Two inclined wings, 9-storey high join with the central core at top to create an open attrium. Each typical floor is 11m x 25m column free using one way ribs. Alternate floors are tied together with post tensioned cables. The building houses the offices of the National Cooperative Development Corporation.

The Secretariat Building was designed by the prominent British architect Herbert Baker in Indo-Saracenic Revival architecture. Both the identical building have four levels, each with about 1,000 rooms, in the inner courtyards to make space for future expansions. In continuation with the Viceroy's House, these buildings also used cream and red Dholpur sandstone from Rajasthan, with the red sandstone forming the base. Together the buildings were designed to form two squares. They have broad corridors between different wings and wide stairways to the four floors and each building is topped by a giant dome, while each wings end with colonnaded balcony. Much of the building is in classical architectural style, yet it incorporated from Mughal and Rajasthani architecture style and motifs in its architecture. These are visible in the use of Jali, perforated screens, to protect from scorching sun and monsoon rains of India. Another feature of the building is a dome-like structure known as the Chatri, a design unique to India, used in ancient times to give relief to travelers by providing shade from the hot Indian sun.
