Uncharted entrepreneurial territory

After many years of experience in the construction industry, the first generation decided to take the step into self-employment. The flair for precision and aesthetics led to the first investment in a watch and jewellery shop.

The proceeds from the watch and jewellery business were used to finance the first properties in Switzerland. The city of Basel thus became the birthplace of our current property network.
