Revitalize established buildings – do it now to prepare them for tomorrow!

All buildings require regular upgrade of both technical and energy-related systems. This is the only way to preserve the value of your properties. And now is the time to go one step further – with Sustainable Refurbishment!  

Because only those who refurbish sustainably will make their established properties fit for the future. Stricter climate protection regulations and new user needs already require property owners, tenants and operators to act with foresight.   

85% of buildings in the EU are over 20 years old
30% of energy emissions are caused by buildings
80% of energy requirements can be saved through professional refurbishment and the use of modern building services equipment
Only 1% of EU building stock is renovated to improve energy efficiency each year


"Tell me what you’re experiencing, and I'll tell you the state of your buildings.” Of course, it’s not quite that simple, but social developments and personal experience have an impact on behavior – and on what people expect from buildings. Two trends are of particular importance for established buildings: Climate protection and cultural change.

  • The EU aims to make its building stock climate-neutral by 2050. Building renovation is a key initiative of the European Green Deal and has the aim of making the construction and real estate sector more energy efficient.
  • People are changing – and so are our buildings. New generations have different needs for housing, consumption, travel and work. These influence the demand for established buildings, added to this is the experience of the coronavirus pandemic.  

There are four key topics that anyone intending to undertake sustainable refurbishment must address: Digitization, New Work, Climate Efficiency, and ESG (Environmental, Social, and Corporate Governance).

Sustainable refurbishment: It’s up to everyone

Unrenovated properties dating back to the 60s, 70s or 80s already pose huge problems for portfolio holders. Their structural and physical properties lead to high energy consumption and operating costs, making them less attractive for leasing. And often, the design of space no longer meets user requirements. The transparency required by ESG (Environmental, Social, and Corporate Governance) criteria is prompting investors to rethink their investments. Investing in sustainable refurbishment also opens up opportunities for additional sources of income, for example through digital business models.   

We provide portfolio holders with comprehensive and independent advice on courses of action – and this results in sound solutions that are fit for the future.  

Buildings are major cost items for companies. Unrenovated buildings, in particular, are often energy guzzlers. Sustainable refurbishment harmonizes company-specific requirements with economic aspects. Which renovation measures make economic sense? How can carbon emissions be reduced and energy costs cut? What are the benefits of digital technologies? Companies whose core business is not real estate have a particularly high need for consulting services. And we meet this need. We offer owner-occupiers technical and economic know-how from a single source.  

Whether their lease involves office, retail, food & beverage or hotel space, all tenants want to maximize the added value. And we help our customers achieve this by supporting the fitout of their space – from the start of the project, design and planning through to implementation. We also assist operators and tenants with General Construction Management services and our industry expertise. And in the case of office space, we bring tenants and landlords together.


Refurbishment know-how for your industry

Renovate, modernize, revitalize: There’s no one-size-fits-all solution to making buildings fit for the future. Every sector has different challenges. But we are familiar with them all and our experts can offer you sector-specific refurbishment solutions! Do you want to bring a production building into line with current regulations? Renovate a residential building to make it energy-efficient? Or develop a strategy for an aging shopping center? What challenge do you face?

Many production sites have undergone several different modifications over the years. This results in a risk that the usage or building permit is void. Companies in this situation need to act and have their established buildings approved retrospectively. If they fail to do so, their operating license also becomes void.  

But there are plenty of other reasons to modernize established buildings, including shorter product life cycles and changes in the product range. It is also worthwhile for manufacturing companies to take a holistic view of their production site and to plan sustainable refurbishment measures strategically.  


If you have residential real estate in your portfolio, you should make it fit for the future. This involves more than just making the minimum structural and technical investments. If you are intending to sell, a structural or design upgrade allows a higher sale price to be achieved. How does the building stock impact the environment? The ESG criteria and EU taxonomy impose a duty of transparency.  

Densification? Making vacant spaces usable? We develop holistic concepts for residential properties – turning ‘tired’ buildings into refurbished and repositioned buildings with a future.  


Many retail properties suffer from a renovation backlog. This is particularly critical in view of changing customer needs. The shopping experience is important for bricks-and-mortar retail properties. So shopping center operators urgently need a holistic future-oriented strategy. This strategy will be based on the vision of your destination, economic conditions and analysis of the environment. And we offer all these services from a single source! Are the upper levels of your retail property standing empty? Are you planning to repurpose them – for example as apartments, offices or as a hotel? We undertake a feasibility study for you, assessing the various options based on structural, economic and sustainability factors.

With real estate as their core business, property companies have a keen interest in avoiding renovation backlogs and outdated building services equipment. ESG reporting requirements make transparent to what extent property companies meet the criteria for environmentally and socially responsible corporate governance. Buildings with poor energy efficiency lead to high operating and utility costs. Tenants move out – and new ones are difficult to find. In the worst case, a neglected property threatens to become a stranded  asset – in other words, worthless. We support property companies in making their buildings and portfolios fit for the future.


The hospitality industry faces the challenging task of making its properties permanently sustainable for the future. Does the hotel concept have a future? What structural refurbishment measures are necessary to maintain its value and secure the return on investment in the long term? We support hotel owners, operators and investors in developing and implementing sustainable refurbishment strategies for their properties.  


Ever-changing requirements and processes – compounded by fluctuating demand: Companies in the chemicals and life science sectors must implement the necessary complex renovations and conversions in their existing production buildings and laboratories. And they do this with the facilities in full operation. We support our customers in these sectors with the implementation of their modernization, conversion and replacement projects on the basis of state-of-the-art safety standards.
