Project description

Reason for planning
“South of Rödelheimer Landstrasse” is a prime location in the City of Frankfurt. The site is defined by a mixture of high-quality commercial outlets and brownfield sites, businesses in the immediate vicinity of existing residential buildings on Rödelheimer Landstrasse, as well as vacant premises. In particular the aspect of “local development” urgently calls for rezoning of the site.

With a view to redeveloping the zone south of Rödelheimer Landstrasse plans were made as early as 2009 for the statutory planning requirements for a modern commercial district complete with office and residential buildings. To this end, zoning maps were developed ready for public disclosure.

Due to conflicts under planning permission law, and these could not be resolved, the plans for the zone have now been adapted. Consequently, the procedural step of public disclosure needs to be repeated. Of special relevance here is the necessary relocation of companies, whose location within the zone to be developed have thus far thwarted development as previously planned; the outcome is not yet foreseeable. In the 2009 urban design proposal several existing companies were on sites now designated for residential homes, public green spaces and roads, meaning that the realization of the plans hinged on relocating said firms. Moreover, Siemens AG reconsidered its plans for the future use of the premises. The company now intends to in the medium term relocate all units it has in this area and therefore no longer opposes the zone being dedicated to residential development.

These fundamental changes to the overall conditions call for a revision of the existing plans and the adoption of new planning approaches.

Development district
The site in question is bounded by the Main/Weser rail track in the east, Rödelheimer Landstrasse in the north, Ludwig Landmann Strasse in the west, and the Frankfurt-West – Frankfurt/Rödelheim LRT line in the south. In the south, an area from the City-West complex has been included in the scope of planning to facilitate a decision on the construction of an underpass beneath the LRT tracks.

The geographical scope of development plan no. 834 – South of Rödelheimer Landstrasse covers an area of some 28.5 hectares.

Planning objectives
The draft design envisages a concept that will reflect the needs of those established companies which are unable to relocate in the foreseeable future by including them in the replanning as far as possible. Individual businesses situated on Rödelheimer Landstrasse play a decisive role. Odor emissions from Burka Kosmos, a company that makes grinding disks, have to be taken into consideration, along with above-average noise emissions from two freight companies.

The focus will be on planning and developing a self-contained urban mixed-use quarter complete with residential buildings, service outlets, commercial structures and accompanying facilities. In a move to connect the district to other downtown quarters the intention is to augment infrastructural links to the adjacent neighborhoods. The incentive here is to hook the zone up to Ludwig Landmann Strasse and to City West south of the railroad tracks.

Project progress
The project got underway in 2003 on the back of intentions by Siemens to build in the zone in question. Subsequently the Siemens Group abandoned its plans, thus necessitating modification of the urban planning objectives. However, despite the withdrawal of a major investor, the intention was for planning to go ahead. Developments already initiated in the zone called for meaningful urban planning regulations, while property owners and users needed a sound and reliable basis for planning going forward.

The return to the drawing board provided an opportunity to rethink the zone’s development potential in the context of changed economic conditions. Among other things, the focus shifted in favor of increasing the proportion of residential units in the district.

Two planning firms were commissioned to develop new concepts for the area. The City selected the design proposed by Berlin-based Planungsgruppe 4 for further elaboration as part of the planning process, and it was revised accordingly.

The new plans were presented to the Consultative Local Council in October 2006. Several information sessions were then held to give local citizens the opportunity to discuss the impact of and opportunities provided by the planning.

The development plan was made available for public inspection from July 29, 2009 to September 11, 2009. The plan is currently being revised on the basis of numerous statements and suggestions that were thereupon received.

At the same time, the City Planning Department has been in regular consultation with the companies concerned. The City has now succeeded for the first time in developing a feasible basis for relocation with a company willing to do so and in relation to this evolve new opportunities for development at a different location within the city limits.

However, the parties involved were unable to solve the legal issues in relation to planning permission. In 2013, Berlin-based Planungsgruppe 4 joined forces with Frankfurt’s City Planning Department to develop a new urban design concept.

