about us.

UBM Development creates real estate for Europe’s top cities. The strategic focus is on green building and smart office in major European metropolitan areas like Vienna, Berlin, Munich or Prague. With over 145 years of history, UBM is a one-stop provider for the entire development value chain from initial planning all the way to marketing. The company’s shares are listed in the Prime Market of the Vienna Stock Exchange, the segment with the highest transparency requirements.

A syndicate comprising the industrialists Ortner and Strauss holds an investment of roughly 39% as the core shareholder. The Executive Committee, an expert board of 20 UBM managers, has invested €5m in UBM shares.

The headquarters of UBM Development AG are located in Vienna. Together with its subsidiaries, the company has also established an efficient network in Central Europe. Strong local integration and wide-ranging market expertise support the timely identification and utilisation of market opportunities which, in turn, protect the future pipeline. UBM’s interdisciplinary team develops ideas for new projects and innovative usage concepts, and also brings wide-ranging interests and users together. We offer a complete range of services required for this integrated approach from a single hand: market analysis, project development, planning and project management, financing, rental and asset management. Specialists with many years of professional experience accompany these processes from the initial project idea up to the transfer to tenants or the final investor. With this know-how, we cover all phases of the real estate value chain internally.

In addition to real estate development, UBM is also active as a hotel lessee. The subsidiary UBM hotels Management GmbH was founded in 2016 to bundle the operational know-how for hotel management and to combine all UBM hotel leasing operations.

UBM Development is sticking to its strategic positioning and is concentrating on its very own core business – real estate development. In addition to a clear focus on top metropolises and three asset classes, UBM is pushing the shift to green and smart buildings. In terms of sustainability, UBM is striving to become the leading timber construction developer in Europe. In addition, UBM always keeps a clear eye on the risk and return profile of the project portfolio in order to deliver sustainable and consistent returns.

All projects that UBM develops have an impact on the ecological conditions on site and thus also influence the climate. That is why we focus on environmentally friendly, innovative and energy-saving solutions from the design stage and realization to utilization and revitalization. Green building is already a tradition at UBM and has been validated by internationally recognized building certificates for many years. The focus on sustainable project development has gained particular importance as a result of the Corona pandemic, and UBM has set itself the goal of becoming the leading timber construction developer in Europe. In order to achieve this goal, UBM already has groundbreaking projects in progress. Coupled with sustainable energy generation and use, we can significantly reduce CO2 emissions over the entire life cycle of the projects. UBM’s buildings are thus part of the solution to achieve the goal of climate neutrality of the “EU Green Deal” by 2050.

Smart buildings are like smart people: they think for themselves. For UBM, this means that buildings can adapt individually to the user experience while at the same time operating as efficiently as possible. By using sensor technology and automation, we can also implement the idea of sustainability here by reducing operating costs. UBM sees the use of technology as an opportunity for project developers, investors and users, as innovation in the construction and real estate industry brings benefits for all stakeholders. Our buildings can be recognized by the new UBM standard, which implements and develops our commitment to sustainability through technology.

and more.
The atmosphere and aesthetics of each building make it more than an office or an apartment. We succeed in designing work and living spaces by telling a story with each project. Inspired by the project surroundings and the history of the respective properties, coupled with the many years of experience of our interior design team, we create distinctive buildings and neighborhoods for living, working and relaxing. With this, we create something “more” that can be felt throughout the project.



Distinct accents create a profile
UBM focuses on European metropolises such as Vienna, Berlin, Munich or Prague. Around 40% of the investments are to be made in each of the top cities in Germany and Austria and around 20% in other markets. We will continue to focus on the three asset classes of residential, office and hotel. We develop entire city quarters and extraordinary properties in prime locations. From planning to marketing, UBM offers all services from a single source.

Strict risk minimization
Strategically, the focus of our business activities is on minimizing risk. This is achieved in several dimensions. In transactions, UBM aims to establish early transaction security through forward sales. At the same time, an “asset-light strategy” is pursued through joint ventures. This enables a broader diversification of the portfolio.

Group-wide standardized processes
From an operational perspective, the aim is to significantly minimize risks by standardizing processes and institutionalizing the 360° approach. In more concrete terms, as part of the “Next Level” efficiency program, all core and support processes were reviewed on the basis of defined “quality gates” and implemented in the entire Group.

Continuation of financial strategy
The focus on a stable balance sheet also remains unchanged. The focus is on four cornerstones: increasing equity, a short balance sheet, controlling net debt, and smoothing the repayment profile. Looking to the future, sustainable financing options are being actively pursued. In 2021, a sustainability-linked bond and hybrid bond were issued for the first time, which were very successfully received by the market.

Dividend policy with continuity
UBM’s dividend policy is based on continuity and reflects the current and future earnings power of the company. For the third year in a row, a stable dividend of € 2.20 was paid despite the challenging market environment in the wake of the COVID-19 pandemic.


clear values.

