The gabled walls are triangular in shape built after the ring beam. These walls follow the triangular trusses of the roof. They are slanted to both sides. They adjust to the slope of the roof. These walls provide cover at the end of buildings where the roof rises above the windows and stairs. It is important to build a strong wall due to the lateral forces of the building. These forces include torrential rain and wind. The finishes are similar to the external walls of the house.

Gabled walls allow roof space to be used in buildings. In a multi-unit building, they offer privacy. This is because they rise to ceiling level. When building a house, make sure the ring beam and wall plate are properly attached. This is to ensure that the gable wall only carries the roof along with the trusses. Sometimes the roof can be sloped and therefore follows the line of the gable wall. Therefore, the mark is attached to these walls.

After the ring beam is cast, the gable wall can be erected. A piece of wood is cut and nailed in the center of the beam. This will be the line to build the right angle of the triangular roof. This wood is usually the height of the ceiling to be built. It is also the point where the ridge will begin along the entire roof at the top. A rope is then nailed to this wood. Mark the height of the wall on both sides from the center forming the two hypotenuses of the ring beam.

The gable wall is built like the other walls of the house. The iron hoop reinforcement is used in all alternative courses. The wall is built backwards, forming a triangle in line with the rope. What remains are steps on either side of the wall from the center. These are filled once the roof is completed. Holes should also be left where the roof straps will sit. When the roofing is completed, the holes are filled. Subsequently, the desired wall finishes are applied to give a good aesthetic to the facade of the wall.