The design concept together with a proposal for potential future development and the structural concept (which lays the basis for the development plan to be established) are available as downloads (see below) and illustrated in detail on the following pages.

The property owner and the companies under the ambit of the plans have already been involved in the procedure and informed about the objectives and potential progress in the planning procedure in a number of meetings.

The concept was presented to the public as part of the meeting of Local Consultative Council no. 7 on February 25, 2014.

The City Council passed the amendment to the resolution on May 22, 2014.

The application made by the Municipal Authorities (M250 2013) was approved, with the proviso that

“(a) the Municipal Authorities shall, if necessary, consider more recent interests by property owners in residential construction that may also extend beyond the zoning plan, provided that this is compatible with the continued operation of existing businesses located within the commercial sections as designated in the zoning plan, and

(b) as regards the entire development district the Municipal Authorities shall evaluate whether a balance of mixed and residential areas and suitable noise protection may help curb potential conflicts between existing businesses and new residential developments that are moving closer, with special emphasis on noise emissions.”

The development plan proposal is currently on the drawing board, with special attention accorded to the steps illustrated above.

Frankfurt currently has an enormous need for more housing. According to the latest predictions given in the population and household forecast of the Municipal Statistics and Elections Office (as at June 2015), the number of inhabitants will rise to 810,000 by 2030, and to 840,000 by 2040. Based on this forecast, in June 2016 Institut Wohnen und Umwelt GmbH (IWU) complied a forecast of the volume of housing needed. According to it, by 2030 an additional 90,000 residential units will be needed, and by 2040 an additional 106,000. The plan is to cover this requirement by creating attractive housing: The land south of Rödelheimer Landstrasse can play an important role in this regard.

 

 

Development area


The development area is bordered by the Main/Weser rail track in the east, Rödelheimer Landstrasse in the north, Ludwig Landmann Strasse in the west, and the Frankfurt-West – Frankfurt/Rödelheim LRT line in the south. In the south, an area from the City-West construction site has been included in the scope of planning so as to facilitate a decision on the construction of an underpass beneath the LRT tracks.

The geographical scope of legal zoning plan no. 834 – South of Rödelheimer Landstrasse covers an area of some 28.5 hectares.

 

Planning objectives


The objective behind the proposed design is to provide a concept for the development of a spacious residential area. Ii also takes into consideration businesses which cannot be relocated in the foreseeable future and integrates them in the new plans. Individual businesses on Morsestrasse are of greater significance.

With this restructuring of the facilities, and taking into account the distinctive circumstances, i.e., the contradictory interests and intentions of different players, conflicts on noise emissions will be taken into consideration and to a large extent diminished. This will be possible thanks to detailed knowledge of the emissions levels of the various businesses. On the back of the noise assessments conducted, the results can as a rule be reconciled with the degree of disturbance permitted by planning legislation in mixed-use areas and as such lead to a different outcome than if some generalization is taken based on a standardized view of the businesses. At the same time existing facilities will be strengthened. The remaining commercial area will be stabilized, specifically through improved access, and clarification of development objectives drawn up in line with planning legislation. The change of the categorization of the area as “an industrial zone not appropriate for the area” to “Urban Areas” will provide businesses and landowners with greater certainty for their planning.

Through the designation of new land for housing construction and the additional designation of parkland and land for additional facilities, existing housing inside and outside the development area will be amalgamated. By pooling the housing in this way, for the first time a scale will be achieved that makes it worthwhile establishing the requisite additional facilities such as food retailers, nurseries, and in particular an elementary school. This ensures a great level of high-quality living.

To foster connections within the urban fabric, the intention is to forge links to neighboring quarters. The area will be connected to Ludwig Landmann Strasse and City West south of the railroad tracks. Public access in particular needs improving – as regards the link to City West (a planned underpass), which is currently inadequate to allow further development of the area. Within the geographical scope of the project the planned underpass will impact negatively on the plots of land to the south of the LRT tracks, in particular with regard to access to them. The restructuring of these areas and the stipulation of contiguous building structures takes this situation into account.

