Tampere Hall, Tampere
The project for extension and renovation of 1990’s Tampere Hall involved radical changes in the functions of this concert and congress centre. In the project, a 400-seat conference room, which can be divided in two, was constructed, along with a 230-seat studio-style auditorium and rehearsal premises for Tampere Philharmonic Orchestra and its musicians. Also, a new Moomin Museum was built.
Because of the tight schedule for the first stage of the project, the extension had to be light in structure while taking into account traffic noise in the area. In the design of the soundproofing, particular attention was paid to the positioning of the extension, which was built partly above and between existing structures, and to the main maintenance route, which passes underneath the building.
Cost: 12.6 million euros
Net internal area: 6,300 m²
Metso main library, Tampere
Built in 1986, Metso, the internationally renowned Tampere main library, is an important feature of the local cityscape. Because of its irregular shape, the library’s structures are varied, and each is unique. Back in 1978, the entry by architects Raili and Reima Pietilä won in a design competition arranged for the city’s new main library.
This building was renovated in four stages, the last of which was completed in 2017. In conjunction with the renovation, the library’s functions and acoustic properties were brought up to date and adapted to meet the needs of current activities. In addition, the basement space was converted to library use.
Cost: 11.5 million euros
Gross floor area: 11,160 m²
Completion: 1986, 2017
Turku City Theatre
The Turku City Theatre project involved renovation and extension. The most visible change brought by the extension was the addition of a three-storey stage at the back. The personnel premises were moved to a new location, and a kitchen was built. The workshop premises, which were in need of work, were renovated and extended, along with the spaces for technical systems, the prop area, and the costume and scene shop. A new space was built for the Sopukka stage, which had to be moved to make way for the Pikkolo stage. In addition, the dressing rooms for actors were refurbished.
Cost: 45 million euros
Gross floor area: 14,525 m², volume: 76,467 m³
Hatanpää Manor, Tampere
In the course of its history, Hatanpää Manor has served as a military hospital, museum, and event venue. The manor’s main building is of architectural value and therefore is under protection in the city plan. Repair measures for the façade’s plastering, balcony structures, and gypsum ornaments were determined on the basis of a building survey with the aim of preserving as much of the old structures as possible. The old plastering was preserved to the greatest extent possible.
Cost: 1 million euros
Gross floor area: 2,100 m²
Designed by the Swedish architect Johan Erik Stenberg, the Neo-Renaissance Pori Theatre was built in 1884. The building underwent renovation between 2015 and 2017, in which all of the theatre’s technical systems were updated. In terms of structural engineering, the design of the support structures for the technical systems and the integration of systems presented the main challenges. The most demanding design project involved the steel trusses that were installed on the main stage’s tower, next to the old wooden trusses. All of the stage’s technical systems are supported by the new trusses. The original, wooden trusses, which are under heritage protection, now only support the roofing.
The theatre’s additional building, which houses the smaller stage and auxiliary facilities, was completed in 1974.
Cost: 15 million euros
Floor area: 5,500 m²
Housing company As. Oy Pohjolanpiha, Tampere
Built in 1981, the Pohjolanpiha property is a seven-storey residential building with washed concrete surfaces. The ground floor houses a day-care centre. In the project, the façade was renovated and the building’s appearance was modernised. Further insulation and thin-coat plaster were added for the façades of the residential floors. On the ground level, the surfaces were treated and repaired where necessary. In addition, balconies were renovated and equipped with glazing. Entrance doors were replaced, and new roofs were built.
Cost: 1.2 million euros
Floor area: 3,000 m²
As. Oy Tampereen Kauppakatu 14
The property at Kauppakatu 14 was built in two stages in 1902–1903 (the outer parts) and in 1926 (the middle). It was designed by architect’s office Geselius–Lindgren–Saarinen and architect Birger Federley. With regard to the façade, the goal was to use a colour that was as close to the original tone as possible as indicated by the old layers of paint discovered on the façade and ornaments. The façade’s plastering was redone in most areas, and the ornaments were refreshed. The windows, which had been replaced in the 1990s, were painted.
Cost: 1 million euros
Gross floor area: 6,000 m²
Housing company As. Oy Tasanko, Hämeentie 28, Helsinki
A three-year project was undertaken for the renovation of an Art Nouveau building in the Kallio district of Helsinki that originally was completed in 1912. In connection with the project, the building’s façade and plumbing were renovated, lifts and yard areas were refurbished, and new loft-style flats (with a total floor area of 860 m²) were built.
The design work and integration of various entities presented challenges at the realisation stage. Special attention had to be given to the lowering of the basement floor and related details.
In the construction of the loft-style flats, structural engineering expertise was particularly useful at the work-site stage. For the steel structures in the loft, product compliance was verified with a work-site-specific expert statement.
Cost: 9 million euros
SAMK campus, Pori
The campus of the Satakunta University of Applied Sciences (SAMK) in Pori is made up of a new building and a renovated one. This complex houses modern teaching premises, including open learning environments and laboratory spaces.
Because the entirety of the new building serves as a learning environment, particular attention was paid to architectural acoustics and measures for preventing noise from spreading. This building also features a multipurpose hall used for sporting and other events.
