My Master's thesis is a plan for a new visiting theatre in the Sörnäinen neighborhood of Helsinki. In this thesis I have researched the relationship between the public theatre building and the city space, the architecture of the theatre building and its operations, and specifically, I have looked at the demands set by visiting performances for a theatre with a single hall. The theatre building is located in the Etelä-Hermanni neighborhood, on the corner plot between Sörnäistenkatu and Lautatarhankatu streets. A state margarine factory currently occupies the site, designed in a classicistic style by Uno Sjöholm in 1924. The margarine factory has been given functions that support a new theatre building. The selected plot is well suited for visiting theatre use. The area does not have a similar building, and the plot is located at the crossroads of entryways that are easily reached by transportation. The new neighbourhoods in the area, namely Arabianranta, Kalasatama and Hanasaari, will provide more clientele in the future. The building's space plan consists of public facilities, such as the lobbies, cafe and restaurant, and the performance hall with the production spaces that support it. The floor area of the building is 11 169 m2. A maximum of approximately 1500 people may fit in the performance hall. The building has been covered with punctured, patinated copper sheet plate coffers, except for the glass facade on the main entrance side of the building. A red-brown facade treatment fits in with the buildings in the area, which are mostly made of red brick. This solution stresses the monolithic shape of the building, and it avoids showing the two-sided space plan in the facade. The large glass lobby wall reveals a scenic view for the theatre's public facilities. This solution stresses the building's public role and its open access in an otherwise fairly closed row of buildings. In this way, the building finds its place in the continuum of autonomic theatre buildings. The basement floor of the building has been made out of reinforced concrete that was cast in-situ. The structural frame of the building is made of steel. The lobby section has been separated from the hall into its own structural entity for sound technical reasons. The structure consists of a high, reinforced concrete wall between the lobby and the hall, the steel beams that run parallel to the building's entry facade and support the upper and middle floors and finally, the steel support pillars. On the top floor, the 11 m section that exceeds the pillars has been executed as an overhang. The reinforced concrete shaft between the stairs and the lift operates as a reinforcer for the structure. The large scale glass wall is supported by the floor beams. In addition to the architectural themes I have been developing a model for a modifiable theatre hall, where the changes required by consecutive performances can he executed quickly and safely. The theatre hall type is a multi-use studio theatre. The size of the hall has been maximised in relation to the building mass in order to fit as large an audience as possible in the hall. Because of this, the hall does not have separate side stages or back stages. The measurements of the hall are: Length 35 m, width 21m, height 8.3 m (auditorium levels 1 and 2). The spaces required by theatre technology have been implemented on the conditions of modifiability. Traditional theatre hall lighting bridges and the stage tower have been replaced with a combination of a light and audio technical tier and a steel rail structured hoist tier. Because of this solution, the changes between performances can be executed very quickly and safely.