The objective of the City of Frankfurt/Main (application M 9 by the city executive dated January 17, 2014 – resolution of the City Council dated May 22, 2014 section 4542), to earmark, inasmuch as the legal conditions are in place, 30% of the new gross surface area made available for subsidized housing, will be observed.

Project progress


2002
When the project got under way in 2002 Siemens harbored plans to build on the site. When the Siemens Group abandoned its scheme, the urban planning objectives were modified. Despite the withdrawal of a major investor, planning continued.

The development measures begun in the area needed a meaningful urban development structure. Landowners and users required a sound basis for planning going forward. The return to the drawing board also provided an opportunity to rethink the zone’s development potential in the context of changed business conditions. This also including increasing the proportion of residential units. Two planning firms were commissioned to develop new concepts for the area. The City selected the design by Berlin-based Planungsgruppe 4 for further elaboration as part of the planning process, and revised it accordingly.

2006
The new plans were presented to the Local Consultative Council in October 2006. Several information sessions were then held to give local citizens the opportunity to discuss the impact of and opportunities provided by the planning.

2009 - 2012
The plan was made available for public inspection from July 29, 2009 to September 11, 2009.

The plan was revised on the back of the large number of opinions and suggestions submitted. At the same time, the City Planning Department was in regular consultation with the companies concerned. The City succeeded in developing a feasible basis for relocation with a company willing to do so and in relation to this evolve new opportunities for development at a different location within the city limits.

2013 - today
The parties involved were nonetheless unable to solve the legal issues relating to planning permission. In 2013, Berlin-based Planungsgruppe 4 joined forces with Frankfurt’s City Planning Department to develop a new urban design concept.
In 2014 this concept formed the basis of an amendment to the resolution, which the City Council adopted on May 22, 2014.

In the further course of the project a large section of the development area, the former Siemens site, was sold to Nassauische Heimstätte and Instone Real Estate. At the same time, several businesses in the development area expressed a wish to relocate. Located at the heart of the quarter, the grinding disc manufacturer Burka Kosmos ceased operations. Overall, these fundamental changes to the framework conditions led to the renewed revision of the urban development approach. The current design is the basis of the draft of the legal zoning plan.

Nassauische Heimstätte and Instone Real Estate are calling their part of the development area “Schönhofviertel”.

The other landowners and businesses in the geographical scope of the project were involved in the procedure and, in numerous discussions, informed of the objectives and the possible course of the planning procedure.

A land consolidation procedure is required for the full implementation of the legal zoning plan. On the back of a resolution adopted by the City Council on August 31, 2017, section 1689, redistribution in accordance with sections 45 ff. of the German Building Code (BauGB) has already been decreed. The hearing with the landowners and lease holders has already taken place. The consolidation procedure will be initiated soon.
The draft of the legal zoning plan is currently being prepared for public display.

The result of the closed realization competition for the center of the quarter will be announced shortly and will be presented here.

Urban design proposal

The urban design proposal in question illustrates feasible exemplary structures that will be required in the development zone in the future.

The development zone hinges on a mix of predominantly residential units with auxiliary service outlets and central facilities, including commercial sections and defining green areas. The key design element here is the central band composed of public green spaces and social infrastructure. The zones to the north and south of it are earmarked for well-designed residential quarters with car-free courtyards. The central urban band not only links these quarters with one another, but is also connected to the local amenities. The large retail area is conveniently located in the center of the zone, on the corner of Rödelheimer Landstrasse with Birkenweg, meaning that it can also serve the surrounding districts. The closed structure of the apartment building on the eastern edge of the ambit shields the zone from the rail tracks. The concept of residential quarters that are accessed via cul-de-sacs is continued westwards along Rödelheimer Landstrasse, until it culminates in a new road that links Rödelheimer Landstrasse with Morsestrasse. Closed structures extending along Ludwig Landmann Strasse complete the development zone in the west.

