An auditorium offers immense potential to increase connections with community to a large extent. From the literature, it is observed that most of the auditoriums were designed for only two-way slab and by considering different types of footing. Analysis and designs were not available for auditoriums with different types of slabs. Comparative studies are also not available for the same and that necessitated this project. The main objective is to plan, analyse and design an auditorium with one-way, two-way and grid slab. The project involves the planning, analysis, and design of an auditorium with a seating capacity of 500 people as per the of (IS 2526-1963 [5]). The plans of an auditorium were developed using AutoCAD software. Analysis and design of an auditorium were carried out using STAAD Pro software. An auditorium with two-way slab is found to be economical compared to an auditorium with one way slab and grid slab based on the volume of concrete required. The critical elements of auditorium such as slabs, beams, columns and footings were manually designed for the forces and moments obtained from the analysis. From this project, it is concluded that the grid slab offers lesser thickness. However, by considering design an auditorium with two way slab was found to be more economical.
