Tradition and Experience
in Real Estate Advising

The Berlin real estate market is our home.

The Kasten-Mann family has been active in the Berlin real estate market since 1954. Kasten-Mann Real Estate Advisors GmbH & Co. KG has its roots in project development and property management founded in 2002.

The success of this owner managed consulting company is due to the Kasten-Mann Gruppe reputation in Berlin and in particular, our roots in the local real estate market are an added value for our clients.

Kasten-Mann is synonymous with efficient prospecting for office spaces, a highly committed team and an exclusive service right up until the rental agreements are successfully signed. Our holistic service approach saves our clients time and money and is what differentiates us from other real estate agents.

Dr. Ehrbeck is the new CEO as of 2017 and will enrich the company's portfolio with her extensive knowledge and experience in office rental marketing in regards to landlord representative mandates. Kasten-Mann will take on medium and large mandates on both the landlord's and the lessee's side. The business segment will be expanded by an investment department with a special focus on buying and selling prime Berlin commercial real estate.

Being the NAI apollo group’s exclusive partner in Berlin, we have one of the world’s leading real estate service agencies behind us. It is 375 branches and 6700 employees strong on a global scale and offers 9 locations in Germany. This gives us the opportunity to offer our clients first class services that extend far beyond the Berlin market.

At the right place
at the right time

New strategies in real estate advising.

We will find the perfect office property for you on time and with minimal waiting time. How do we do this? By utilising our excellent network - and with systematic precision work.

1. Saving time through profiling
You rarely have time to go through a vast number of offers. We will conduct a detailed needs assessment and then present an exclusive selection of the best properties on the market specifically geared to your search profile. Not “approximately” what you are looking for but exactly what you are looking for. We will accompany you to the showing of the properties in a set timeframe.

2. More offers through networking
As established project developers on the Berlin real estate market we are always first to know where new projects are built or old buildings are renovated, which is why our database has significantly more entries than other market players. Our clients are always one step ahead thanks to our excellent contacts with owners, property managers and investors.

3. More quality thanks to investigative research
We put a lot of time into research and into initiative inquiries with owners, which is why we not only know of properties ready for occupancy, we also know when and where premium spaces will become available. The same applies to premium office spaces in prime locations in Berlin as it does to top jobs in international businesses: They are hardly ever advertised. You have to be in the know in order to get them.

Office spaces are rare in Berlin’s top locations.
We will still find you premium properties in highly sought-after locations.

We will give you
the optimum experience

Tenant Representation

Lessee Services

  • Needs assessment
  • Space planning
  • Site procurement
  • Space optimisation
  • Contract management
  • Removals coordination

We will be with you throughout the entire process, and if you wish we can also assist in drafting the contracts.

Maximising quality, lowering costs:
This is how we work for you.

Benefit from our substantial experience and knowledge as project developer and owner: We will review your rental agreement and modification costs for transparency and savings opportunities. We negotiate on par with landlords to get you optimal contract conditions. This is how we capitalise on valuable optimisation potential for your new office real estate.

1. Compiling a needs assessment
Efficiency through structured planning

We will develop a detailed requirements profile based on a structured needs assessment and create ideal space concepts according to your needs. Kasten-Mann Real Estate Advisors will always keep an eye out for the best possible space and cost efficiency for you.

2. Finding ideal spaces
Systematic real estate search

A good network is a key advantage especially in the field of property procurement. Thanks to our excellent contacts we can broaden our search to properties not yet on the market: leased properties where there is a possibility for change in tenancy, as well as current and planned building and renovation projects.

3. Raise space efficiency and lower expansion costs
Our team of planners compares and optimises floor plan options of your favourite real estate and develops a detailed expansion plan for you. We reduce the adjacent areas to a minimum by consolidating spaces without sacrificing ambience. We also make sure that arising refurbishments stay within the budget and check that you are getting the best services with excellent conditions.

4. Negotiating your rental agreement
Reducing costs and risks

You can rely on our expert support during rental agreement negotiations. We will be by your side during negotiations, review your contract for hidden costs and risks and our specialists will critically examine facts and circumstances, insisting on optimum conditions for you.

5. Removals coordination
Organising the perfect start

Organising removal services, delivery date coordination and sequencing are the main components of our removals management. We are also happy to get comparison quotes for you.

Berlin: from tenant
to ownership real estate

The shortage of modern office spaces is on the rise.

In 2010 companies in Berlin were still spoilt for choice with a huge number of high quality office spaces in central locations but the tide has turned. The reason for this shortage is the vast number of rentals by NGOs and associations in the federal capital. Furthermore, a great number of new representative offices and start-ups have stimulated the market.

The fact that many companies have chosen to move from the city’s peripheral areas to locations within the inner city railway ring have also had adverse effects on the availability of properties in the city centre. Vacancy was at a record low of 1.0% in July 2018 and there are hardly any speculative office space building projects on the market.

The shortage in available spaces is especially significant when it comes to modern spaces in central locations in Berlin, especially office lofts but even medium and small sized spaces between 500 and 2,000 Sq M are increasingly rare.
