Unlike English or French oriel windows which are actually bay windows from the main wall of the building,  jharkhas are not only formal, but also ornamental to give a better look to the façade of the building. Construction of jharkhas was prevalent in the 19th century particularly in North Indian states .Opulent rulers and people with exalted status gave more importance to aesthetic, hence they preferred  richly ornamental jharkhas with striking canopy to enhance the grandeur of their buildings. Many palaces and havelis  in the north  have  ornate jharkhas and they are quite awe-inspiring. The builders and artesian were richly talented and imaginative and it is a time-consuming work to  successfully finish such  architectural  elements.