The previous objectives for commercial section A in the southwest will essentially be retained, meaning that the existing companies in this zone will be integrated into the planning. Moreover, the existing companies in sections B and C will be included as pre-defined zones in the planning. The thoroughfares on Morsestrasse will be retained and extended; its transport links with Ludwig Landmann Strasse are considered absolutely necessary.

The course of the road with the planned “Birkenweg - An der Dammheide” underpass departs from the old proposal. Now the route extends parallel to the property of the Burka Kosmos commercial business (eastern section B). Most of the planning for the sections south of the rail tracks will be retained, with only slight modifications as a result of changes made to the spatial layout of the underpass.

In a move to enable efficient access to the zone, Kasernenstrasse, which currently extends along the eastern fringe of the development zone, will be shifted west by the width of a single building plot, where it will border the zone’s transport infrastructure.

The intention is to keep building heights uniform in line with the previous urban design proposal. Accordingly, the majority of buildings located on the roads will be five stories high, while those overlooking open spaces and the internal infrastructure will have mostly three and four stories. Only along Ludwig Landmann Strasse do plans envisage taller structures in harmony with the existing high-rise.

Blockrand prägt Plangebiet
Prägende Struktur im gesamten Plangebiet ist der Blockrand. Die städtebauliche Gruppierung von Gebäuden in geschlossener Bauweise um einen gemeinsamen Hof wird zu Zwecken der sinnvollen Segmentierung und der Erschließung entlang der Straßen teilweise aufgebrochen. Liegen die Blockränder unmittelbar an öffentlichen Grünflächen, öffnen sich die Blockstrukturen zu einer Zeilenstruktur. Hier öff-nen sich die Blockränder und ermöglichen so eine Vernetzung des privaten und öffentlichen Freiraums sowie Blickbeziehungen in die Freiflächen.

Abwechslungsreiche Gebäudetopographie durch gestaffelte Geschosshöhe
Die gestaffelte Höhenentwicklung der Gebäude von fünf bis acht Geschossen reagiert auf die umliegende Bebauung. Sie schafft eine auf den Standort bezogene abwechslungsreiche Gebäudetopographie und orientiert sich an dem Leitbild eines durchgrünten und verdichteten Stadtquartiers in hervorragender Lage.
Das städtebauliche Erscheinungsbild ist im Wesentlichen von einer durchschnittlich sechsgeschossigen Bebauung geprägt. Deren Dichte ist durch die zentrale Lage und die Größe der öffentlichen Grünflächen gerechtfertigt. Zur Vermeidung eines zu homogen-monotonen Straßenbildes werden Akzente mit Hochpunkten bis zur sogenannten Hochhausgrenze (Gebäude, bei denen der Fußboden mindestens eines Aufenthaltsraumes mehr als 22 Meter über der festgelegten Geländeoberfläche liegt) gesetzt.

Gestaltungselement der Quartiersmitte – „Die Spange“
Wesentliches Gestaltungselement ist das zentrale grüne Band. Es besteht aus zwei großzügigen öffentlichen Grünflächen sowie, je nach Ausgestaltung der Quartiersmitte, dem zentralen öffentlichen Platz.
Die Quartiersmitte - die sogenannte „Spange“ - beschreibt den Quartiersplatz sowie multifunktionale Gebäude mit öffentlichen und infrastrukturellen Nutzungen.
Die „Spange“ bildet, neben dem öffentlichen Grünzug, das städtebauliche Rückgrat des Quartiers. Damit verbindet das Gebäudeensemble die Wohnquartiere im Osten und im Westen. Somit kommt der „Spange“ auch in städtebaulicher und architektonischer Hinsicht eine herausragende und gestaltprägende Bedeutung für die Adressbildung des Quartiers zu.
Aufgrund der hohen Bedeutung für das Gesamtgebiet sollte die detaillierte Klärung der Spange und ihrer städtebaulichen Ausformung in einem Wettbewerbsverfahren geklärt werden.
 
