In Baden (CH), a project combining the renovation of a listed villa with the construction of two additional residential buildings was realized on a steeply sloping, terraced plot on Schlossbergweg below the ruins of Schloss Stein castle. The plans were drawn up by Zurich architects Menzi Bürgler Kuithan and were implemented in several construction phases between 2019 and 2024.

In the center of the property is a three-story villa from 1923, which was designed by Hans Loepfe and is a listed building. It is characterized by the symmetrical façade structure and a hipped roof with a kink. The building was renovated to preserve its substance and the attic was converted into residential units. Three residential units were created in the process. The work was carried out in consultation with the relevant heritage authorities and relates to the historic substance of the interior and exterior.

In addition to the villa, the site includes a baroque, protected vineyard house on the southern edge of the property as well as a large garden area with terracing, retaining walls and mature trees. The historical topography and existing structure were taken into account in the project development.

Two three-storey residential buildings were added to the site as part of the redevelopment. The new buildings are based on the existing individual buildings in the surrounding area and the dimensions of the Rebhaus in terms of setting, volumetry and scale. The buildings are at right angles to each other, have compact floor plans and pitched roofs. The façade design follows a reduced expression: plaster in light natural tones with a broom finish, wooden window reveals and stepped plinth zones made of exposed concrete. These materials were matched to the immediate surroundings, which are characterized by limestone cliffs and vegetation.

The two new buildings were constructed using timber frame construction with hemp-lime brick as insulation material in the infills. This construction meets building physics requirements for thermal insulation and moisture regulation without synthetic additives. The exterior walls consist of several layers, including clay plaster on the inside, wood-based materials and lime plaster on the outside.

The roof surfaces are fitted with in-roof photovoltaic systems. The roof structure consists of rafter insulation, OSB boards and a visible inner layer of three-layer boards. Concrete slabs with integrated waterproofing were used for the canopies.

The interior fittings follow a multi-layered structure. Floors are provided in various designs: Oak parquet, linoleum or porcelain stoneware on underlay floors with underfloor heating. Impact sound and thermal insulation are mainly based on wood fiber or PIR insulation materials. The ceilings consist of wooden beams with embedded sand-lime bricks, combined with clay building boards and clay plaster.

The fittings are designed for long-term use, with a focus on functional materials, ease of maintenance and ecological building criteria. Windows and doors are made of wood and triple-glazed, some with metal window sills and textile shading systems.

The new buildings were designed to be energy-independent. In addition to the building envelope with hemp insulation and clay plaster, in-roof PV systems help to generate electricity. The construction method takes into account requirements for summer heat insulation and airtightness. Window openings are positioned so that natural lighting and cross ventilation are possible. The buildings are accessed via existing and additional paths. The overall structure of the site remains legible. The new buildings were integrated into the existing garden landscape without altering the villa’s main axes or visual relationships. Access is decentralized, with separate entrances and minimal intervention in the geometry of the site.

Villa Stuck reopens: after 20 months of renovation, the Munich Künstlerhaus shines in new splendor. Visitors can expect not only a modernized museum with barrier-free access and expanded exhibitions – a work by Franz von Stuck that was long considered lost is also being presented for the first time. With special international exhibitions and an inclusive educational program, Villa Stuck is setting new accents in Munich’s cultural landscape.

On October 18, 2025, after 20 months of construction work on Prinzregentenstrasse, the Villa Stuck Museum will reopen its doors. The reopening of the Villa Stuck marks an important moment for Munich’s cultural life, as the building combines history, contemporary art and innovative educational programs to create an overall experience.

The renovation work on the Villa Stuck was necessary to bring the listed artists’ house up to date both technically and structurally. The building was last completely renovated between 1999 and 2004. After more than two decades, numerous technical systems such as air conditioning and alarm technology as well as fire protection systems had to be completely renewed. The aim was to continue to meet international standards for the protection of valuable works of art. The reopening of the Villa Stuck is also an architectural event. In addition to the technical renovations, the facades, sculptures and reliefs were restored. Roof figures, portals and garden walls were carefully restored in concrete in order to ensure their long-term substance and safety. The colorful façade reliefs based on designs by Franz von Stuck himself were reworked, as were the antique casts. The artist’s garden was also redesigned and enhanced with an extended path system and new planting. Special attention was paid to accessibility. In future, the museum will be accessible via the new entrance on Ismaninger Straße. Inside, elevators, checkrooms and sanitary facilities have been modernized to ensure equal access for all visitors.

