STONELINE is a working group, which is dedicated to constructing natural stone buildings in the traditional way of dry stone walling. Our field of work involves both new buildings and renovations. Stoneline is mostly active in the private sector of horticulture, but also carries out orders from cantons and municipalities. Owing to the experience of many years, consultation and planning became important components of our work, especially when it involves larger buildings. A further field of activity lies in the training of apprentices, gardeners, municipality workers and interested people in general.
