"We, the management of LEONHARD WEISS, direct the family enterprise in a passionate, goal-oriented approach in accordance with company values. We hold one another in esteem as partners. Leading the company as a team has been a tradition for us since our founding in 1900. In the process, we promote and demand the strengths of each individual employee.

The established structures in the family-led company have retained the principle of quick decision-making, a streamlined and flexible organisation, as well as independence from banks in what is now our fourth generation. Based on this success story, LEONHARD WEISS, a complete provider of construction works, is now one of Europe’s leading construction companies.

Our company culture is characterised by advanced thinking and action. New ideas and comprehensive knowledge keep us and our customers continuously heading in the right direction. Many customers have already chosen LEONHARD WEISS as a collaborative and trusting partner over decades. Our value-oriented ambition is the enduring satisfaction of our customers with our daily work. Having customers that recommend us is our goal. All for one reason: To experience the joy of construction!"
