Who I am and what makes me thrive.
Dipl.-Ing. Katja Johanna Kammerer, B.A.
Construction professional and passionate creator of living spaces.
Creative
The joy of design and creation has accompanied me ever since – both in my education and in my work in project development, I have continuously dealt with interior design and architecture.
Experienced
In the past ten years, practical construction site experience as a project manager in Europe – from Poland to the Netherlands – has been added. This holistic expertise in the industry shapes my view of spaces – from the unusual detail to flawed execution.
Solution-oriented
Through many years of project experience at home and abroad and leading various project teams, I am used to reacting quickly to unexpected situations and making well-considered decisions.
I value open and appreciative communication and am convinced of using it as a strategy for problem solving.
Supportive
I now want to bring these skills into the private real estate business. I am convinced that my many years of built-up expertise can be a valuable aid for real estate buyers without the corresponding specialist knowledge.
My career stations:
- HTL diploma in interior design and furniture construction with carpentry training
- Bachelor's degree in interior design at New Design University
- Diploma in architecture at TU Vienna
- Management of architecture projects in a renowned architecture studio
- Successfully completed qualification examination for licensed civil engineering in architecture
- International project experience and leadership roles in the architecture and real estate industry
- Head of the interior design department of a Europe-wide active real estate developer
- Technical overall project management of an innovative timber hybrid high-rise building in Germany (see newspaper article)
Privately, I enjoy being active and spontaneous – whether in the mountains or in the workshop. I bring this energy with me into my workday as well.
I have been passionate about woodworking to this day, and my hands-on approach also influences my design. I consider every detail in terms of functionality, durability and cost-effectiveness. In discussions with the executing companies, I know what I am talking about and can quickly build trust enabling us to collaboratively develop the best solutions for a project.
For me, quality of life arises where spaces radiate warmth and personality and are designed to meet the needs of their occupants . The greatest joy for me is when people have found their very personal living space and fill it with life.

Since the apartment purchase was our largest investment and we had little experience, the support from Ms. Kammerer was immensely valuable. She competently accompanied us from the first viewing to contract signing, identified defects that saved us a lot of money, and helped us negotiate confidently with the developer. Thanks to Human Spaces, we felt secure and well advised – we would hire Ms. Kammerer again anytime and recommend her without reservation.

Katja Kammerer helped me greatly in understanding my rental agreement for my commercial premises in 1210 Wien. She gave me valuable tips on how to best discuss unclear issues with the landlord before signing the contract. Through her support, she alleviated my existing doubts, and I was able to approach the conversation with the landlord confidently and self-assuredly. Once all questions were clarified, I was able to sign the contract without hesitation.

Katja Kammerer greatly facilitated the viewing of my potential condominium. With her expertise and empathetic manner, I could fully focus on how I felt in the apartment while she handled all the important technical details. Even afterward, she was there to support me with advice and assistance in making this important decision. I can sincerely and warmly recommend her and only wish I had met her sooner.

"I always felt well taken care of during the apartment purchase."
When purchasing our new apartment, Ms. Kammerer's support was invaluable: she identified defects early and actively assisted us in providing feedback and handling the sometimes difficult negotiations with the developer. This greatly relieved us and gave us a lot of security. Today, we are very happy in our new apartment – thanks in large part to her.

Since I had no experience in this area, I was very glad that Katja Kammerer provided me with advising support during the renovation of my old building apartment.
Through her insider knowledge, I knew exactly what to pay attention to in order to realize my ideas. She will also be my first contact person for future projects.

Someone who wants to make an investment in a property in the future is either an architect themselves, a "real estate guru," or has a trustworthy person by their side who understands the topic and provides professional advice. If this is not the case, and if one does not want or cannot invest the time and effort to familiarize themselves with topics such as building structure, real estate purchase, and sales, then for practical, time-saving, and economic reasons, they will certainly choose the professional Katja Kammerer. She compensates for amateur "knowledge," brings up topics and suggestions for which one might have blind spots or simply lacks imagination and creativity. Above all, she is the advising guardian angel for property seekers to prevent wrong decisions and/or bad purchases.
