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.
