A wooden chhajja is an architectural element commonly found in traditional Indian buildings, especially in regions with hot climates. It is a type of projecting overhang or eave made from wood, usually placed above windows, doors, or along walls to provide shade and protect the structure from rain and direct sunlight.
The wooden chhajja not only serves a functional purpose but also adds aesthetic value to the building, often featuring intricate carvings and ornamental brackets.
These structures help in enhancing thermal comfort inside buildings and are a characteristic feature of vernacular architecture, blending utility with craftsmanship and cultural expression.

In construction, a wooden chhajja detail drawing provides precise specifications and dimensions for the design, materials, and assembly of the chhajja (overhang). It typically includes the following components:
- Plan View: Shows the chhajja’s projection from the wall and its length along the façade.
- Sectional View: Illustrates the vertical slice through the chhajja, showing thickness of wooden planks, support system, and slope for rainwater drainage.
- Elevation View: Displays the decorative elements, brackets, and how the chhajja appears from the front.
- Support Details: Indicates wooden brackets or cantilever beams (like timber rafters), their joinery (dovetail, mortise-tenon), and anchorage into the wall.
- Material Specifications: Lists the type of wood (e.g., teak or sal), finishes (like polish or paint), and any waterproofing layers.
- Fasteners and Joinery: Notes the types of bolts, screws, or traditional joints used to assemble and fix the chhajja.
These drawings ensure accurate execution on site, balancing structural integrity, weather protection, and traditional aesthetics.
Such detailed drawings are essential for craftsmen and builders to maintain both the structural performance and the traditional architectural character of the wooden chhajja.
