flat-shaped brackets are also used, connecting the roof frame to other parts of the columns. Secondary columns are angled and attached to the floor and roof frame with screws to provide support and stability. A vertical column is added to increase the height and make the roof slanted on one side.
