Lagodekhi Protected Areas (LPA) in the extreme north-eastern part of Georgia at the southern slopes of the Caucasus and with altitudes from 590 to 3500 m, is one of the world's best-preserved areas with diversity of natural landscapes. The project of developing a TreeTop Trail as a new touristic product is to attract more visitors and, considering the transboundary potential of the LPA, make it one of the most attractive destinations, to be included in future transboundary ecotourism products.

The concept emphasizes the forest as the protagonist and proposes a minimalistic design, a circular shaped trail that gradually ascends towads the tree canopies. Additional program is added in order to enhance the experience of forest. This includes a watch tower, a dome, a large net, a cave, and multiple platforms.

The new primary school with 2-court sports hall combines high architectural quality with clear functional structures and a sustainable concept that promotes long-term education and community.

4 buildings - 4 wings:
The school uses are divided into four clearly structured buildings, which are arranged along the common centre. The public areas - sports hall, music school and community library are located in the north and open up towards the town.

Centrality:
The 'Common Centre' forms the heart of the school and combines communal and external
uses into a harmonious overall structure. It links the open spaces and creates a flowing transition between indoor and outdoor spaces.

Connections to all sides:
The central axis links the school in all directions. Side entrances integrate between the buildings on the ground floor and create small, informal passages. At the same time, separate entrances provide access to independent utilisation units.

Sustainable learning houses:
In accordance with the "house within a house" principle, the classes and differentiation rooms in the new self-sufficient learning houses are organised around an educational centre. Concentration,ncommunication and play find the right space here.

The transformation of Trnavské Mýto into a dynamic cultural and urban hub is entering its next phase. With the building permit secured, Istropolis—designed by CITYFÖRSTER and KCAP in collaboration with Immocap—will break ground in summer 2025.

The project will introduce a state-of-the-art concert and congress hall, modern residences, and high-quality office spaces. The 3,000-person venue will host diverse cultural and business events, featuring in-the-round seating and multi-event flexibility. Offices will include a grand atria and flexible workspaces, while the residences will be nestled within green courtyards and pedestrian-friendly streets.

Istropolis sets new standards in sustainable urban development, integrating passive climate solutions, energy-efficient design, and biodiverse public spaces with 147 trees, 70 local plant species, and dedicated cycling infrastructure. Long overlooked despite its central location, Trnavské Mýto will soon be revitalized with green promenades, fountains, and a lively public square, supporting markets, gatherings, and everyday life.

With construction set to begin, Istropolis moves from vision to reality, shaping the future of Bratislava through architecture, sustainability, and vibrant public life.

Tirana Crevices—a 160-meter-tall mixed-use tower in the heart of Albania's capital, designed as a civic landmark that integrates culture, housing, work, and leisure. The design features two elegant towers with crevice-like collective spaces, providing shared amenities at intermediate levels that act as public breaks in the vertical city. Designed in partnership with LOLA Landscape Architects, the ground floor is elevated, creating a public landscape of rocks and water that engages the surrounding neighborhood, while the building's façades are clad in locally sourced natural stone, with distinct materials highlighting the communal areas and reinforcing their programmatic significance.

The design introduces a composition of two elegant towers placed on a cityscale four-floor plinth, each structured as stacked blocks with equal proportions.These blocks are subtly shifted creating crevices —communal spaces that offer a civic and social dimension throughout the vertical structure.

To enhance public integration, the building is lifted from the ground, creating a generous landscape beneath it—an open space inspired by rocks and water, developed in collaboration with LOLA Landscape Architects. This gesture grounds the building in its context and invites the public into the site, making the project not only a residential development but also a new urban anchor.

The Henschel Quarter opens up hertitage sites to the public and secures them through flexible use. It is integrated into the city and is accessible to everyone. The aim is to preserve the historic industrial culture and make it usable. Listed buildings are carefully restored and remain part of the public space. The industrial past will be preserved through minimally invasive interventions, while new and predominantly commercial uses will revitalize the old halls. The open space will be transformed, historical traces such as tracks and crane runways will be preserved, supplemented by green spaces and playgrounds. In terms of urban planning, small-scale building typologies create the transition to adjacent districts, while high points mark important locations. Connections for pedestrians and cyclists create a continuous and close-knit network in the district. The existing buildings will be supplemented by new buildings whose design is based on the industrial character. Historic parts of the buildings will be retained and partially integrated into the outdoor space. In the center of the quarter, a "hall for all" with restaurants, culture and sports will be created, surrounded by creative and commercial uses.

