Who are we ?
A pioneer in the Swiss construction industry for over a century, Losinger Marazzi is known for its innovative approach. From the initial concept to the operational phase, the company offers sustainable solutions across the entire value chain of a building project. The high-quality homes and workplaces that we develop and build are designed with the needs of current and future generations in mind, ensuring the long-term viability of our customers’ commitments.
Losinger Marazzi has been committed to sustainability for more than two decades, helping its clients achieve their environmental goals. Optimal surface design, the use of recyclable building materials that limit embodied energy, sustainable energy concepts and the protection of biodiversity increase the attractiveness of buildings, neighbourhoods and regions while reducing their carbon footprint. For us, urban regeneration goes well beyond simple energy-efficient refurbishment. It involves intelligent densification and the enhancement of the existing building stock.
Our commitment and the expertise of our employees enable us to deliver innovative and sustainable solutions for our clients and society. With its strong local roots, Losinger Marazzi can also draw on the strength of its membership of the international Bouygues Construction group.
