The Old Stock Exchange Building is a distinctive example of Neo-Classical architecture enriched with Indian decorative elements. It is a three-storeyed structure comprising a ground floor and two upper floors, with a prominent façade characterised by alternating balconies, classical detailing and florid ornamentation. The Ahmedabad Municipal Corporation specifically identifies its European-style façade, Neo-Classical features and Indian elements as defining architectural characteristics.

Particularly notable are the jharoka-style balconies, which introduce a distinctly Indian architectural vocabulary into an otherwise European-inspired composition. Later extensions incorporate Art Deco elements, reflecting the building’s architectural evolution over time. The structure also contains three large halls arranged vertically, historically accommodating the activities of the stock exchange.

Dhrangadhra sandstone, transported from the Surendranagar region, forms a defining material of the building and is responsible for its richly carved exterior. Ornamental stone carving, combined with classical proportions, timber entrance doors and decorative detailing, demonstrates the craftsmanship of the period. The surviving façade therefore represents a compelling synthesis of European architectural principles and indigenous craftsmanship.