The Henschel Quarter focuses on sustainability by preserving the existing buildings and reusing gray energy. Demolition materials are recycled on site and new buildings are constructed from sustainable materials. Renewable energies such as solar panels and geothermal energy supply the quarter, while open spaces improve the microclimate, and the combination of history, commercial, cultural and innovative offerings makes the Henschel Quarter a vibrant part of Kassel.

Urban integration creates a neighborhood
In its immediate surroundings, HIGH Q picks up on the typological and urban development characteristics of its neighborhood. The existing principles of block structures, incisions and polygonal high points are transferred to HIGH Q in order to create a harmonious overall urban image.
On the west side of the construction site, a neighborhood square with outdoor gastronomy will be created at the interface between the office and the hotel, creating a lively meeting place for everyone. This square also serves as an entrance to the hotel lobby.

Striking appearance creates identity
Whether viewed from a passing train, as a pedestrian or from a bicycle, the HIGH Q always looks different and yet is unmistakable. The special façade design with 6 partial façades makes the high-rise appear slender and without a rear side, creating ever new impressions.

Recognition value and an identity-creating design are an important requirement for this building in this exposed location. On the one hand, the façade and the striking shape create a variety of impressions depending on the viewing angle, while on the other hand the building also offers diverse and special situations in its immediate context. The undercut to Celler Strasse with its forecourt forms a clear address, the neighborhood square offers a common center for the neighborhood and the differently designed facades improve orientation and create different places.

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.

As part of the Centrum Bremen 2030+ strategy, the city of Bremen has recognized the potential of rooftops for the transformation of the city centre and has taken initial measures to implement them. The action plan for roofscapes in Centrum Bremen offers new perspectives for the innovative use of roofs. Private and public owners of retail and office properties and parking garages were supported in identifying the potential of their roofs.

The planned conversion of roof areas is intended to create new spaces for people and nature and revitalize the city centre. Possible uses include social meeting places, cultural and gastronomic offerings, urban food production, the promotion of biodiversity, the improvement of the microclimate and energy production. Pilot projects were to be implemented after examining the structural, constructional and legal requirements and supported by funding of the federal ZIZ program.

However, the project revealed that implementation was made considerably more difficult by structural, building law and economic challenges. Although many owners were open-minded and the urban planning conditions were favorable, funding conditions and structural conditions often did not match. Nevertheless, the concept provides important insights into the transformation of the real estate portfolio and shows that realistic, long-term approaches are necessary in order to achieve sustainable and future-oriented development.

The documentation of the concept of action you will find here.

The design of this project was guided by a desire to enhance both the functionality and aesthetic value of the area. The team sought to complete Engel's visionary concept for Victory Square, creating a central space that would serve as a dynamic and vibrant hub within Dejvice. By closing the semicircle around Victory Square, the project reinforces the strength of the square's geometric design and establishes a clear, cohesive axis through the heart of the UCT campus. This newly completed space offers a destination for students, residents, and visitors alike, contributing to the broader vitality of Prague.

A key aspect of the project was the creation of a new urban layout with carefully designed, symmetrical blocks that prioritized high-quality public spaces. These spaces were intended to be interconnected and easily accessible from all directions, enhancing the flow and integration of the area. The two adjacent blocks, while sharing a similar footprint, respond to their different contexts in distinct ways. The western block features a sunken square at the center of Zikova Street, serving as a lively academic and administrative hub. In contrast, the northern block offered a residential setting with a semi-enclosed courtyard, providing a peaceful retreat for its residents and visitors.

The architecture of the development took its cues from the surrounding Dejvice area, blending modern functionality with a clear sense of place. Each building's facade is designed to reflect its unique function, context, and orientation. The apartment buildings offer flexible layouts, accommodating a range of residential needs, while the office and institutional structures feature large, open atriums that activate the ground floor. These spaces remain inviting and lively year-round, even during the winter months. Additionally, the project prioritized sustainability, with an emphasis on energy-efficient buildings and infrastructure made from durable materials. The surrounding public spaces were designed to promote sustainable transportation options, contributing to a greener, more resilient urban environment.

Urban development
The Change Factory combines flexible uses and high-quality open spaces along the river Inde and Indestraße. A four-storey high building with a roof terrace marks the main entrance and lends urban presence. The three staggered building volumes form a work yard to the north and terraces to the south for working and relaxing on the Inde. To the north, the buildings are stepped down towards the cemetery. To the east is a space-efficient mobility hub, which is directly connected to the main entrance via the internal Innovation Mile.

