This year’s winter auctions in Cologne and Munich promise exciting art moments at the end of the year. As the days get shorter, exciting works of art can be discovered. Van Ham in Cologne and Ketterer Kunst as well as Karl & Faber in Munich are opening their rooms to exceptional works of art from the classical modern, post-war and contemporary periods. This season is characterized by spectacular collection liquidations, rare market appearances and impressive work cycles.

Van Ham in Cologne will kick things off with the Evening Sale on December 3, featuring works from the Classical Modernism and Post-War periods as well as contemporary works. Collectors of Classical Modernism can look forward to works by Max Pechstein, Emil Nolde and Alexej Jawlensky at the auction. Jawlensky’s “View of Murnau” from around 1908 is one of the artist’s first Murnau paintings. The artist discovered Murnau with Marianne von Werefkin in the fall of 1907 on their forays through the foothills of the Upper Bavarian Alps. Van Ham has valued the painting, which shows a view of Murnau’s houses, at 200,000 to 300,000 euros. A particularly haunting work is “Still Life with Mask and Sweater” by Felix Nussbaum, who was persecuted by the National Socialists as a Jewish artist and had therefore been in exile in Ostend, Belgium, since 1935. The still life was created in the Belgian coastal town and is difficult to interpret. But against the biographical background – Felix Nussbaum was murdered in Auschwitz in 1944 – it has an oppressive effect, especially the mask, which is that of a person of color. Collectors of the German artist Gerhard Richter will have the chance to bid for eight works by the artist at the Evening Sale, including both early and later works. A highlight of the auction is the painting “Beautiful Lady” by Andy Warhol from 1984. Warhol had already asked the lady portrayed several times to be allowed to depict her – until she finally agreed. The painting has been in the possession of the sitter since it was created and can now be offered by Van Ham fresh from the market for 300,000 to 500,000 euros.

Day sale and special collections
In July 2024, Galerie Thomas filed for insolvency – an announcement that sent the art world in Germany into turmoil. Auction house Van Ham was commissioned to auction off the insolvency estate. Over 400 works of art will now be auctioned off in several sales, as Markus Eisenbeis reports. Galerie Thomas had been an institution for classical modernism, expressionism and international contemporary art since 1964. On December 4, 17 works will be offered in a live auction. Around 400 works will be auctioned in two online auctions in December 2025 and January 2026. Highlights of the live auction include works by Wojciech Fangor, Leiko Ikemura and Walter Stöhrer. The Online Only auctions, also part of the Thomas estate, include works by Joseph Beuys, Serge Poliakoff and Tom Wesselmann – many without a limit. It is a rare opportunity to find works by these names at lower estimates. This auction impressively confirms that Van Ham has been a good address for insolvency auctions for years: the “Achenbach Art Auction” in 2016 already showed that the Cologne auction house has experience in this field.
In addition to the holdings of Galerie Thomas, impressive photographs from the collection of Anne Maria Jagfeld will also be on offer. The collector and interior designer has built up a photo collection of 900 works, 50 of which will be auctioned at Van Ham on December 4. Anne Maria Jagfeld has a keen interest in fashion and many of the photographs on offer are by fashion photographers such as Helmut Newton, Richard Avedon, Irving Penn and Horst P. Horst. A particular highlight is the photograph “Dovima with Elephants” by Richard Avedon. The model Dovima was one of the most successful models of her time and graced the covers of all major fashion magazines, including Harper’s Bazaar. The work now on offer at Van Ham was created for the August 1955 issue. It shows the model in a black evening dress with a white sash designed by Yves Saint Laurent for Dior between two elephants from the Paris Cirque d’hiver. Prints of the photo are in the Metropolitan Museum and the Museum of Modern Art in New York. Van Ham estimates it at 30,000 to 50,000 euros. Other highlights of the auctions include works by Max Slevogt, Max Liebermann, Otto Dix, Serge Poliakoff and Leiko Ikemura.

