We live "one and one is three". Together with our clients, we create buildings that put people and their needs at the centre. Working with our clients as equals and in constructive cooperation is particularly important to us. With Jean Erich Treu (Cobra Immobilien), a residential building with 2 staircases and a total of 10 flats is being realised. Michael Pitsch: I value Jean-Erich Treu as a client with a lot of experience who knows exactly what he wants - but also takes advice from experts. Jean-Erich Treu: I've built a lot in my life and I can say that Hawlik Gerginski does a very good job in planning. The cooperation is excellent and I have taken Mr Pitsch in particular to my heart.
