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.

As part of the CEWI-cooperation, Cityförster is developing an implementation concept that shows how the sustainable and careful renovation of real estate can be implemented in the DJH Landesverband Baden-Württemberg e.V.

The mission for DJH Lochen is to be a flagship project for circularity, sustainability and sufficiency. This concept is translated to the offer of the youth hostel, and the architectural design and planning. Following the didactic focus of DJH Baden-Württemberg, the hostel should offer its guests an educational experience for sustainable awareness. This means programs with sustainability themes, active outdoor experiences, and workshops with local resources. These themes are also represented in the architectural concept. The main target groups are school groups, leisure (sports) groups, conference groups, and individual travelers like hikers, cyclists and retreat participants.

The theme of sufficiency has guided the hostel to rethink its offer of rooms: smaller rooms to emphasize the outdoor experience, and the development of a summer house for the peak season. This summer house provides extra guest rooms in the warmer months, making a low-tech building without heating or cooling possible. The summer house transforms the old garage by extending it with a new floor on top. Upon arrival, the summer house is the eyecatcher of the circularity concept.

The main goal of the renovation is to restructure the rooms and meet today's requirements. Because the exterior was renovated in 1982, the focus of the renovation is on the space plan and installations. This means a minimal renovation is sufficient. Where possible, building components are harvested on site or in the region, and repurposed in the summer house and the youth hostel. Where larger quantities of materials are needed, materials based on recycled resources and granulated raw materials are applied, for example recycled rubber, concrete and repurposed wood shingles.

The beautiful location of DJH Lochen next tot the Lochenpass creates an inspiring natural environment in the forest on the hills. The existing outdoor facilities are upgraded, and new functionalities are added to extend the possibilities for outdoor activities. The new multifunctional outdoor spaces contribute to the sustainable outdoor experience of DJH Lochen.

The Dutch government aims to address housing shortages by creating 1 million extra houses by 2030. Ministerie van Maak organized an exhibition during the International Architecture Biennale Rotterdam, showcasing solutions for housing construction, energy transition, and climate change adaptation. The exhibition featured a large Dutch model designed by 100 architects and urban planners. CITYFÖRSTER was one of the selected studios to conduct research into the development of 10,000 climate-proof homes within their 2 x 2 km area.

Our site is located in Arnhem, close to the Central Station and including a portion of the Nederrijn. The site is characterized by a large industrial area, that is divided from a residential area by a railyard leading to Central Station. The river on the other side appears as an unused potential, as well as many undefined areas, that could use more clarity and densification.

How to add 10.000 houses in this area? Our proposal is based on two main strategies:
Former industrial areas are the favourite location for inner city developments. The new housing developments would be realized close to existing roads and transport and urban sprawl can be prevented. We suggest smaller scale infill into industrial areas at underused spaces such as parking areas and expansion areas and to make new connections to the river's floodplains.

The other large potential to add quality by densification is in the low-rise neighbourhoods. Built in the 60's and 70's these areas are at the end of their first lifecycle, often inhabited by empty-nesters. We can add a couple of apartment blocks, diversifying the housing stock and the existing rowhouses could easily be topped-up with an extra layer. This creates both more housing opportunities and diverse neighbourhoods and is also an investment opportunity creating wealth on a small scale.

Both of our strategies use the 10.000 houses not as a problem that needs to be solved, but as a great opportunity to improve our existing city.

How can we ensure that the 1,000,000 new homes that are needed in the Netherlands before 2030 exert as little pressure as possible on the already difficult-to-achieve climate targets? Even if all future homes are built according to the current agreements (BENG [nearly energy-neutral building], and 4% emission reduction in the industry), the CO2 budget for construction (under a 1.5-degree warming scenario) will be used in 2026 already.

As the construction sector, we are currently responsible for 38% of all greenhouse gas emissions. The problem is definitely gaining momentum in the debate; however, the focus within our professional community seems mainly to be on single methods or materials - whereas the solution lies in an integral approach.

Carbon-Based Design is this approach. It provides insight into the CO2 cycle and what role the construction sector and the circular construction economy play in it. The focus is on embodied carbon (or material-related emissions during the production and construction process) in residential construction. By gaining insight into the construction process and which parts of it have the most impact on the total emissions, we can adjust our design and development strategy accordingly. The aim is clear: to design and realize buildings with the lowest possible CO2 emissions, or ideally even CO2 storage.

With a focus on the emissions of production and construction and the ratio of operational and embedded energy, we found solutions for the way from carbon exploitation to carbon sequestration.

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.