Competent actions are visible in the sustainable, high quality of all our services. These actions are based on UBM’s history in the construction industry, on our many decades of experience as a developer and on the proficiency of our employees in all technical areas. But we are not only experts in technical engineering, we are also specialists for financial engineering. UBM is more widely diversified than many of its competitors. All types of technical and design issues are in the best of hands with our highly qualified construction engineers, architects, interior designers and facility technicians. The acquisition and sale of properties as well as hotel operations are also managed by UBM’s proven experts. In every phase of our projects, we identify the most important aspects and focus on efficient solutions. We encourage entrepreneurial thinking and independent actions through short decision paths and flat hierarchies. That creates a working climate where everyone feels involved, empowered – and inspired to take action.

Consequent actions are a further conerstone of our self-image. We stand for reliability with handshake-quality. From confidential initial discussions to the first draft and turnkey transfer on time and in budget, every detail gets our full attention. We handle subsequent special requests with exactly the same commitment as an entire project and are pleased when we can exceed our customer’s expectations. Our claim for every project also includes equal treatment for the interest of UBM’s stakeholders and the demands of the market. This is seldom easy but we see it as an obligation for UBM.
Another sign of consequence: Through our commitment and determination, we have grown to become the largest hotel developer in Europe. The share of residential projects is just as large at roughly 40% of our portfolio. In other words, we have consequently placed UBM on a broad foundation tha is also extremely stable. Because a stron balance sheet and sufficient liquidity are important. We address risks carefully in order to also remain a reliable partner for our employees, customers, business associates and other stakeholders in the future.

Transparent or in other words, understandable and predictable actions are not viewed as an annoying obligation, but as an opportunity. UBM’s listing in the prime market of the Vienna Stock Exchange gives us exact, up-to date feedback on our performance. Banks, institutional investors and our project partners are not faced with a black box when they turn to UBM. Through our investor relations activities and our increased media presence, we proactively transport a clear and diverse picture of our company. Our stakeholders and investors can follow UBM’s development, draw logical conclusions and take well-founded decisions.
In the end, this high degree of transparency also pays off for us. It is an essential criterion for our good conditions on the capital market and the substancial confidence of investors in UBM. For example: A bond we have issued in November 2019 with a coupon of 2.75% was oversubscribed in only one and a half hours, and the maximum volume of €120m was broadly placed. This type of favourable refinancing is a major competitive advantage.

UBM was founded on 3 March 1873 as Union-Baumaterialien-Gesellschaft. The company is active in the acquisition and operation of brick factories and quarries. UBM‘s initial public offering takes place on 10 April 1873. In spite of the worldwide economic crisis, the company focuses on expansion in the 1880s and acquires numerous brick factories to become the second largest brick producer in the Austrian monarchy.


At the beginning of 20th Century, UBM holds a 30% investment in the Vienna brick cartel. PORR acquires shares in Union-Baumaterialien-Gesellschaft. High inflation in the early 1920s leads to the expansion of the business model: together with Allgemeine Österreichische Baugesellschaft, a number of residential construction companies are founded in 1921.


In connection with a joint project on the Paris real estate market, UBM and PORR form a consortium at the end of the 1920s. UBM masters the global economic crisis due to its early focus on real estate.


UBM has since left the original business area of Union-Baumaterialien-Gesellschaft far behind and established a new position. In the 1950s, the company increases its focus on project development with a concentration on Austria and Vienna.


After the fall of the Iron Curtain, UBM enters the markets in the Czech Republic and Poland. Several years later UBM is also active on projects in Germany, France and the Netherlands. In 2000, Klaus Ortner purchases his first UBM shares. The entry of the Strauss Group leads to the creation of a syndicate by the industrialists Ortner and Strauss in 2014. The syndicate purchases the majority interest in PORR and separates the construction and real estate activities. The development companies are merged. A capital increase in spring 2015 results in free float of over 60%. PORR’s stake fell below 1% and no longer exists today.


Thomas G. Winkler is appointed CEO/CFO in 2016. The UBM share moves into the prime market segment of the Vienna Stock Exchange. One year later, the smaller Management Board is reorganised according to functional responsibilities – with Thomas G. Winkler as CEO, Martin Löcker as COO and Patric Thate as CFO. In 2018, UBM celebrates its 145th anniversary as a company and completes a rebranding – all subsidiaries now appear under a common brand: UBM Development auf.


The corona pandemic triggered a radical re-orientation to green. smart. and more at UBM in spring 2020. At the same time, UBM set a goal to become the largest timber construction developer in Europe. The UBM Management Board will be expanded in 2021 to include Martina Maly-Gärtner who will be responsible for hotel operations and human resources. In 2023 Peter Schaller becomes CTO and member of the management board.
