Our history

How did it all start?

It all started over 50 years ago with the founding of a craftsman’s workshop in Bad Berleburg. Commitment, passion and persistence made OTTO constantly expand not only the scope of its services, but also appear in many new places around the world. We started our activity in Poland over 15 years ago. From the very beginning, Otto focused on the highest quality of services, dealing with more and more ambitious projects, above all on the Polish market, but also throughout Europe.


In 2019, we celebrated 15 years of presence on the polish market. Each day of our business is an investment and a chance for development. The historic moment of 15th anniversary of presence in Poland was an opportunity for us not only to sum up our work so far, but also to adopt ambitious plans for the future. 2019 also saw an important event for us – we joined the structures of the French Engie Group.

Time constantly brings changes – we have become part of an even larger group, which makes our substantive, competence and financial base even more impressive.
