About Us

Kassandra was borne out of our experience with historic environments and a recognition that the transformations required to create long-term resilience – whether in the face of Covid 19, climate change or other emergencies – require bringing together strategic understanding of complex multi-layered data and detail knowledge of the physical environment they derive from.
Cities, new or old, must face the inevitability of change, perhaps even audacious change. Meaningful decisions must interpret meaningful data and inventive and inspired design is the way of ‘managing change’. We believe this approach can turn the risk posed by climate change into an opportunity to engender a new sustainable urban design approach and renewed architectural aesthetic.
Cities can, with the right decisions and a renewed sustainable partnership with Nature, continue their dialogue with time, purpose and aspiration. They are marks of life and place. And they can still have great possibilities.



Mark Cannata established his architectural practice, Zero Zero, in 2013 with Francis Scott in New Zealand and opened the Italian office in 2015. Prior to moving to New Zealand, Mark was Head of Culture and Heritage for Europe, Middle East and Africa at HOK in London. He previously led the Historic Buildings Unit at John McAslan + Partners and worked for a number of Conservation practices in the UK and design practices in Italy.

Mark has been responsible for the delivery of a large number of projects that often involve careful interventions in historic contexts, such as London’s King’s Cross Station and the De La Warr Pavilion – one of Britain’s most important Modernist buildings. He has also overseen innovative design proposals for high profile projects internationally, including the reinvention of the BBC Maida Vale recording studios and the creative re-use of seventeenth-century Franciscan convent ruins to house the new Museo Archeologico Ibleo in Ragusa, Italy. In New Zealand Mark was responsible also for the Built Heritage Technical Expert Report for the Auckland City Rail Link, which assessed the impact of the project on central Auckland’s Heritage.

Mark has been a visiting examiner and lecturer at several schools of architecture in the United Kingdom including Nottingham, Kingston, Leeds Metropolitan and Cambridge Universities. In New Zealand, he was a professional teaching fellow at Auckland University’s School of Architecture, responsible for third-year design studios focusing on Heritage. His articles and research papers have been published in numerous conference proceedings and books, most recently in James Stirling and the Red Trilogy and The Cultural Role of Architecture.
Mark is currently a member of the Twentieth Century Society, the Society for Protection of Ancient Buildings and a committee member for the UK of Europa Nostra, the pan-European Federation for Cultural Heritage Organizations.

His focus is combining Sustainability and Heritage: he has been for many years an Architect accredited in building Conservation and is also a LEED AP®️ BD+C.

Antonio Stornello opened his architecture studio in Modica, Sicily, in 2003, choosing to take an innovative and highly sensitive architectural approach within what is an important historical architectural environment.

He has been responsible for the design and delivery of several alterations, reuse and Conservation projects in many of the historic centres Sicily and innovative new buildings within the residential, commercial and in the hospitality sectors. Drawing inspiration from his travels, Antonio has been recognised for an approach based on careful balance between design and functionality and between scenography and architectural invention.

His particular interest in Project Management has allowed him to master the contemporary Architect role as design manager and chief coordinator between all stakeholders, on one hand, and develop a unique approach to Construction Management and the management of work flow via Building Information Modeling, now an indispensable tool in the design and delivery process.

Antonio is a member of the Project Management Institute – Sicily Branch and since 2017 he has been a councillor of the local chapter of the Ordine degli Architetti of Ragusa and councillor of the Architectural Foundation of Ragusa which organizes conferences, exhibitions and talks relating to the theme of reuse of the urban centres, often involving internationally renowned architects.
