Chajja.- an old architectural feature of Indian origin is replicated in modern buildings!!

 A chhajja,( a word of Urdu origin meaning brim) an overhanging eave or roof covering is an essential part of Indian architecture  and it  has found a permanent place in the Indian Architectural  nomenclature. Tt protects the windows, etc  just the way a  hat with a wide brim protects the wearer from the sun glare and rain.  Normally located  above the window or balcony on the outside of a building with a wall or railing around it. A functional and decorative element native to India providing shade and protecting the inner parts from rain. In the English language it is similar to  'Sun Block' and ' Eaves. On the ground floor chajja', a projected feature not only does the above functions, but also prevents rains damping the walls all around.   Its size may vary  and commonly it  is  from   2–5 feet in length and 2 feet wide

In the last a few decades this important part of a structure is made of  cement concrete, wood, fibers sheet-asbestos materials, etc. it may be sloping or horizontal structural overhang  at the lintel level and in the early buildings  a small cornice band  above the void, doing the same function  acting as a drip mould, directing the water flowing down the surface away from window. Near the windows and entrances it will reduce the sky or sun glare while looking out. Sometimes in the old structures such horizontal projections  all around the building at the lintel level  will direct the water away from the wall. 

Instead of deep overhang sloping roof an alternative technique is followed. The  sloping  chajja. above the outer windows or entrances  may be supported by  a wooden or steel bracket. In the building with flat roof  above the windows small stone slabs are fixed with some decoration. 

Many buildings across  post independence India have concrete slab projection as chajja and for decoration purpose it may be laid with red tiles. 

Traditionally, most regions of India did not have the projection, nowadays called as concrete chajja. The sloping roof overhang was so deep; it would cover up the wall and window opening. Alternately, there would be a wooden bracket supporting the sloping sunshade over the windows. In case of flat roofs in hot arid regions, small stone slabs or sometimes an ornate window design as a box can be seen. The formal concrete slab projection as chajja appears to be a post-independence phenomenon,
