What is the purpose of chajja?
The word commonly known today as ‘chajja’ is the projected element just above the window, which shades the opening, stops rain from entering the room and reduces sky glare while looking out of the room.
What is a chajja in architecture?
A chhajja is an overhanging eave or roof covering found in Indian architecture. Its function is similar to that of other overhangs or eaves in that it protects and adorns entrances, arches and windows from the outside elements. Some styles of roof can be considered large chhajja as well.
Can we construct wall on chajja?
No, it won’t carry any load or support building like as beam and column does, It has more architectural purposes than structural.
What should be the length of Chajja?
Maximum length of the board should be 180 cm.
What is sunshade in civil engineering?
A sun shade or ‘brise-soleil’ (derived from the French word ‘sun breaker’), is an architectural feature of a building that reduces heat gain by deflecting sunlight. A history of providing shading from the sun is found in the early Greek and Roman buildings in the form of porticos and colonnades.
Can we construct Chajja without lintel?
Exposed brick walls may look nice with the plastered RCC band, yet they can also be built without the lintel being visible. The outer edge would have a brick, with the thin lintel behind. If it is a hollow clay block, the concrete can be filled within the hollow of the block, creating beam-like support.
What is the difference between Chajja and sunshade?
Traditionally called the chajja in North India, it comprised large roof overhangs supported by carved brackets, primarily seen in traditional Rajasthan, Gujarat, Punjab and UP. A sunshade in today’s context could refer to any horizontal or vertical component to protect the building from climatic elements.

Can we build wall on cantilever?
There is no simple answer to this, you have to calculate it. The length of the cantilever is very important as it will influence the moment it creates in the masonry wall. You have to simply analyze the structure. You need to design the structure accordingly.
What is thickness of Chajja?
Boards of hardwood or softwood are of good quality and free of knots. The usual thickness of the boards is 19 mm or 25 mm.
Why is chajja not provided between buildings with very narrow gap?
Between buildings with very narrow gap, sunshades will block the little light and air we can get, hence should not be provided. The buildings shade each other. If the chajja is to mainly serve the looks and elevations, the ordinary flat projection will adversely effect.
Should we use chajjas in north facing windows?
In north facing windows which get minimal rain and harsh light, chajjas can be generally avoided, but for aesthetic reasons. So, fixing a flat slab is not a solution in every context. Imagine alternative, more attractive windows like arched windows, which is liked by many people for the character it gives to the building.
What is the purpose of a chhajja?
Chajja:- A chhajja is the projecting or overhanging eaves or cover of a roof, usually supported on large carved brackets. Usually protects from external sunlight. Also protects from rainwater entering into the building. It also serves as aesthetic decoration with little design on it from architectural point of view.
How do you install a chajja on a curved wall?
One option is to place the chajja also in a curved profile, with the projection anchored to the wall itself. Inverted T sections can be grouted just above the arch following the same curvature which can take flat clay hourdi tiles, stone slabs or even light weight in situ cast RCC slabs.
