DIFFERENT TYPES OF CONTEMPORARY THEATRES THRUST STAGE A theatre in which the stage is extended so that the audience surrounds it on three sides.

ARENA STAGE Any theatre space in which the audience surrounds the stage area

END STAGE The audience seating and stage occupy the same architectural space, with the stage at one end and the audience seated in front facing the stage.

6 The Theatre Projects


BLACK BOX PROMENADE A theatre without fixed seating in the main part of the auditorium – this allows the standing audience to intermingle with the performance and to follow the focal point of the action to different parts of the room

A flexible theatre usually without character or embellishment—a “void” space that may indeed be black, but isn’t always.

STUDIO THEATRE A flexible theatre with one or more audience galleries on three or four sides of a rectangular room.

7 The Theatre Projects


SHOE BOX CONCERT HALL RECITAL HALL A space designed for soloists and small ensembles (up to chamber orchestra size), with a seat count typically in the range of 150 to 800. This form is a descendant of the court music rooms of the Renaissance.

The shoebox form has high volume, limited width, and multiple audience levels, usually with relatively narrow side seating ledges.

VINEYARD CONCERT HALL Some modern concert halls have audience seating in terraces reminiscent of a vineyard. The seating may completely or partially encircle the concert platform.

8 The Theatre Projects


MULTIPURPOSE

OPERA HOUSE An opera house is a proscenium theatre in form. Seat count ranges from 1,200 to 2,000 with an upper limit of about 2,400 seats. The auditorium is almost always multilevel with side tiers or boxes to enhance visual and aural intimacy..

The auditorium form is heavily influenced by the acoustic requirements for symphony, while the stage house is designed to meet the needs of opera and musicals. These rooms are designed with the ability to change configurations

MULTI FORM THEATRES A multiform theatre can be reconfigured to change the actoraudience relationship and the seat count. By moving large architectural elements, the one-room form of the concert hall can be transformed into a two-room theatre

9 The Theatre Projects


SHOW ROOM

MULTI USE THEATRE This is a proscenium theatre designed primarily for amplified sound. The room acoustics are usually “dry� with little adjustment available, making these rooms unsuitable for un-amplified acoustic music.

The term showroom usually implies an entertainment venue connected with a casino, hotel, or resort. A showroom may be designed to accommodate variety or headliner acts, or it may be purpose-built for a specific production

ENVIRONMENTAL THEATRE The audience space and performance space are sometimes intermingled, and the action may be singlefocus or multiple-focus. In environmental theatre, the physical space is an essential part of the performance

10 The Theatre Projects


PROSCENIUM In a proscenium theatre, the stage is located at one end of the auditorium and is physically separated from the audience space by a proscenium wall.

COURTYARD STAGE central area is flexible, and can be configured into arena, thrust, end stage, and flat floor configurations.

THRUST AND OPEN STAGE Some larger drama theatres take the form of a thrust stage, with the audience surrounding three sides of the performance platform..

BALCONY Depth of balcony Overhang (h)

Sight line to front one-third of ceiling Height of balcony Opening (h) Sloped soffit (performers on stage should have line-ofsight to soffit

In some instances in which a large seating capacity is desired, it is necessary to resort to a balcony in order to avoid the excessive viewing distance that would otherwise develop. Balconies may be introduced in small theatres as well to bring the audience closer to the actors.

25 Architectural Acoustics, M. David Egan


‘Flying Balcony’ (can have D>H because reverberant sound energy will be directed towards rear seats underneath)

FLYING BALCONY

The cantilevered balcony is open at the rear, allowing reverberant sound energy to surround the audience seated underneath.

Seats in ‘shadow’ of balcony overhang (no line of sight)

Balconies should be provided considering that the sight lines (max 30 degree from horizontal) does not get hampered and also reflected sound path which can create a dead spot. FAULTS IN BALCONIES 26 Architectural Acoustics, M. David Egan

The slope of the main-floor seating would also be increased for one-row vision. Two-row vision though not ideal is made more acceptable by staggering the seats to permit a view between the heads of the persons in the row immediately in front.

Street Furniture Street furniture is a collective term for objects and pieces of equipment installed along streets and roads for various purposes. It includes benches, traffic barriers, bollards, streetlamps, signs, bus stops, public lavatories, fountains, memorials, public sculptures, and waste receptacles.

Street furniture can reflect local culture or famous aspects of where they are located, as here at Lyme Regis, where the ammonite-design streetlamps reflect the town's location on the Jurassic Coast, a World Heritage site. 66 Whale Tail Rest Pavilion became an identifier
