With the development of the ecovillage in Hanover, there is a great chance to make an important contribution to future-oriented urban development. One of the most specific features of the ecovillage, and its guiding principle, is sufficiency. To possess more by sharing more: a highly flexible approach that, here, is not only preached but also practiced. In addition to a co-working space and several workshops, ecovillage also offers common rooms in the buildings and gardens that belong to and can be used by everyone, and there is even a special guest house for visitors to stay the night.

The nucleus of the urban design is the lively village square, that is surrounded and framed by the commons. This is the green heart of ecovillage; where water is being managed, food is being produced and the spirit of community is being lived.

One of the drivers for the development was the ambition to become a CO2-neutral settlement. Everything is built from wood, and the sealing of the surfaces is being minimized as well. Biodiversity is promoted and gray- and rainwater are treated and cleaned with the help of a plant-based sewage treatment system. After being directed into a biotope-like lake, it seeps away and evaporates, or serves the residents to water their gardens.

The mobility concept also sets high goals with regard to future viability: it focuses entirely on local mobility. (local public transport, as well as pedestrian and bike path traffic). In concrete terms, this means only 0.2 parking spaces per residential unit are provided. In return, however, there are generous areas for bicycles, rental stations, handcarts, etc. A direct connection to the light rail system rounds off this concept.

The neighbourhoods, which are connected to each other and to the centre by the commons, consist of differently sized clusters. These clusters comprise various building typologies, which in turn provide space for a wide range of apartment forms. This 'democratic' housing mix promotes social integration and creates strong neighbourhoods.

ecovillage can be regarded as a pioneer in a long-overdue discussion of principles in which frugality is pursued as a philosophy.

The projected population development up to 2035 also shows the trend towards a housing shortage in Herne. Despite this development, vacancies and underused space potential characterize the waterfront area. Due to the strong commercial and industrial character of the area and the dominance of large infrastructures, the existing residential areas are exposed to high levels of noise pollution. A lack of open spaces and cultural facilities, difficult permeability for pedestrians and cyclists, as well as major weaknesses in local mobility, which is too strongly oriented towards private motorized transport, exacerbate the problem of isolated residential areas and the associated social imbalance in the area. Underused areas, vacancies and wastelands lack a coherent development perspective. Added to this are the deficient conditions in the housing offer and the external influences of the climate, energy and health crises with their very own challenges. This downward spiral must be counteracted by integrated and future-oriented planning for the entire area of the water locations. The planning objectives therefore focus on a diversified range of housing with a high degree of social diversity and programmatic mix; on the integrated development of high-quality commercial areas and the harmonization of housing, work, industry, open space, leisure and transport. A multimodal, transport connection and the structural, open-space networking of the entire area are the key factors.

Multimodal transport connections and the structural, open space networking of the entire area play a key role. Overarching climate goals come into focus and are linked to ongoing processes such as the coal phase-out or flood and heat protection through the Emscher conversion and sponge city principles.

In addition to the university, the campus is also home to the Technical University, the University Hospital Schleswig-Holstein and other research institutions. In the course of the redesign, strategic guidelines were developed to steer the growth into a cohesive campus. The focus was placed on the development of existing structures and the preservation and qualification of green spaces. The development strategies are independent of each other in terms of content and time and can react flexibly to unforeseeable events.

The profiling of characterful subspaces provides orientation in the placement of new functional modules, creates synergies between them and serves orientation within the campus through recognisability. In addition to high-quality places of arrival, a knowledge path creates clarity in the circulation of the quarter.

In order to become an independent, lively district, the aim was to intensify use through residential uses and community facilities. Underused places are activated and reprogrammed. The sense of belonging to the city is reinforced by numerous links with the surrounding area. Existing barriers such as fences are removed.

The concept for the Patrick Henry Village in Heidelberg transforms the former mono-functional military barracks into a multifunctional and identity-creating living environment. The city is being created by the landscape and uses it as a „green zipper", creating a generous connecting space for the inhabitants.

The design offers the potential to rearrange existing deficits in the monofunctional and structural building and open space structures of the current rows of existing houses from the 1950s, to differentiate them in their design and to program them in many ways. The result is a lively quarter for people and nature with open spaces and buildings made of wood that can be used in a variety of ways. Achieving these goals requires:

• A differentiation of the open space framework into rooms with their own characters, functions and possible uses for different age and interest groups.

• the creation of a diverse landscape to promote biodiversity, improve the microclimate and strengthen local material and water cycles. The two green fingers are designed extensively close to nature, have a large number of biodiversity areas, integrate the tree population and take up the existing topography. The areas are not only becoming creatively powerful elements but also serve to balance residents and residents and as a living space for animals.

• A sensitive transformation of the building stock and urban development accentuation of the community fingers through a variety of structural additions in timber construction.