The reopening of Villa Stuck not only brings technical improvements, but also new spatial concepts. For example, an underground utility room has been created to relieve the garden area and create space for visitors. The historic rooms now feature new furnishings, new hangings and some previously unpublished works by Franz von Stuck. Highlights include the “Fantastic Hunt” (before 1890), the “Vision of St. Hubertus” (1890) and the portrait of a woman from Mainz, newly added to the collection, which was previously only known in a black and white reproduction. Restorations of Stuck’s idiosyncratic painting technique, including the overpainted Baroque painting “Beheading of St. John”, provide new insights into his work. In the music salon, the historical furnishings with vermilion-colored silk curtains have also been reconstructed. In collaboration with the Doerner Institute, an art-technological examination of the wall paintings was carried out, the results of which are presented in special guided tours.

With the reopening of the Villa Stuck, the museum is also launching a new exhibition program. Two central exhibitions accompany the relaunch:

  • “Chicks on Speed. Utopia” – A comprehensive retrospective of the internationally renowned artists’ collective, which has been combining art, music, performance, fashion and activism for 30 years. The show presents works from three decades, including installations, music projects and performances.
  • “Louise Giovanelli. A Song of Ascents” – The British painter’s first major solo exhibition in Germany. In her paintings, Giovanelli focuses on stage sets, rituals and collective experiences between promise and abyss.

In addition, the “Of Books and Libraries” project opens the museum’s own specialist library to visitors for the first time. Here, books can be browsed through and rearranged, allowing interactive access to the collection.

A central component of the reopening of the Villa Stuck is the new educational program. It was developed with a focus on inclusion and cultural participation. In addition to offers for children in cooperation with inclusive daycare centers, there are programs for people with dementia or psychiatric experience. Touch tours and guided tours in sign language take place regularly. Workshops, writing workshops, discussion series and an inclusive museum choir complete the program. Villa Stuck aims to be not just a museum, but a lively meeting place for all sections of the population.

Following the reopening of the Villa Stuck, opening hours have been extended: The museum is open every day except Mondays from 11 am to 6 pm, and on Wednesdays even until 8 pm. A special offer is the “Friday Late” on the first Friday of every month, when the museum is open until 10 pm and can be visited free of charge. For the “Long Night of Munich Museums” on October 18, 2025, Villa Stuck will remain open until 01:00. Admission is also free on the two Sundays following the reopening, October 19 and 26.

The refurbishment was initiated by the City of Munich as the client. Kiessler Architekten were responsible for the planning and implementation, supported by various specialist planning offices for structural engineering, air conditioning, fire protection and landscape architecture. The work is divided into two construction phases: The first was completed in time for the opening on October 17, 2025, while the second will end in spring 2026. Outstanding measures include the complete replanting of the garden, the restoration of the sculptures and the opening of a new museum restaurant and a lecture room in the basement.

The reopening of the Villa Stuck is more than just the return of a building steeped in tradition. It stands for the successful bridging of historical architecture, modern museum technology and a program that allows visitors to experience art in all its facets. With the combination of restored historical rooms, international exhibitions and an inclusive educational program, Villa Stuck is repositioning itself in Munich’s cultural landscape. Visitors can look forward to a diverse program ranging from early childhood art education to interdisciplinary concerts. The reopening of the Villa Stuck thus sends out a strong signal: Art history and contemporary art go hand in hand here, and the house remains a place of lively cultural encounters.

BIM 4.0: How Building Information Modeling is revolutionizing the future of the construction industry

Building design

According to a study from 2022, 70% of large construction companies in Europe are already using BIM. With the introduction of BIM 4.0, which integrates IoT, artificial intelligence and blockchain, these companies can significantly increase their efficiency and sustainability. Robs | Unsplash

Building Information Modeling (BIM) 4.0 is more than just an evolution of the original BIM. While previous versions of BIM were mainly used for the visualization and planning of buildings, BIM 4.0 goes beyond this: it is a holistic solution that integrates real-time data and networks all phases of the construction process. BIM 4.0 builds on the principles of previous BIM versions, but brings IoT, cloud technologies, artificial intelligence and blockchain into the construction process to make it more transparent and efficient.

Building Information Modeling (BIM) 4.0 is more than just an evolution of the original BIM. While previous versions of BIM were mainly used for the visualization and planning of buildings, BIM 4.0 goes beyond this: it is a holistic solution that integrates real-time data and networks all phases of the construction process. BIM 4.0 builds on the principles of previous BIM versions, but brings IoT, cloud technologies, artificial intelligence and blockchain into the construction process to make it more transparent and efficient.

Fun fact: According to an EU study from 2022, 70% of large construction companies in Europe are already using BIM, and over 35% of companies plan to implement BIM 4.0 in the next five years.

IoT (Internet of Things)

IoT-enabled sensors and devices can be used to continuously monitor building elements. These sensors measure factors such as temperature, humidity, pressure and wear in real time and provide valuable data that flows directly into the BIM model. If a building element is in need of repair, the system can generate a warning and proactively suggest maintenance measures.

Artificial intelligence (AI)

AI analyzes the data collected by IoT devices and can detect patterns that escape the human eye. This enables predictive maintenance that recognizes future problems before they occur. AI also supports architects and engineers during the planning phase through simulations and design analysis, which increases the efficiency and accuracy of construction planning.

