Roof structure made of five hyperbolic paraboloid shells

The restaurant Ahornblatt stood in the Berlin district of Mitte in the Gertraudenstraße , corner Fischerinsel. The building was the social center for the Fischerinsel residential area , which was redesigned from 1970 to 1973 after the pre-war structure was almost completely demolished with six 21-storey high-rise buildings . In the building there was a self-service restaurant with 880 seats for the Ministry of Building of the GDR and for surrounding schools as well as a shopping mall.

Design and construction

On the initiative of the Politburo member Paul Verner , a modern shell structure from Ulrich Mueller's hand was to be built in the GDR capital Berlin . Even back then, civil engineer Müther was one of the leading specialists in shell construction with his company VEB Spezialbetonbau from Binz on Rügen . The architects Gerhard Lehmann and Rüdiger Plaethe were responsible for designing the infrastructure of the Ahornblatt , while the urban planning was carried out by Helmut Stingl. Müther gave the name maple leaf because of the maple leaf-like shape of its roof.

The roof structure was a shell construction of five hyperbolic paraboloid m per 22 × 35, which were arranged like a fan, recalled in appearance to a maple leaf and led to the naming of the building. The roof was only seven centimeters thick. The roof edges curved upwards towards the high points. At their lowest points, the roof segments supported themselves on conical supports made of reinforced concrete, which in turn were based on bored piles in the soft subsoil. The roofing consisted of a rebated roof skin made of aluminum. The outer walls were glazed and structured by horizontally arranged sun protection slats.

A shopping arcade and a 600 m² department store were connected to the kitchen wing of the restaurant .

The roof was built from September 1969 to December 1970. The entire construction of the two-story maple leaf was completed in 1973. In September 1995 the Berlin State Monuments Office placed the maple leaf and its ancillary buildings under monument protection. The Berlin state monument curator Jörg Haspel rated the maple leaf as an important “representative of› organic building ‹” and as a “revolutionary building certificate”. "The maple leaf embodies an architecture of hope in new constructive and creative possibilities of concrete shell construction ."

use

After its opening on July 18, 1973, the restaurant initially served as a restaurant for the participants in the Xth  World Festival . It was then used as a company restaurant for the employees of the surrounding companies and offices and for the construction workers of the Palace of the Republic . Around 1,000 children from nearby schools also had their lunch there. In the afternoons and evenings it served as a public restaurant and also for parties and events.

After the fall of the Wall , the CDU held its election party here on March 18, 1990 on the occasion of the first democratic people's chamber election in the GDR. After that, the building was used as a nightclub by an American company under the name Exit . From 1993 onwards, DJ Tanith organized regular after-hours evenings with “hard techno ”. Due to complaints from residents about increasing noise pollution, the discotheque had to be closed. From 1994 on, the maple leaf stood empty for six years.

demolition

In 1997, the Oberfinanzdirektion Berlin, with the support of the then Senator for Urban Development Peter Strieder and the former Senate Building Director Hans Stimmann, sold the site with the now listed building to Objekt Marketing GmbH . Despite numerous protests against the destruction of modern architecture in the GDR, including from the Berlin Chamber of Architects and the Deutscher Werkbund , the buyer of the site was given permission to demolish the maple leaf . Federal and Senate had previously years to sell their land for 29 million Deutsche Mark decided.

First, the architect of the new building, Gernot Nalbach, proposed a high-rise building with the same height as the surrounding high-rise buildings in order to save the maple leaf . The Berlin eaves height of 22 meters enforced by Stimmann , which was also included in the development and zoning plan for the inner city , now served the Senate Department for Urban Development as a means of rejecting Nalbach's high-rise despite the high-rise surroundings. In 1999, Nalbach finally presented an eight-storey roadside development with the desired 22 m height, but his plan required one lane from Gertraudenstrasse . The Senate Administration also rejected this proposal.

On January 21, 2000, Müther took one last tour of his building. On July 19, 2000 the demolition of the maple leaf began . In its place, the Accor Group built a middle-class hotel for business travelers and families clad with natural stone slabs, as well as an adjoining residential and commercial building.

Müther and his life's work came into the focus of a broad public for the first time in his life during the debate about the demolition of the maple leaf . Around 200 newspaper articles and short television reports were published. "The demolition of the maple leaf in Berlin got me out of my mind," he said afterwards. Since then, there has been an interest in Müther's “bold solitaires ”, the title of one of his first exhibitions.