Quartiersplatz mit hoher Aufenthaltsqualität
Der Quartiersplatz soll einen attraktiven Verweilort darstellen. Er soll den Bewohnern des Quartiers in der Funktion als Quartiersmitte als Treffpunkt und räumliche Mitte dienen. Unter Berücksichtigung der verschiedenen Nutzungen (zentraler Zugang zur Grundschule, zum Einzelhandel, u.a.) soll er dabei eine hohe Aufenthaltsqualität bieten.

Öffentliche Grünflächen
Die öffentlichen Grünflächen im zentralen Teil des Plangebiets dienen der planungsrechtlichen Sicherung zur Anlage eines Bürgerparks. Dieser soll einer vielfältigen Erholungs- und Freizeitnutzung zugänglich sein. Seine Größe beträgt etwa 2,1 ha. Es ist eine Parkanlage mit vielfältigem Charakter vorgesehen. Sie steht im Bezug zur umgebenden Bebauung und wird den Nutzungsansprüchen der Anwohner und Beschäftigten gerecht. Bestandteile der Grünfläche stehen demnach als untergeordnet Spielflächen für unterschiedliche Altersgruppen sowie Flächen zum Ausruhen und Verweilen zur Verfügung. Über Fuß- und Radwege ist die Grünfläche mit der Umgebung vernetzt. Darüber hinaus können Pausen- und Sportflächen der im Sondergebiet „Quartiersmitte“ geplanten Grundschule dort angeordnet werden.

Erhöhte Randbebauung am östlichen Ende des Parks
Das östliche Ende des Parks wird durch einen differenzierten hofartigen Gebäudekomplex mit einer zur Main-Weser-Bahnlinie erhöhten Randbebauung und einer innenliegender Gebäudegruppe geprägt.

Entwicklung gemischter Strukturen im Westen
Im Westen steht die Entwicklung gemischter Strukturen bei Bestandssicherung der vor Ort verbleibenden Betriebe im Vordergrund. Bauliche Erweiterungen sollen vor allem straßenbegleitend stattfinden. So können in den Innenbereichen die gewerblichen Nutzungen, wenn möglich, ohne Einschränkungen fortgesetzt werden. Weiterhin bleiben großflächigere Bebauungsmöglichkeiten für die Betriebe innerhalb der Baufelder möglich. Eine geschlossene, straßenbegleitende Bebauung schließt das Plangebiet nach Westen zur Ludwig-Landmann-Straße ab.

Straßenbegleitende Bebauung südlich der S-Bahn-Trasse
Südlich der S-Bahn-Trasse wird unter Einbindung der Bestandswohngebäude Ecke Solmsstraße / Verlängerung An der Dammheide die Systematik der straßenbegleitenden Bebauung aufgenommen.


Soziale Infrastruktur und Nahversorgung

Kindertageseinrichtungen
Bei einer Anzahl von insgesamt circa 2.500 neuen Wohneinheiten im Gebiet werden umgerechnet circa 12 Gruppen für die Betreuung von unter dreijährigen und 16 Gruppen für Kinder im Kindergartenalter (drei bis sechs Jahre) benötigt. Hierzu werden insgesamt sechs Kindertagesstätten mit jeweils zugeordneter Freifläche in die neue Wohnbebauung integriert.
Es soll sich bei den Kitas jeweils um in einen Gebäudekomplex eingeschobene Einrichtungen handeln. Sie werden jeweils in der Größenordnung der Geschossfläche der Hauptnutzung untergeordnet. Aus diesem Grund werden die Kitas nicht exakt lokalisiert festgesetzt, sondern nur deren Größenordnung im jeweiligen Baugebiet. Hierdurch soll die Freiheit gegeben sein, in der Entwurfsfindung des Hochbaus die Kita je nach Konzept passend einzufügen und die Freibereiche entsprechend zu verorten.