• the establishment of open ground floors with a high degree of mixed-use along with the community fingers as well as the creation of a wide range of living space. From a daycare centre to a laundromat and neighbourhood shops for residents, there is also space for commercial use of the Fab-Lab and Maker Space, through to factories, exhibitions and events. The available living space is enriched by other, diverse forms of living (small apartments, cluster apartments, shared apartments, family apartments, old people's living, etc.). At the same time, the character of a quiet residential area at the transitions to the Green Fingers is retained.

• the further development of the existing stock in favour of the grey energy that has already been used.

• the focus on future-oriented mobility, ie "mobility as a service" and active locomotion. Well integrated into an environmental network of trams, shuttle buses and district garages along the parkway, low-car mobility is planned within the district, which is geared towards cyclists and those walking.

How to raise a dike in an innercity environment?

Nexus, from the Latin 'nectere', means a "connection or series of connections linking two or more things". Marconiplein is, indeed, at the crossroad of different flows: not only mobility but ecology, water protection, development.

Our vision is rooted in the understanding of this space as a complex node, where traditionally, absolute priority has been given to transport. Our proposal aims to invert the paradigm of Marconiplein as a space - a sum of several leftover spaces- defined by infrastructures, but rather, addressing high-quality public spaces first, where infrastructural strategy follows. The design of the new square will be led by the principle of unveiling. If in history, infrastructures - considered as a major source of disruption - have been buried, hidden and elevated, technological progress and accurate urban solutions, offer now the opportunity of reconnecting to infrastructures.

Specific solutions will range from sloping squares, new vertical cross-views, increased number of entrances, fostering the square as a seamless public space, where infrastructure is no more perceived as separated from the city.

How can we create a modern suburban environment suitable for pedestrians in a 15-minute neighborhood - a new district with its own urban character that can withstand the ever-increasing pace of changes in human society?

This is achieved by creating a car-free district that emphasizes pedestrian and cycling transportation, designing compact development that forms both a clearly defined public space and an attractive living environment for future residents.
The concept of approaching public spaces stems from the fundamental idea of relocating cars to the outer edges of the development. The majority of parking spaces are condensed into three mobility hubs on the corners of the site. The implementation of blue-green infrastructure and the provision of quality public space for the residents of Slaný form a better connection between an agricultural park in the west to the city center in the east. With all amenities within reach and accessible recreational areas, the neighborhood will ensure a healthy and sustainable living environment.

Part of this design is the establishment of a central green axis, functioning as a retention valley and providing space for trees and biodiversity. It directs the outer landscape and waterflows into the new neighborhood and results in the
creation of a vibrant blue and green boulevard featuring diverse private and public spaces.

The urban structure that forms this proposal has been carefully crafted to create compact development with a diversity of typologies and financing models. It is also based on simplicity and elegance for sustainable and prospective construction methods, along with a reliable approach grounded in a connection to nature.

BLUE-GREEN NEIGHBOURHOODS

The design taps into the potential to create a green, climate-adapted and carfree district for Münster Hiltrup that blends harmoniously into the existing landscape and settlement structure. Four compact neighborhoods with a large contact area to the open space will be linked by diverse green corridors in the interior (Green Delta) as well as a close-knit network of cycle paths and footpaths and attractively connected to the outside. Motorized traffic is reduced to a minimum and parking spaces are bundled. Within the neighborhoods, the mobility hubs form everyday hubs. A small-scale, differentiated development structure with ground floor uses at the neighborhood squares, social functions and various, mixed typologies suggest a people-centered scale with a rural character. In conjunction with an innovative climate adaptation concept and high ecological and energy standards, a future-oriented neighborhood development is being created for Hiltrup.

Rainwater management follows the principle of the sponge city with the aim of minimizing intervention in the natural water balance, achieving near-natural rainfall-runoff behaviour, ensuring sufficient purification of the surface runoff that occurs, preventing flooding in the settlement area and reducing the runoff peaks into the watercourses to a natural level. Implementation is carried out as far as possible using near-natural methods with a small proportion of technical structures. In addition to the purely water management aspects, ecological benefits such as increased biodiversity and heat reduction are achieved. At the same time, blue-green structures are created that allow residents to experience the element of water.

The Magnum site's DNA of industrial heritage and landscape succession forms the starting point for the transformation into a climate resilient neighborhood. The unique character of the former steelworks is expressed spatially in the overlapping of the scales of human, machine and nature and of the atmospheres between narrow alleys and wide squares.

This productive interplay continues to write the history of the Magnum site in constant change. Three subspaces (water courtyards, forest campus, factory cluster) derive from the site, each with its own independent profile, which form synergies with each other and with the neighborhood. The Magnum Mile connects the three subspaces as a lively backbone of the quarter and the adjacent urban spaces to the west and east.

For the quarter, own systems for the handling of water and soil are developed. They will be used for irrigation, gray water utilization and cooling of the quarter. The goal is to minimize erosion and soil exchange. As much accumulating water as possible is to be collected, filtered and reused. To do this, it will be stored in building-integrated cisterns. Materials collected are reused as much as possible. Existing structures, such as the grove or also hall structures are integrated and the character of the open space and the building structures are developed. The transformation is designed as a gradual, learning and appreciativ process.
