Auditorium Design Concept

 

Auditorium Design Concept   

The auditorium is a big room building facilitated with sitting arrangements for Audience and Stage for performers for presentation, acting, and motivations.

The uses of Auditoriums are several depending upon the type of requirement of the public as it maybe a Theatre, Cinema, Conference Room, Meeting room, Assembly Hall, Award showroom etc.

Shape of Auditoriums

Auditoriums  may be constructed in any form but mostly it is constructed in rectangular and sector of circles or Curves considering availability of the land size and orientation of the building.

Size of Auditoriums

The most important thing in the design of the Auditorium is sizing to facilitate Audience and performers avoiding all possible problems.

1- Size of sitting area in Curvy rows

The seating capacity for 1 person should be 6 Sft to 7 Sft which includes a minimum passage area of 5 Sft for 1 person.

2- Size of sitting area in Straight rows

The seating capacity for 1 person should be 6 Sft to 7 Sft and the minimum area of    5 Sft for a person should be added for passages.

3- Volume Capacity for 1 Person and Height of Auditorium.

volume required for each person in the auditorium should be 124 Cft to 160 Cft with a minimum height of 20 Feet and Maximum Height can be calculated using nominal volume and area required for one Individual.

 4- Seating Alignment.

Seating alignment should be staggered in a way so that spectator in any line is not sighting over the head of an individual sitting in front of him.

5- Head Room

Minimum head rooms under the landings and cantilever portions should not be less than 7 ft.

6- Area of Ventilators and Door , Windows.

The area of Doors, Windows, Ventilators adjacent to in an open space  should be 15% (In case of Air Conditioning of Hall)  and 20% of Total Floor Area in case of Fans and Exhausts fans ventilation.

 7- Size and spacing of chairs /Seats.

The width of seats should be 19" to 21" and the back to back distance of seats should be 3 ft to 3'-6" and the crossing passage in front of chairs should be 1'-6" to 2ft for traveling in between the chairs back and front. Seating the angle should not be less than 65 degrees.

8- Level of Stage.

The level of the stage should be 3'-3" higher than the lowest level of flooring in front of first-line from the stage.

9- Arrangements to avoid resonance.

Sound absorbing material should be used on walls, round walls should be avoided in Auditoriums. Thick carpeting also helps to control echo problems.

10- Design of stairs.

Minimum width of the stair should not be less than 6'-0" and the minimum size of the tread and rise should be 12"x6".

 11-Position of Screen

The position of the screen should be fitted in a way that the angle eyesight of the person sitting in a front line from the top of the screen may not be more than 34 degrees.

12-Structural stability of Auditorium

Structure of Auditorium building should be designed by competent designers and good construction practices should be adopted to complete the building.