Grundschule
Aus den neu geplanten Wohneinheiten errechnet sich die Zahl von 94 zusätzlichen Schülerinnen und Schülern pro Jahrgang. Die Zahl ist ein rechnerischer Näherungswert, der im Endergebnis vom tatsächlichen Mischungsverhältnis von Wohnnutzungen zu gewerblichen Nutzungen in den „Urbanen Gebieten“ abhängig ist.
Darüber hinaus sind deutlich steigende Schülerzahlen in den benachbarten Grundschulbezirken dokumentiert. Ein deutlich erhöhter Bedarf an Grundschulplätzen wird somit ausgelöst. Am Grundschulzweig der im Umfeld bestehenden Georg-Büchner-Schule können diese Schülerinnen und Schüler nicht aufgenommen werden, da die Aufnahmekapazität des Grundschulzweigs der Georg-Büchner-Schule bereits ausgeschöpft ist. Daher besteht der Bedarf für eine weitere Grundschule im Siedlungsgebiet.
Eine vierzügige Grundschule soll zentral im Gebiet untergebracht werden und bereits in einem der ersten Bauabschnitte realisiert werden können. Die Schule liegt in der Quartiersmitte, welche als bauliche „Spange“ die westlichen und östlichen Quartiersbereiche verbindet.
Die Grundschule ist in einem städtisch geprägten Gebäudeblock integriert. Das tradierte Bild einer freistehenden Schule mit eingezäuntem Freigelände entwickelt sich zu einer Schule als Baustein intensiven öffentlichen Lebens in einem nutzungsgemischten Block.
Das Gebäudeensemble soll neben der Bildungseinrichtung auch Wohnungen beinhalten. Mit der "Hybridschule" erfolgt Lernen und Wohnen unmittelbar nebeneinander und/oder übereinander. Weil in einem solchen komplexen Modell vielfältige Wechselwirkungen zum Tragen kommen – mit Erweiterungen und Beschränkungen – gilt es zwischen Öffnung, Verschränkung und Schutzbedürfnis die Nutzungsbedarfe der Schule frühzeitig präzise zu definieren.
Zur Vorbereitung des neuen Grundschulstandorts hat ein Planungsprozess für leistungsfähige Schulbauprojekte im Primärbereich, die mit Investoren umgesetzt werden sollen, stattgefunden.
Im Zuge dieser Entwicklungsplanung, der Phase Null, wurden im Laufe des Jahres 2018 für das künftige Gebäude der neuen Grundschule im Plangebiet alle grundlegenden Kriterien und Anforderungen formuliert. Eingebunden in die Gesamtdebatte zum Planungsrahmen Grundschulen Frankfurt am Main konnten gemeinsam mit Vertreter/innen aus Schulen, Verwaltung, Projektentwicklung, Eltern- und Schülerschaft die Eckpunkte für einen schulischen Neubau in einem verdichteten innerstädtischen Gebiet präzise definiert werden. Die Ergebnisse formulieren an der Schnittstelle zwischen Pädagogik und Raum belastbare quantitative und qualitative Maßgaben für die weitere Planung. Die Ergebnisse waren außerdem Bestandteil des nichtoffenen Realisierungswettbewerbs Neubau zweier nutzungsgemischter Gebäudekomplexe sowie städtebauliche Ideen für einen Quartiersplatz.

Nahversorgung
Da das Gebiet bisher gewerblich genutzt wurde, sind keine Nahversorgungsstrukturen etabliert, abgesehen von den Großhandelsbetrieben, die auch an Endverbraucher verkaufen. Auch umliegend befinden sich Wohnlagen, die weiter als 600 Meter (angenommene Fußläufigkeit) vom nächsten Supermarkt entfernt sind, namentlich die Postsiedlung im Westen, die Bebauung nördlich der Rödelheimer Landstraße sowie der südliche Teil des Industriehofs.
Zur wohnungsnahen Grundversorgung dieser Bevölkerung ist im Plangebiet ein Nahversorgungsstandort vorgesehen. Er befindet sich in zentraler Lage mit Orientierung zum Quartiersplatz und dient somit auch der Belebung des Quartiers. Rechnerisch kann dieser Standort mit der geplanten Verbindung zur City West auch weitere Kundenpotenziale in fußläufiger Distanz erschließen.