Further south, the auctions will take place at Karl & Faber on December 4 and 5 and at Ketterer Kunst on December 5 and 6. Karl & Faber will be presenting two works by Wassily Kandinsky from his time at the Bauhaus. The top lot of the house is the work “Calm” from 1930 by Kandinsky. It will be offered in the Evening Sale on December 4 for 1.1 to 1.3 million. The work, which is exemplary for his time at the Bauhaus, combines colors and sounds – Kandinsky was a synesthete. The influence of the Bauhaus and the artists who worked there is also evident: he lived next door to Paul Klee in Dessau.
Collectors of works on paper will also find what they are looking for at Karl & Faber: One particularly interesting work was by Amedeo Modigliani. The drawing “Cariatide” from 1913 is estimated at 380,000 to 450,000 euros. Several works on paper by Gustav Klimt and Egon Schiele will also be on offer. Paula Becker, who was not yet married to Otto Modersohn at the time, created the work “Seated Child with a Book on his Lap”. What is special about this painting from 1897/98 is that there is another depiction on the reverse: “Pond with Birch Trunks”. Paula Becker created this work on the reverse during her time in Worpswede in 1898. The work is valued at 80,000 to 100,000 euros.
All those who have focused their collecting on the second half of the 20th century will of course also find what they are looking for. An unusual work came from Andy Warhol, who created the so-called “Toy Paintings” from 1982 onwards on behalf of his friend and gallery owner Bruno Bischofberger. This series of paintings was explicitly aimed at children. It depicts wind-up tin toys from Warhol’s collection. The series comprises 128 canvases, each depicting one of the toys, including dogs, pandas, monkeys, clowns, robots or, as in the work now on offer at Karl & Faber, a parrot. In 1983, the works were exhibited at Bruno Bischofberger’s gallery in Zurich – the special highlight: the room was designed like a giant children’s room and the works were placed at children’s eye level – adults had to bend down or squat to look at them.
Ketterer Kunst also has Kandinsky on offer. The work from 1926 came from a private collection in Berlin that had been built up over four decades. The top lot of the auction was by Hermann Max Pechstein. The radical expressionist work entitled “Indian and Female Nude” was completed by Pechstein in 1910 and sold for 2 million at the auction. Andy Warhol’s rare Marylin silkscreen series, which rarely appears on the market in its complete form, also stands out. The series will be offered in the auction for an estimate of 1.5 to 2.5 million. Equally noteworthy is Robert Motherwell’s monumental “Open #184” from 1969, a major work from his pioneering “Open Series”, which is valued at 400,000 euros and impressively marks the artist’s transition to a more minimalist expression.
Overall, this year’s winter season is particularly intense: outstanding provenances, market-fresh rarities and rare collection liquidations combine to create an offer that attracts collectors from far beyond Germany – and makes the last auction weeks of the year a highlight of the art market. Anyone interested in art, market movements and the dynamics of major auctions will experience a rare interplay of tradition, rediscovery and international appeal this winter.

Business intelligence for architects and planners sounds like buzzword bingo, PowerPoint orgies and data cemeteries. But anyone who still believes that the future of building culture can be shaped with a gut feeling and a pencil has not heard the digital shot. Data strategies have long been the central tool for everyone who builds, plans and designs. Whoever masters the data masters the city. And those who continue to plan without business intelligence not only miss the market – they risk disappearing into insignificance.

  • Business intelligence is revolutionizing the planning and management of construction projects in Germany, Austria and Switzerland
  • Data-driven decisions are becoming the new benchmark for efficiency, sustainability and quality
  • Innovations such as AI, big data and cloud platforms are transforming traditional planning processes
  • Smart data strategies are essential to optimize resources and meet regulatory requirements
  • Sustainability reporting and ESG criteria require new skills in data management
  • Digital tools combine technical, economic and environmental analyses in real time
  • The profession of architect and planner is facing a fundamental readjustment of its self-image
  • Discussions about data sovereignty, transparency and algorithm bias are shaping the debate
  • In a global comparison, German-speaking countries are at risk of falling behind digitally – unless they finally have the courage to adopt a data strategy

Business intelligence: from cost control to intelligent planning

For a long time, business intelligence was the privilege of large corporations and real estate developers with too much Excel and too little pragmatism. Today, however, BI is the backbone of all serious planning. What does this mean for architects and planners in Germany, Austria and Switzerland? First of all, it’s no longer just about controlling and spreadsheets. Modern BI solutions transform mountains of data into decision-relevant knowledge. Whether it’s space utilisation, material flows, energy consumption, user behaviour or life cycle costs – everything can now be measured, analyzed and visualized. And not just after the project has been completed, but throughout the entire planning and construction process.