The Buna river delta, situated in the southeast of Shkodra, Albania, is intricately connected to Lake Shkodra via the Buna, Drin, and Kir rivers, forming a complex hydrological network. This region boasts diverse ecosystems, drawing migratory birds and nature enthusiasts. However, it faces periodic flooding, attributed to factors like heavy rainfall, snowmelt, imbalanced reservoir management, and the mountainous terrain constraining water flow.

We propose a vision for the future of the Buna Delta, developed in close collaboration with the Municipality of Shkodra, government agencies, international donors and local experts. In this vision, flood protection infrastructure is harmoniously combined with the development of ecotourism and circular economy, as well as the improvement of sustainable mobility between the Adriatic Sea and Shkodra.

To achieve flood resilience, a combination of natural and technical solutions is recommended. A combination of natural and technical solutions is recommended to strengthen resilience to flooding. Among these solutions is the organic development of a green river connecting the Buna and Drinasa rivers. This green river acts as a natural strip of land to divert flood water while promoting attractive vegetation. This improves water quality, creates habitats for wildlife and promotes tourism.

To further protect against flooding, improve biodiversity, develop tourism and promote sustainable land management, measures such as the inclusion of storage areas and buffer zones along the waterfront and a resilient mixed form of agriculture are also proposed.
By implementing these strategies, the Buna Delta can thrive as a resilient and vibrant ecosystem, providing both environmental and economic benefits for the region.

The focus of our project is, on one hand, the careful urban integration of approximately 43,000 m2 GFA (realization part) and 10,000 m2 GFA (conceptual part) of dense housing into the existing morphological and ecological context, taking into account imposed restrictions and desires. On the other hand, the identity of our project arises from intense coordination and integration of urban planning, architecture, ecology, and landscape design.

Characteristic of the existing urban structure of the broader surroundings of the competition area is the loose construction with small and medium-sized structures. In contrast to this morphology, the future urban fabric east of the railway track is planned as an urban densified perimeter block structure (Munich Northeast Ideas Competition). Our project establishes a context-related connection to these two different spatial conditions while simultaneously creating its own strong local identity.

To achieve this, our design is structured into overlapping levels of order, creating differentiated and precise spatial relationships: The construction structure is divided into four typologies. In the west along Marienburger Strasse, the existing structure of rowed, rhythmically offset, small-scale buildings is appropriately complemented to ensure spatial permeability. This is followed by a loose sequence running north-south of individual building volumes (urban villas) increasing in mass and height, set in a landscape park-like arrangement. A third row consists of elongated structures on the east and north sides, which are more monolithic and taller in the northern part, gradually transitioning to a sequence of architectural individual units towards the south.

The primary focus of our project entails the resilient and environmentally conscious transformation of two Plattenbau buildings situated on the outskirts of Erfurt, with the objective of establishing a model that can be universally applied throughout the entire neighborhood. The volumes of the two buildings are enveloped by a prefabricated modular grid system, thereby creating an aesthetically refined and low-maintenance design. This approach facilitates not only the seamless integration of novel features, such as entrances on the north side and more expansive balconies on the south side, but also fosters the customization of living spaces and engenders a vibrant sense of community. Additionally, a continuous base serves to integrate the building into the surrounding street context, thereby reinstating a harmonious relationship with the adjacent neighborhood.

Our material choices prioritize economic and sustainable utilization. Easily replaceable wood is employed for planter cladding and facade, complemented by natural fiber insulation and plant charcoal to offset the CO2 emissions associated with the concrete structure. Concurrently, the primary load-bearing structure is composed of concrete, ensuring both fire safety and minimal maintenance costs. A pivotal aspect of our climate-resilient transformation involves the incorporation of greenery on the facades to positively influence the microclimate in the vicinity of the building. This is coupled with a comprehensive rainwater management system, incorporating storage for utilization and retention during intense rainfall events. As a contribution to biodiversity, an assortment of plant species is judiciously combined to provide a year-round supply of flowers and sustenance for insects and birds.

The Rinia Complex is located in a former youth park in the center of Fier, on a plot that is open to 3 sides, facing different contexts. Our design for the mixed-use complex addresses these contexts, which represent the different and differing needs of the area. The building seeks to express the ambitions of the City of Fier, that is: to create a new image, one that is fitting for a city that is dynamic and continually growing, and to add important functions to the city like a public 25m pool and a cinema.

Rinia Complex is a truly multifunctional building, with a program that also includes a 5-star hotel, 2 floors of parking space, residential units, a bank, a shopping center, a restaurant, and a casino. All public functions of the complex are accessible directly from the street via external staircases and are embedded into their urban surroundings. The building has been designed to be used in different ways at different moments throughout the day, offering both public/open access and private/restricted access areas. The intricate program has been fitted into a single volume, a uniquely shaped building that is internally 'fragmented' in order to give an answer to the different needs and the diversity of the context, but which also retains its flexibility as an urban 'shelf' that can take on a variety of functions.

