The Lörrach town hall is a seventeen-storey administration high-rise built from 1972 to 1976 in the Lörrach city ​​center and is now a monument . The building with a dark green facade designed by the architect Thomas Heiß is the tallest building in the Lörrach district and the tallest town hall in Baden-Württemberg at just under 72 meters . In addition to the municipal offices, the town hall also houses the official residence of the Lord Mayor of Lörrach and the city archive.

history

prehistory

The Villa Favre at Turmstrasse 45, which was used as the town hall from August 5, 1927, did not offer enough space for all municipal offices in the 1930s, so that in 1934 the city building office, welfare and youth welfare office, land registry and surveying office were converted into factory premises had to move across from the train station. Plans for an extension in the garden of the villa failed due to lack of money and the outbreak of World War II worsened the situation. In 1955 the discussion about the lack of space was held again and another ten years later the municipal authorities were distributed at five different locations in Lörrach.

planning

The local council took up the problem more vigorously this time and initially spoke out in favor of a new building at the previous location of Villa Favre. A building commission visited a total of 13 town halls in Germany and one in Switzerland from December 1967 to May 1968 and on July 18, 1968 approved the implementation of an architectural competition . The jury, chaired by the well-known architect Egon Eiermann , selected the work of the Freiburg architect Thomas Heiss from a total of 72 models and planning documents submitted on June 10, 1969. The award-winning design was recommended for implementation by the local council on November 13, 1969, and he was commissioned to prepare planning for construction.

construction

After the municipal council had approved the cost estimate of 23,230,000 DM in March 1971 , the groundbreaking ceremony took place on March 21, 1972. The topping-out ceremony was celebrated on June 21, 1974 and the offices were able to move into the new building in January 1976. On the weekend of June 12th and 13th, 1976, the completion of the town hall was celebrated with a big festival on the town hall square. At the same time, the population was able to visit the new house as part of the open house. With a total cost of around DM 23.7 million, the construction increased by around DM 500,000. Since the new building fell during the term of office of the then Lord Mayor Egon Hugenschmidt , who also supported the construction, the building is also nicknamed “Langer Egon ".

Since construction

In November 2006, the town hall in Lörrach hit the headlines when a group of young people encouraged a young woman who wanted to throw herself off the roof of the skyscraper. The intervention of the police calmed the heated situation and dissuaded the woman from her plan.

The town hall was placed under monument protection at the end of 2012 as a "unique document of the 1970s architectural style" .

In 2018, in a test procedure lasting several months, a structural engineering office found that the enamelled facade panels of the Lörrach town hall were showing significant wear. These panels are fastened with screws and dowels in the corner areas. Since the substructure is also affected, the windowless facade surfaces must also be secured with nets. These deficiencies not only have an energetic effect, but also have an impact on road safety . In addition to the facade, the safety staircase must also be dismantled. A total of 3.5 million euros is budgeted for the extensive town hall renovation by 2021. According to a preliminary draft plan in 2019, the renovation should start in 2020. At the beginning of 2020 it was announced that no date could be presented for a possible start of the work. The project was thus postponed. In the meantime there are even plans to completely demolish the building.

On the morning of June 30, 2020, the throwing of an initially unknown white powder into the mailbox of the town hall triggered a large-scale fire brigade with 70 emergency services and 20 vehicles after three employees in the post office complained of eye and respiratory irritation. The powder later turned out to be harmless; it was calcium carbonate . The use and cleaning after the evacuation led to the town hall being closed all day.

Location and description

Urban significance

Town hall with town hall square seen from the east

The Lörrach town hall is located near the main train station and the main post office on the northeastern branch of the pedestrian zone. In the course of its new building, a new pedestrian area between the post office and the train station was opened to the east of the main post office, which has now almost completely grown together with the new inner-city pedestrian zone. The city's central bus station is located north of the town hall .