Competition results: Center of the quarter

Object of the tender

The tender focused on planning for the future center of the quarter. Across a total of some 45,000 square meters of gross surface area, it brings together the total of about 2,500 apartments that make up the quarter in its east and west sections. The center of the quarter will function as a meeting point for residents and as its spatial heart. With the two buildings and the plaza between them as the center, it also acts as the urban planning spine for the planning area covered by Südlich Rödelheimer Landstrasse.

Nassauische Heimstätte is responsible for the construction work on the site to the south of the central plaza and is entering virgin territory in this regard. Here, together with the City of Frankfurt, Hessen’s largest housing company is realizing Germany’s first horizontally mixed hybrid school.

Looking back: The intention was to integrate the primary school into a block of buildings with an urban flair. The traditional idea of a standalone school with grounds surrounded by a fence thus morphed into that of a school as a module for intense urban life in a mixed-use block. The plan was to create an ensemble of buildings that featured not only the primary school but also included apartments. The “hybrid school” thus enabled learning and living directly next to each other or the one over the other.

To prepare the site for the new primary school, a planning process first took place concentrating on viable building projects for primary schools that could be realized with the involvement of investors.

In the course of this development planning (Phase Zero), during 2018 all the fundamental criteria, requirements, and standards were drawn up for the future construction of the new primary school in the planning zone.

The project was part of the overall debate on the framework for planning primary schools in Frankfurt, as initiated by the Municipal Dept. of Schools. In the context of that process, representatives of schools, the administration, parents and pupils defined the key design parameters for new-build schools for downtown areas where space is limited. The results make a strong contribution towards bringing teaching and spatial planning requirements into line with each other and ensuring they are met. Moreover, these formed the basic conditions in the closed competition for the realization of new builds for two mixed-use building complexes as well as urban planning ideas for a central plaza for the quarter.

In their winning design, Ackermann + Raff draw their inspiration from school buildings in Holland and Scandinavia, and opt for a structure based on a perimeter block with the functional zones “stacked” around a central inner courtyard. Cavities and projections give rise to sections that serve as internal free areas and as interfaces to the public space. The lion’s share of the apartments on the site will receive public subsidies and be as energy-efficient as possible.

The building north of the central plaza, to be realized by Instone Real Estate, will contain all the local facilities for the new quarter: two supermarkets, several retail stores, and hospitality outlets facing the plaza. On the first floor, there will be medical practices or offices and an indoor childcare facility. The remaining areas and all the other stories will be reserved for apartments. In their proposal, Menges Scheffler Architekten took their cue from the idea of a perimeter block as the basic fabric for hybrid usages. The different building heights respond to future surrounding buildings. The apartment section, with the different building depths, provides a clear-cut structure for the ensemble. Here, too, some of the apartments will benefit from public subsidies.


Retail, childcare and housing. On behalf of Instone Real Estate, Frankfurt-based Menges Scheffler Architekten have designed the structures for Site B, north of the central plaza. Rendering: Menges Scheffler Architekten.

Instone Real Estate wird in dem nördlich des zentralen Platzes gelegenen Gebäude die Nahversorgung des neuen Quartiers realisieren: zwei Supermärkte, mehrere Einzelhandelsgeschäfte und eine zum Quartiersplatz hin ausgerichtete Gastronomie. Im ersten Obergeschoss liegen Arztpraxen oder Büros sowie eine Kindertagesstätte im Innenbereich. Die restlichen Flächen und alle übrigen Obergeschosse bleiben dem Wohnen vorbehalten. Menges Scheffler Architekten orientieren sich in ihrem Siegerentwurf an der Blockrandbebauung als Grundgerüst für eine hybride Gebäudenutzung. Mit unterschiedlichen Gebäudehöhen reagieren sie dabei auf die angedachte umliegende Bebauung. Der Wohnungsbau mit seinen unterschiedlichen Gebäudetiefen profiliert und gliedert die Baukörper zusätzlich. Auch hier soll ein Teil der Wohnungen öffentlich gefördert werden.