However, the reality in the DACH region is sobering. Many offices are still working with fragmented data silos, incompatible tools and Excel graveyards. While international pioneers have been working with cloud-based dashboards for a long time, people in this country juggle between CAD, AVA, BIM and ERP as if digitalization had only just begun yesterday. The willingness to innovate is low, the courage to transform is rare. This is not only due to a lack of investment, but also to a job profile that struggles to combine creative design with data-driven process optimization.

At the same time, external pressure is growing. Clients, investors and legislators are demanding ever more precise evidence – be it on sustainability, cost-effectiveness or user comfort. Those who are unable to provide reliable data are losing relevance. Business intelligence is therefore becoming a survival factor. As a result, more and more planning offices are developing their own data strategies, implementing BI tools and training their teams in data literacy. But the road is rocky. Between data protection, a lack of interoperability and a shortage of skilled workers, many a project threatens to become a permanent digital construction site.

Nevertheless, the advantages are obvious. With business intelligence, risks can be identified at an early stage, costs can be better controlled and decisions can be made on a more informed basis. This means nothing less than a paradigm shift in the entire planning process. From design to commissioning, every step is accompanied by data. Anyone who refuses to embrace this will be flying blind digitally. Those who understand it will set the pace in the industry.

Business intelligence is thus advancing from a pure controlling instrument to a strategic tool for architecture and planning. It’s about more than just numbers. It is about insight, control and – in the best case – real innovation. And the question: who will shape the future – the one with the best design or the one with the best data?

Artificial intelligence and big data: architecture in the age of algorithms

Hardly any other term is currently used as excessively as artificial intelligence. But in conjunction with business intelligence, AI is far more than just a buzzword. It is the game changer for the entire construction and real estate industry. This is because AI-supported BI systems not only analyse historical data, but also recognize patterns, forecast trends and automatically suggest optimizations. What used to take weeks is now done by algorithms in minutes. Whether space optimization, energy management, user behaviour or maintenance – AI is transforming everyday planning.

Big data is the raw material for this development. Sensors, IoT devices, smart meters, BIM models – they all produce a flood of information. Those who structure, filter and analyze this correctly gain an invaluable knowledge advantage. However, many offices and local authorities in Germany, Austria and Switzerland find it difficult to generate real added value from the flood of data. The technical complexity is high, the interfaces are often proprietary, and data protection slows down many a vision to the level of the fax machine era.

Nevertheless, initial pilot projects are showing what is possible. In Zurich, construction projects are being optimized for sustainability using AI analyses, in Vienna, algorithms are simulating traffic flows for new districts, and in Basel, machine learning models are helping to identify structural damage. The results are impressive: cost savings, time savings and a new quality of planning. At the same time, the fear of losing control is growing. Who decides in the end – the architect or the algorithm?

This debate is not new, but it is becoming more acute due to the growing importance of business intelligence. This is because the danger of the so-called “technocracy bias” increases with every further step towards automation. Without critical reflection, there is a risk that the power of design will shift from man to machine. This is why data governance is the order of the day. Anyone using AI and big data must ensure transparency, traceability and accountability. Only then will the architecture remain what it should be: a formative discipline and not just an example of computing.

On a global scale, German-speaking countries are still lagging behind. While Scandinavia, the Netherlands and Singapore have long been operating AI-based city models and planning platforms, Germany is still in pilot mode. The reason: lack of courage, lack of standards, lack of vision. If you don’t wake up now, you run the risk of being overrun by international developments.

Sustainability meets data: sustainability as a data-driven discipline

Sustainability is the new leitmotif of the construction and real estate industry – at least on paper. In practice, there is a deep data gap between aspiration and reality. After all, sustainable construction can only be proven with reliable facts. CO₂ balances, life cycle costs, material passports, resource efficiency – all of this requires structured, reliable and continuously updated data. This is exactly where business intelligence comes in. It makes sustainability measurable and therefore controllable.

In Germany, Austria and Switzerland, regulatory requirements are increasing rapidly. The EU taxonomy, ESG reporting, the Building Energy Act – they all demand a new level of data quality. Those who do not keep up with this will not only lose subsidies, but also market access. However, many architects and planners are simply overwhelmed. Collecting, evaluating and communicating relevant sustainability data is complex, time-consuming and almost impossible without the right BI tools.