The town hall square east of the town hall is slightly lowered to the rest of the street level. The square, paved with natural stones, where flea markets or other events often take place, is lined with partly old trees. The granite sculpture Triad by the artist Giancarlo Sangregorios is located on the square and forms a station on the Lörrach Sculpture Trail.

South of the town hall on the footpath to the nearby Bonifatiuskirche stands a small fountain of life in the form of a fruit, designed by Jörg Bollin . The 72 meter high structure forms a dominant feature of urban development and can be easily recognized both within the city and from many of the hills of the lower Wiesental . The dark green color of the facade should adapt to the wooded area of ​​the Lörrach area.

Architecture and structure

Base building that houses the council chamber

The Lörrach town hall is roughly divided into two externally visible areas: the entrance and hall area in the form of a cantilevered, 11-meter-high base structure and the administration area in the adjoining office tower.

Through the main portal in the east from Rathausplatz - another entrance in the north was closed in favor of the citizen's service office - one arrives at the foyer , which is sometimes also used as an exhibition hall. The council chamber, two conference rooms connected by a sliding wall, parliamentary group rooms and a lounge are located on the first floor. The floors on the ground floor are made of marble, the ceilings of exposed concrete . In the plenary area, the floor is partially covered with carpet; Ceilings and walls are made of rough plaster or exposed concrete.

Above this is the administrative area, which is combined into two or three-story units depending on the size of the offices. These are connected to one another via internal connecting stairs and the centrally located elevator. A color guide system serves as an orientation aid for the individual offices and their accommodation on the units in the building, some of which span floors. For this purpose, the inner walls with colored enameled steel panels lined. The floors are lined with carpets and office areas can be designed variably using adjustable partition walls.

The technical service with telephone system and print shop is located on the second floor. The 11th floor with offices for the mayor, the mayor and their employees as well as the 13th floor with the lounge are special floors, which can be distinguished from the outside by incisions in the facade. The 57.7 meters roof terrace, which is only accessible to the public as part of guided tours, is followed by the superstructures for the elevator machine and the ventilation rooms. This obscures the view to the southwest. In addition to the connecting stairs in the corridor area and the elevators in the core area, there is also a separate emergency staircase that completely runs through the western part of the building.

In addition to the building services, the warehouse and the city archive are housed on the two underground floors. A two-story underground car park for 197 parking spaces is also located underground in a separate building .

Technology and safety equipment

Aerial view from the east

The town hall tower is supported by a reinforced concrete skeleton and two supply shafts. The middle core houses an elevator system with three cabins for six people each and one cab for twelve people. For rational reasons, the elevators are maneuvered using a group control. The elevator shaft has a lifting height of 71 meters. The maximum travel speed is 3 meters per second. The lift system's technical rooms are on the 18th floor. A panorama webcam has also been housed on the top floor since August 2019, which not only offers a current panoramic view, but also an archive of previous recordings and a time-lapse function.

The high-rise is heated by a two-circuit boiler system with heat transfer for water and steam. The pipeline system of the natural gas- operated system is located in the core of the building and can be divided into four separately controllable height zones and two weather groups.

The town hall is ventilated via an air conditioning system in the base and via freely adjustable vertical sliding windows in the office tower. The air inlet takes place mechanically via the corridor area, the exhaust air is extracted via the toilet system. The underground car park is supplied via a separate ventilation system. The total output of the ventilation systems is 92,000 cubic meters per hour.

The power supply in the house is guaranteed by a transformer (630 kVA ) on the technical floor. In an emergency, the town hall can be supplied with a diesel generator via an emergency power system. A photovoltaic system with a maximum output of 4.9 kilowatts peak , which was installed on the roof of the council chamber, has been connected to the grid since August 2011 .

Ten directional radio antennas are also attached to the town hall , which are used for voice and data exchange with urban branch offices such as local administrations or the adult education center. An analog radio antenna also enables voice contact with all vehicles in the depot in the city.
