The new Vidhan Sabha Complex consists of six-sectors arranged to give an overall circular plan of 140m in diameter covering an area of about 29000 sqm. Within the extent of the building, the existing ground level falls by approximately 8m which has been integrated in the design in an imaginative manner and has resulted in two to five storey buildings.
