The theatre is situated at the Pig Market/Varkensmarkt/Marcé aux porcs. The overall form of a theater is already defi ned for the larger part by the problem of acoustics; how to solve it.In essence the Bronks is no more then two large boxes fi t together with around it enough margin for circulation and acoustics. Below stage level ʻhalf under under street levelʼ, we have put the reception, sanitary facilities and techniques. Under the roof top sit the administration and café cum foyer.Façade and roof are then literally and figuratively spoken loose standing problems that are subject to quite a number of boundary conditions. Building in an historical center is no sinecure. It demands the perfect alignement with the adjacent roofs of neighbouring houses, to keep to the rhythm of windows and façades such displayed in the surrounding block.Contrary to the surrounding historical houses, we are dealing here with a public building. How can we make it as yet visible ? In contrast to the closed back façade, which shields off the ʻbigʼ theater hall, we have chosen for an open glazed front façade two meters behind, the wall of the (repetition)hall can slide open. It allows to put a play on stage with ʻrealʼ street animation at the back. Pedagogy is part of the job of a youth theatre and more precisely working with ʻthe streetʼ.Structurally our front façade is made up out of a plane in which we have cut 2 rectangular holes. What remains is a passe-partout which we have turned inside through and what brings about that specific horizontal partition. We call it the champagne bar being a step up to the café/foyer. Itʼs not the only partition that we will use.Between the two ʻOʼs that form the theater halls we have introduced a ʻ7ʼ, a septum, being a rotative wall partition (at both sides being cladded with mirrors) and what can direct public and private traffi c of people into interchangable alleys. For all itʼs a plaything, but it tries to meet also to the demand for a fl exible multifunctional building. The septum ranges amongst other movable items such as a telescopic seating area, a mechanically heigtened stage fl oor, in the big hall, the acoustic sliding walls that can turn the front hall into two repetition halls.By placing two staircases against each other in the central circulation zone, one private, one public including the septum in its middle; the entry to the halls can vary.The theater can function next to the repetition space or in the festival period two plays can be performed simultaneously. Stage 1 takes the stairs on the right, stage 2 takes the stairs on the left, or vica versa. One can either choose to enter the hall in the center or at the rear and downstairsinstead of upstairs (given the fact also whether the telescopic seating area is pulled out or not). The reception below stage level is rebuildable into workshops.The café has its own staircase and elevator and can function independently from the theater. It offers a great view over the Pig Market and theBrique quays. Finally other scenarioʼs of entering the buildingare possible. For instance through the ʻcoach houseʼ. Before, the oldest ʻbreedhuisʼ, literally translated as ʻbroad houseʼ of Brussels wasstanding on this site and which became demolished in 1989.