Open space
The Change Factory forms an identity-forming backbone of the public space along the Inde. A spacious forecourt with dancing trees and seating invites people to linger. To the south, open terraces will be created with a view of the Inde. Trees that are compatible with the urban climate and the integration of the local water balance into natural circulation systems ensure sustainability. Green roofs, vegetation and riverbank areas delay runoff and improve the microclimate.

Organization of use
The building is based on a modular construction grid of 8.1m x 8.1m x 4m or 5m on the first floor. All usage units are flexibly adaptable. The Innovation Mile connects the floors via a spacious staircase and promotes interaction. Upper floors offer communication areas, the first floor presentation areas. A café at the main entrance creates an inviting entrance. Space-intensive uses and laboratories are located on the first floor, while offices on the upper floors offer units from 30m² to over 1500m² and can also be divided and combined.

The proposal for the revitalization of Königstrasse 1ab is based on the following 5 guiding design themes:

Development of a building structure that completes the ensemble of the hotel and Königsstraße 1c, which incorporates heights and gradations, creates addresses and forms the prelude to Königstraße through its orientation towards the train station.

Creation of lively, green passages with small-scale retail, gastronomy and areas for culture and events in the interior of the ensemble and a generous setback on Königstraße to provide more space for planting and passers-by.

Enabling maximum exchange between inside and outside through diverse and generous entrances and transparent façades.

Creating modern retail, office and restaurant layouts that can react flexibly to changing future requirements.

Reuse of the existing load-bearing structure and individual components to minimize energy consumption and thus reduce CO2 emissions.

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 Klimaquartier Würselen is characterized by strong open space references and clearly defined urban spaces. It mediates between the new and existing settlement bodies, the various neighborhoods and the open landscape in the east. In order to meet the current climatic changes and the scarcity of resources, the neighborhood will be developed in a space- and material-saving manner using timber construction; water and other resources will be used locally and treated on site.

The new neighborhood landscape complements the existing open block perimeter while forming defined neighborhoods with intimate courtyards that combine village courtyard structures with play streets. The small-scale buildings surround the Green Center, which forms the heart of the neighborhood and functions as a meeting space for the surrounding neighborhoods.

All buildings are based on the same construction grid, which corresponds to the deep garage grid of 5m. The bulkhead construction method, optimized for timber construction, forms the basis for the feasibility of the various building typologies. At the same time, repetitive building elements and construction principles ensure efficient planning and minimized construction times. The efficient basic structure allows for a variety of floor plan types - from one-room apartments to row houses to group apartments.

The neighborhood at Fuhrenkamp takes on the responsibility of a climate-friendly settlement. The compact development minimizes the degree of sealing and creates generous green spaces with dense tree populations. These air-condition the neighborhood and increase biodiversity. Stormwater management functions according to a sponge city and cascade principles, in which rainwater is retained and temporarily stored, evaporates and infiltrates or is discharged into local ditches. Renewable energy is generated locally.

The use of durable materials, building with used and recycled materials, and a wood construction method contribute to climate protection. Promoting and enabling a change in mobility behavior achieves a low-car neighborhood. The climate quarter creates a social mix by offering diverse, also new forms of housing as well as friendly street spaces for play and circulation, diverse open spaces and neighborhood centers for all generations.

The Fuhrenkamp neighborhood is being developed in phases, beginning in the south and growing out of the city. The development in individual steps makes it possible to learn from what already exists and to make appropriate adjustments to meet changing needs. The edges of the individual neighborhoods in the area react in a differentiated manner to their context: the neighborhoods leave sufficient distance to the section of forest to the west. At the same time, the biotope network is strengthened and expanded in a vertical direction between the existing structures and the new neighborhoods to the east. The new district is holistically interconnected through a framework of neighborhood centers.

How to build using simple means in construction, building services, fire protection, floor plan design and open space and still react to the ongoing questions of climate adjustment and resiliency?

"Build Simply" shows answers to these questions in a 5-step strategy which we developed together with our cooperation partners on levels of structural engineering, building technology and landscape design:

1. Simple volumes connected to an active arcade
2. Intelligent fire protection
3. Reduction of technology through clever construction
4. Use of local energy resources
5. Cradle-to-cradle/Build sorted

On an architectural level, these principles are implemented by public and semi-public spaces aligned to the common yard, the lowest building class possible, continous floor plans for a better ventilation within each apartment and a structure allowing an effective planning with wood. Nevertheless, the main focus of the design relies on the needs of people to promote a
communal and sustainable togetherness