"Branch in the Landscape" presents a holistic concept that includes both the planned cycle and footpath connection across the Neckar and its relationship with the surrounding urban landscape. The focus is on providing residents and visitors with attractive incentives to switch to environmentally-friendly mobility. Urban planning, traffic, and design aspects are being developed into a uniform green infrastructure as a catalyst for new uses of the adjacent public spaces.

Not only the residents will benefit from the new connections, but also the future users of the cycle expressway between Mannheim and Heidelberg. The infrastructure is deliberately compact and reserved in space and the cityscape. The functional path connection is supplemented at certain points by programmatic balconies, each of which enables a view of different landscapes and thus creates several places to come together and linger.

Purposefully positioned buildings under the bridge structure (with potential uses such as a café and bicycle workshop) not only create a local path through the treetops but also create a new urban edge. Together with the bridge structure, this edge forms a new city gate in the west of Heidelberg and at the same time offers noise protection for the newly created Gneisenaupark.

"Branch in the Landscape" creates a variety of spaces through the contrast between linear infrastructure and soft landscape, which also strengthens existing biotopes, creates new ones, strengthens the Heidelberg cityscape and helps previously separate neighbourhoods to create new synergies.

In the beginning of May 2018 students and professionals from Albania and the Netherlands went on a trip to Nivica, exploring the village and the region, and drafting first ideas. The team included architects, urban planners, archaeologists, landscape architects and architectural historians. The workshop results built the foundation for the further development of a masterplan for Nivica.

The goal of this masterplan is to develop a model for a sustainable and prosperous rural economy, with touristic potential within Albania but also on an international scale. As a Living Lab, Nivica allows to experiment with alternative forms of (slow) tourism, small scale investment, renewable energy and local food and waste chains. The masterplan combines the preservation of buildings and structures related to the rich history of the region with a sustainable, diverse expansion of the touristic potential.
Nivica is meant to be the prototype for Albania's "100 villages" plan, which sets out to fundamentally rethink rural development in the country

Strolling in vivid nature!

Located in between the high mountains and the Ionian Sea in the South of Albania, the new 2 km long Drymades promenade wants to emphasize this duality by creating an impression of being immersed in nature and the greenery while having the beach feeling at the same time. By using organic shapes instead of straight lines, we create a green boulevard with different scenarios, points of view and vibes.

The division in different zones helps on creating diversity and reflects the varieties and characteristics the area presents. The promenade aims to be an experience in itself with more quiet and natural zones on the side and a vivid part, the hotspot area, in the middle. Here you can find an underground bar which also serves as an elevated plaza or also a pier on the water with different functions on it. The project is unified by common elements, materials and concepts along the promenade such as stone walls, sand-coloured concrete paving and cut out stone or furniture in corten steel.

One of the key elements of the project is the planting in random dispersion. It serves as shading but also helps at shaping the promenade and giving different scenarios and points of view.

The kiosks, which are always located in the planters, provide the necessary services needed on the promenade. While the fixed bottom part is made of stone walls, the upper part is made from wood and is thought of as a flexible element that can adapt to the different functions and needs. The biggest kiosk serves as a bar and eating place, the smaller ones as newspaper or ice cream shops, and the smallest ones as public toilets and changing rooms. The roof made of corten steel makes the structure a sustainable one. It is slightly elevated from the main structures to allow the air to pass through and cool the structure underneath. It also collects the rainwater and with the proper inclination, brings it to the planter on the back.

The residential complex AnA is situated close to the Student Village of Tirana University on a magnificent hillside. The oddly-shaped site starts with a narrow edge along the street and widens sloping down 15 meters of level difference. The building folds as a continuous figure, respecting all the necessary distances to the property line and on itself. This stepped form creates a local landmark with an identifiable skyline in a very heterogeneous context.

The site opens itself to allow a pedestrian connection between the student village and the northern areas. This passage enlivens the commercial ground floor and the compound piazettas. The cuts in building volume are a response to the urban regulations and a way to break down the overall massing into pieces more related to the human scale. The same 'cut' approach is used in order to provide light and natural ventilation for circulation spaces. The attic floor has setbacks in strategic locations of the building for best views from the terraces for the exquisite apartments. The materialization aims for an elegant appearance with differentiated materials and patterns but an overall clean white look: the plinth is of fair-faced concrete with a diamond-shaped relief, the body from white plaster, crowned by an attic floor clad in beveled tiles for a shimmering reflection of the strong Albanian sun.