Cloud computing

Cloud-based storage means that everyone involved – from the site manager to the architect to the facility manager – has access to up-to-date data, regardless of their location. The cloud also enables the processing of huge amounts of data generated by IoT and AI and promotes collaboration between teams worldwide.

Blockchain

Blockchain ensures that all data is stored securely and cannot be changed. Transparency is essential in construction projects with numerous stakeholders, and blockchain ensures that changes can be tracked at all times. This creates trust and simplifies collaboration.

Practical example: For a large office complex in Berlin, blockchain enabled seamless collaboration between architects, engineers and site managers working simultaneously in different parts of Germany. This allowed the project to be completed without delays.

BIM 4.0 enables improved collaboration and optimized processes in all project phases. The following examples illustrate how this technology is used in practice.

Planning phase

In the planning phase, BIM 4.0 provides architects and engineers with a more precise model of the future building. This includes not only the external form, but also the internal structure and possible uses of the building. This comprehensive information can be used to carry out simulations that show, for example, how the building will react to weather conditions or how the planned materials will change over time.

Construction

On the construction site, IoT sensors enable precise monitoring of processes and materials. Data on the progress of construction work and environmental conditions is sent to the cloud in real time and is available to everyone involved. By using mobile devices, site managers and tradespeople can react quickly to problems and make any necessary adjustments.

Facility management

After completion, the digital BIM model can become the basis for facility management. This is where the “digital twin” comes into play, an exact virtual image of the building that contains all current data on the condition and use of the building. Facility managers can use this information to proactively carry out repairs and maintenance.

Practical example: A hotel in Munich used BIM 4.0 in facility management and was able to reduce energy consumption by 20% as sensors automatically responded to the actual use of the rooms and adjusted the heating and cooling system accordingly.

BIM 4.0 offers numerous advantages, but also brings some challenges.

Advantages of BIM 4.0

  1. Cost efficiency: Early detection of errors and proactive maintenance can reduce construction costs.
  2. Sustainability: Optimized planning and usage processes enable a more resource-efficient construction method.
  3. Transparency and traceability: All changes are documented and can be traced by everyone involved.
  4. Global collaboration: The cloud enables teams from different locations to work together effectively.

Challenges during implementation

  1. High implementation costs: Switching to BIM 4.0 requires a significant investment in technology and training.
  2. Complexity of use: BIM 4.0 is complex and requires specific knowledge, which can make familiarization time-consuming and costly.
  3. Data security: When storing project information in the cloud, data is potentially vulnerable to cyberattacks, which is why comprehensive security measures are necessary.

Expert comment: According to a study by the European Construction Council (EBC), 60% of construction companies are willing to invest in BIM 4.0, but see data security as the biggest challenge.

BIM 4.0 promotes sustainability in the construction industry and helps to use resources efficiently.

Material savings

Detailed planning and material costing minimize the production of surplus material. Architects and engineers can use BIM 4.0 to calculate exact material requirements and avoid waste as early as the planning phase.

Energy efficiency

BIM 4.0 supports energy-efficient construction methods. Simulations can be used to design buildings in such a way that they are operated with minimal energy consumption. The system also ensures that energy is used efficiently during building operation, e.g. by automatically adjusting heating and lighting.

Optimizing the life cycle

With a digital twin, maintenance work can be planned in a targeted manner, which extends the service life of buildings. This conserves resources and reduces the ecological footprint.

Sustainable construction projects: A construction project in Amsterdam used BIM 4.0 to construct an energy-efficient office building. Optimized ventilation and intelligent lighting management enabled the building to be certified as a “green building”.

Developments in the field of BIM 4.0 will continue to accelerate. Some promising approaches could further change the construction industry.

  1. Advanced data analysis through AI: In the near future, AI could be integrated even more deeply into construction planning by making precise predictions about building materials and their service life.
  2. Automated construction sites: Drones and autonomous robots could increasingly take over tasks on the construction site, such as checking construction progress and transporting building materials.
  3. Virtual collaboration on a global level: New cloud and blockchain technologies are making collaboration across national borders easier and more secure.

Innovation view: A pilot project in Japan is already experimenting with autonomous robots that assemble components and correct defects based on BIM data. Such solutions could significantly change the construction industry.

BIM 4.0 has the potential to revolutionize the construction industry. With the integration of real-time data, the use of the cloud and AI and the ability to digitally record the entire life cycle of a construction project, construction processes will become more efficient and sustainable. Companies that adopt BIM 4.0 at an early stage will increase their competitiveness and be able to create modern, resource-efficient buildings.

Final thought: BIM 4.0 is not just a technological update, but a new way of building. Those who invest today are shaping the future of architecture – and ensuring a construction method that takes equal account of the needs of people and the environment.
