On June 1, 1950, Jakob Toller founded the Toller company based in Meilen. The company offered paving and rolling work. In addition to communities and building authorities in the area, Jakob Toller quickly gained the trust of other companies. Kurt Loher took over the company in 1983 and not only founded Toller & Loher AG, but also continued to expand the company over the years. From the beginning of 2018, Kurt Loher took a back seat. He handed over the mandate of Chairman of the Board of Directors to his son Henry Loher and the full management to Bruno Ragnacci. The latter has been with the company for over 30 years. At the end of 2020, Kurt Loher passed away after a short, serious illness. For almost 40 years he held the scepter of Toller & Loher AG. Allen appreciated his professional and human qualities. He personally hired and promoted many of our employees. We will protect his memory and continue to run the company in his spirit. On May 1, 2022, Bruno Ragnacci handed over the management to Marco Hirzel for health reasons. Bruno will continue, with his uncomplicated and natural way, as a calculator and site manager, to incorporate his specialist knowledge from his many years of professional experience. In addition, he supports Marco Hirzel with his wide-ranging experience with words and deeds.

I graduated in 1988 from the former STS, now known as SUPSI, receiving the Maraini and Schindler awards for the highest grades. From 1988 until '93, I worked for several architectural firms in Canton Ticino. In 1993, at the age of 28, I decided to start my own practice. Over the years, I have completed numerous projects, the vast majority for private clients, including single-family homes (new builds or renovations), duplexes, apartment buildings, as well as some public establishments such as bars and shops. I personally oversee the work from design to building delivery. I also provide real estate appraisals for banks, public entities, and private clients. Additionally, I offer project management services for third parties. The decision to open my own studio has proven successful, as it has allowed me to enjoy the freedom that independence offers – freedom of time, choices, opinions, and ideas. During these years, I have developed excellent working relationships, and later friendships, with many individuals. I'm referring to my collaborators, craftsmen, and also my clients, with whom I have remained in contact even after the completion of projects. Despite the undeniable challenges, being an architect is a beautiful profession that I pursue with pleasure, enthusiasm, and professionalism!