Innovative offices therefore rely on integrated data strategies. They link BIM models with life cycle assessment tools and cloud platforms. They record energy and water consumption in real time, analyze material flows and simulate a wide variety of scenarios. The result: well-founded decisions, transparent communication and real progress in terms of sustainability. Those who work in this way not only gain a competitive advantage, but also actively contribute to reducing CO₂ emissions and conserving resources.

At the same time, the danger of the greenwashing trap is growing. Because where data is misused as a marketing tool, sustainability loses credibility. Transparency and traceability are therefore essential. Real progress can only be proven with open data standards, independent audits and comprehensible indicators. The industry is facing a test here. Those who trust the data can shape the future. Those who rely on glossy brochures and gut feeling will remain in the 20th century.

In the end, the quality of the data determines the quality of sustainability. Business intelligence is not an optional extra, but a duty. It turns vague promises into reliable facts. And it forces the industry to be honest. This is uncomfortable, but there is no alternative.

Technical skills and new roles: What planners need to know now

If you want to plan successfully today, you need more than just an architectural flair. Data literacy, data management and a basic understanding of business intelligence are mandatory. The days when architects were enthroned as lone artists in an ivory tower are over. Today, planners must be able to structure, interpret and strategically use data. This requires new skills, new tools and – yes – new roles in the office.

In technical terms, this means an understanding of databases, interfaces, data models and visualization techniques. Anyone who can use BI tools such as Power BI, Tableau or Qlik will have a real head start. At the same time, knowledge of data standards such as IFC or COBie and BIM-based working methods is essential. If you don’t have your own data strategy under control, you will become a pawn of external IT service providers and software providers. Control over your own data remains the most valuable asset.

But technical skills alone are not enough. A new approach to collaboration is needed. Interdisciplinary teams of architects, engineers, IT specialists and data analysts are becoming the norm. Communication, transparency and the ability to make complex issues understandable are crucial. Those who master this can manage projects faster, more efficiently and in a more targeted manner.

The traditional roles in the office are also shifting. Data scientists, data stewards and digital strategists are moving into architecture firms. They develop data strategies, define KPIs and ensure the quality of the information. At the same time, responsibility for data protection and data security is growing. Those who slip up here risk fines, loss of reputation and the trust of their clients.

The industry is at a crossroads. Either it accepts business intelligence as an integral part of the job description – or it leaves the future to others. The choice should be clear.

Debates, visions and the global stage: Quo vadis data strategy?

Business intelligence is not an end in itself and certainly not a technocratic gimmick. It is the central battleground of the future – for planners, architects, engineers and building owners alike. But how is it being discussed? Between the poles of data optimism and data protection paranoia, between digital euphoria and analog inertia. Some see business intelligence as an opportunity for transparency, efficiency and sustainability. Others fear a loss of control, surveillance and the loss of creative design.

The international debate has long since moved on. Data-driven planning platforms are standard in the USA, the UK and the Netherlands. There, data is shared openly, used collaboratively and deployed for innovative business models. In Germany, Austria and Switzerland, on the other hand, the fear of losing control still dominates. Yet openness is the key to real innovation. Sharing data creates networks. Those who hoard it remain isolated.

Visionaries are therefore calling for a new data culture. Open data, open BIM, collaborative platforms and transparent algorithms are intended to democratize the industry. At the same time, critics warn against the commercialization of planning knowledge. Who controls the data? Who owns the findings? What happens if algorithms discriminate or set the wrong priorities? The answers are open – but they urgently need to be found.

Business intelligence is not a fad, but a paradigm shift. It challenges the architect’s self-image, forces reflection and opens up new opportunities for quality, sustainability and participation. Those who ignore it make themselves superfluous. Those who shape it can shape the future of building culture.

Global competition is not taking a break. Anyone who hesitates now will be overtaken by others. The time for excuses is over. Now it’s all about attitude, strategy and the courage to try something new.

Conclusion: Those who have the data are building the future

Business intelligence is more than just another tool in the digital toolbox. It is the key to transforming the construction and planning industry. Data strategies determine efficiency, sustainability and competitiveness. The German-speaking world runs the risk of being left behind if it does not finally find the courage to embrace data-driven planning. Architects and planners must acquire the necessary technical knowledge, think in an interdisciplinary way and understand business intelligence as a central element of their profession. Those who develop the right data strategies today will not only design better buildings – but the city of tomorrow. Everything else is a dream of the future.
