Sub-area 1: ‘Brandenburg an der Havel’

With the planned construction of the third and fourth railway rings in the metropolitan area, it is conceivable that Brandenburg an der Havel can be densified to accommodate twice its current population. The aim of the urban development plan is to promote closer interconnection between city and nature while considering historical identities. The existing buildings between Neustadt and the railway station are structurally upgraded by closing the blocks. The structures within the blocks are largely preserved. Potential development areas are located southwest of the station and in the west of the old town up to the railway line. In addition, south of the station, along the Jakobsgraben canal, the existing buildings, which have a more open composition, are densified with street-fronting buildings. When viewed from above, the expanded block structure harmonises the urban structure.

Sub-area 2: ‘Westkreuz’

Currently, when various transport systems going in different directions intersect, traffic jams and structural overloads occur, especially at peak times. The AVUS (Automobile Traffic and Practice Road) was the world’s first road created specifically for automobiles and was once an important car-racing circuit. It is redesigned as a boulevard in this concept. The car traffic is redirected underground, and the rail traffic is above ground. The track systems are converted into a green space that connects the nearby Lietzensee Park with Grunewald. The north curve houses a new football stadium, and the urban planning additions adhere to the Charlottenburg block structure. The dominant element is a gate-like situation formed by two highrise buildings with a height of up to 200 metres. A similar ensemble is also to be built at the three other train stations.

Sub-area 3: ‘Berlin-Mitte’

Only a few entries focused on Berlin-Mitte. The centre is roughly based on the historic centre of 1920. Parts of the neighbouring royal city are also enhanced based on the city plan from 1920. The Stralau Vorstadt (Stralau Suburb) is densified along the street with large residential buildings. The concept supports the idea of strengthening the historic centre with historicist architecture and additional cultural facilities. The existing housing will enter into a ‘coalition’ with the reconstructed city plan. Peter Joseph Lenné’s idea of integrating ‘jewelled water axes’ into the city is revisited. The concept proposes extending the waterway from the Engelbecken in Kreuzberg to Volkspark Friedrichshain via Strausberger Platz. The waterway is to be designed on both sides as a green space with avenues and recreational spaces.

Star-shaped Archipelago Berlin-Brandenburg 2070 – Urban Development Concept
Berlin-Brandenburg was formed out of various villages and towns. This development has led to an archipelago of centres, within and beyond Berlin, that are connected by radial axes and circular railway rings. The structure ­within Berlin’s inner railway ring is characterised by green islands in the dense, urban sea of houses; beyond the ring, it is characterised by settlement islands separated by green and natural spaces. Between the radials of the star-shaped structure of Berlin, the large landscape areas protrude far into the centre of the metropolitan region. The star-shaped archipelago, with its dialectic between nature and development, represents the greatest qualities and potentials of the Berlin-Brandenburg metropolitan region. These need to be strengthened and further developed. New building sites and residential areas should be created largely within this structure based on the conversion, consolidation, and modification of existing settlement areas. The current star-shaped structure of the Berlin-Brandenburg metropolitan region is to be expanded and differentiated with the star-shaped archipelago model proposed here. The concept of the star-shaped settlement – especially in conjunction with its visual representation in the Berlin-Brandenburg regional development plan – evokes a sense of unlimited densification within the star-shaped settlement structure. As such, it does not consider the infiltration of urbanised areas into the surrounding nature. The concept of the star-shaped archipelago, which is based on the concept of Berlin as a ‘green archipelago’ and on ideas from the Greater Berlin Competition of 1910, is to pursue this dialectical interpenetration of city and nature as a new model.

Sub-area 1:

At the edges of the settlement radials, areas are divided into small parcels to promote a mix of uses. This not only stimulate agriculture, but spatially defines the populated areas. The parcels structure a dense network of paths and create parklike landscapes. Existing settlements are supplemented, and new development areas for housing, recreational activities, and energy facilities are set in a spatially defined environment. This in-between landscape can be used as an experimental space for organic farming, decentralised energy supply, and alternative settlement areas, which simultaneously counteracts urban sprawl. Special places are marked and represented in the form of zeros, or circles. As a result, individual uses such as small settlements, agricultural businesses, and energy systems can be placed in the landscape.

Sub-area 2:

Inspired by the spatial arrangement of allotment gardens, ‘parcels’ measuring 150 x 150 metres are defined. Each of these clusters can be divided and expanded to accommodate different uses. The supply of energy and water is decentralised and is managed through collective self-government. 50 per cent of each parcel must be cultivated agriculturally to maintain the character of a park landscape. The parcels are enclosed by hollows and depressions, which ensure the retention and infiltration of surface water along the path system. The planting of trees and hedges creates natural corridors that improve the microclimate. The outlined grid depicts the network of public paths. The parcels are awarded in the form of heritable leaseholds based on concept-based applications. This land-use concept promotes social and ecological forms of living with the aim of establishing a ‘transition society’ for more open
and flexible lifestyles.

