He approaches every project with careful consideration of its ecological, cultural, and territorial context, ensuring sustainable and responsible development.

Through his professional practice, policy work, and leadership within professional organisations, he has promoted the integration of landscape, ecology, heritage, and urban development. A strong advocate for international cooperation, he has contributed to the exchange of knowledge and professional standards across Europe, helping to strengthen the visibility and influence of landscape architecture at both national and international levels. His longstanding commitment to the profession and his support for the development of IFLA Europe have made him a respected figure within the European landscape architecture community.
