Zentralplatz, 재개발 프로젝트는 약 20,000 스퀘어 미터의 리테일과

도시기능을 수반하는 공간 그리고 6,000 스퀘어 미터의 광장으로 진행된다.

건축물은 각 프로그램의 기능에 따라 2개의 동으로 분리, 디자인되어

일반 보행자의 통과동선을 보장하는 동시에 건축물 내부로 유입시키는

출입동선을 적극적으로 유도한다.

공공도서관, 미텔라인 박물관 그리고 관광정보센터로 이루어진

컬쳐센터는 상이한 듯 닮은 문화공감대를 중앙광장을 중심하는 하는

컬쳐밴드로 시너지 효과를 만들어 낸다.

특히 광장의 중심부에 독립적으로 위치한 컬쳐센터는

위치가 갖고 있는 특성 및 심플하면서도 세련된 파사드 디자인으로

전체 프로젝트의 캐릭터를 형성하는

랜드마크가 된다.

여기에 세련된 파사드 디자인은 화이트 실크 스크린으로 이루어진

더블 스킨 구조로 내외부를 필터링 하는 동시에 전체 건축물의

이미지를 메이킹 하는 디자인 요소로 사용된다.

The project started as a won competition for the redevelopment of the “Zentralplatz”. The program included approximately 20.000 m² of retail space, urban functions and a 6.000 m² square

The complete program is split into two volumes, separated by the Zentralplatz. This separation of functions allows for two autonomous and highly functional buildings, which can develop long-term and independently. Because of the precise positioning of the buildings and their outline, the pedestrian flows are organized in an effective and logical way.

The Kulturbau houses the public library, the Mittelrhein Museum and the tourist information of Koblenz, with their ‘Zentrum der Rheinromantik’. The combination of these different cultural institutions offers the chance to exploit the synergies between the various institutions. The cultural building stands solitary in the new central square and is a landmark due to this solitary character, its facade design and the conscious elevation in the city. The building has splendid accessibility for visitors; the central lobby has entrances from all sides and is therefore a natural part of the urban fabric.

On the open square, the three functions each have their own entrance. Via prominent access elements like the spiral staircases (museum and tourist information) and the escalator (library), the institutions can be reached. Above the common ground floor area, the different functions overlap each other per floor. The permanent exhibition of the Mittelrhein Museum occupies the first floor. The library is located on floor two, four and five, with direct access to the roof terrace. The 30 meters high open space inside connects the institutions vertically, brings day light deep into the building and offers a variety of outlooks.

The volume has a double facade with a Structural-Glazing construction of white silk-screened glass, which envelops the building like a second skin and offers a frosted and refined appearance. The motif of the print provides a filtered view from inside to outside, and allows a vaguely transparent view when looking from the outside in. At the different entrances, the outer facade has a spacious cut and therefore offers a direct view of the lobby and entrance areas.

The mall Forum Mittelrhein presents itself as a flat, horizontally layered structure. Due to this powerful format, the building’s volume is reduced efficiently and a pleasant sense of scale is established. On relevant junctions within the urban fabric, the mall offers spacious entrances. The shopping center is characterized by its trapezoidal layout and smooth outlines. The areas intertwined with escalators offer orientation points, divide the building and provide the interior with natural light. Above the stores are adjoining rooms and a parking lot for about 740 cars. The parking spaces are organized around a central landscaped courtyard.

Together, the glass facade on the ground and first floor with standing formats, and the expressively shaped click frames, give a strong vertical orientation. The top three floors of the building are dominated by an artificial “Weinlaub facade” (wine leaf facade). The basis of the structure is an abstract image of a vine leaf, which is interpreted freely as a 3D-shape. The entire facade is composed out of only one type of element, that is produced in an industrial thermoforming process. Kulturbau, Koblenz Text about the design Benthem Crouwel