Sub-area 3:

There are allotment gardens with low structural density along main access roads such as the A114 and the suburban railway line between Französisches Buchholz and Blankenfelde (including the Blankenfelde railway station and a new possible railway station on Bucherstrasse). These areas are suitable for new developments, particularly since technical infrastructure and public transport are already available. Here, the concept is centred on orderly densification along the radials. Existing landscape elements such as avenues, alluvial meadows, and the Panke River are renaturalised. The desired mixed-use environment, which includes housing, office spaces, manufacturing, and logistics centres, generates a variety of building typologies that allow high structural density. In the areas that transition to the historic green villages, the design places housing estates with single-family homes and integrates a small part of the allotment garden settlements into the landscape area.

Entrant‘s description

Berlin is growing, and with it, the surrounding areas in Brandenburg. Over the past century, Brandenburg and Berlin have become increasingly inter­con­nected due to developments along the transport axes that make up the rays of the star-shaped settlement structure. It makes sense to further develop the ­Berlin-Brandenburg metropolitan region along existing infrastructural lines and arteries and to consolidate the star-shaped settlement structure. However, a new perspective and a future-oriented economic and social vision are needed. To this end, we must strengthen the Brandenburg regions surrounding Berlin in response to the dynamic expansion of Berlin’s centre.
The development model for the metropolitan region should be based on three initiatives. First, we need to regenerate the landscape as an ecological environment, social milieu, and economic force. Second, we need to create an interface between the city and countryside. This interface must be marked by a legible outline within the star-shaped settlement structure; and it must serve as an ‘ecotone’, ‘edge habitat’, or ‘transition area’. Third, we need to interconnect the radial axes with green areas and water and link the settlement rays with orbital streets surrounding them, thus developing the star into a network.

Sub-area 1: Tempelhof – Südkreuz

The area between Südkreuz and Tempelhofer Feld along the suburban railway line currently consists of abandoned commercial sites, railway facilities, allotment gardens, peripheral areas near the former Templehof Airport, and remaining areas surrounding the Südkreuz railway station. The A10 metropolitan motorway and the suburban railway ring dominate the urban situation. The design demonstrates how one can further develop these districts based on the existing nineteenth-century urban structure and clearly distinguishes it from the garden city of Neu-Tempelhof (also known as ‘Fliegersiedlung’ – ‘Aviation Settlement’). The buildings along the railway ring function as distinct urban borders. For the Aviation Settlement, the development proposal adheres to the proportions of the existing residential buildings in the sub-areas. The development along the railway line mixes housing, workplaces, and essential amenities. The additional buildings south of the airport building, like the building itself, accommodate cultural and research institutions. A group of three high-rise buildings marks the centre and forms a gateway to the south.

Sub-area 2: Bernau

There is great potential for urban development to the northwest and southeast of the Bernau railway station. Two conversion areas along the railway line, which penetrate into the surrounding landscape to the southwest, consist of settlements with transport infrastructure that are intended to initiate a new phase of mixed-use urban development. The proximity of the A10 and A11 junction and of inexpensive local, regional, and long-distance rail connections support the idea of urban expansion at this location. The concept foresees high densification here, in contrast to the existing districts. In the area surrounding the railway station, block structures have been developed that enclose the railway line and open to the north and south. To the northeast, the conversion area is lined with a series of U-shaped buildings that form a large-scale addition to Panke Park. The auxiliary functions in the southwest area are intended to support tourism and accommodate a wider range of recreational activities.

Sub-area 3: Schwedt an der Oder

The former royal seat of Schwedt an der Oder, which was badly destroyed in the Second World War, lies on the northeastern edge of the regional development plan. The town of Schwedt would benefit greatly from a rail connection along the existing Berlin–Stettin line. The design concept envisages establishing this connection and incorporating the central station area of Schwedt into a new urban mixed-use location. Gaps and remaining areas in the urban structure are filled, and new constellations are developed – based on the concept of critical reconstruction – to revive the historical city layout. A unique selling point is the landscape of the lower Oder Valley with its nature reserves and national park. Uniting the urban development more closely with the river landscape would not only strengthen the area around the Uckermark areal with the former royal palace but would also signify an upgrade for the entire city.

Growing Together: The Landscape City
Berlin and Brandenburg Will Grow Together

A future concept for the Berlin-Brandenburg metropolitan region not only requires cooperative political processes but must also include a master plan for the city and the surrounding countryside. This plan is based on historical considerations and on the existing potential and characteristics of the ­Berlin-Brandenburg urban and natural landscape.

Towns in Berlin and Brandenburg will expand inwards. Berlin has great potential for internal growth, densification, and spatial optimisation. This potential can be realised through the use of vacant lots and brownfield sites and through the transformation of existing infrastructures. Berlin’s green character must also be preserved, as it embodies a matchless legacy of urban planning and will be increasingly important for the area’s climatic balance in the future. Towns in Brandenburg also have much capacity for growth within their borders. This inner growth can preserve and bolster the particular characteristics of the state’s more urban areas. Railways will ensure future mobility and transport. Against the backdrop of climate change and the energy transition, the expansion of the road and motorway network is not a satisfactory solution for the future. In contrast, railway transport allows for a more sustainable future driven by the digital revolution. The future growth of the city will take place near new railway lines.
