Micol Abigail Lütz, born Antonella Mennuni, is the sole owner of Bau Lütz and leads its vision, research, relationships and concept development.

Her path spans more than forty years of experience across education, pedagogy, art, theatre, cultural and audiovisual production, social research and the design of community activities. Art has accompanied her work since childhood and, over time, became an educational tool, a theatrical and cinematic language and a way of observing space, matter and relationships. Her experience also includes organic and biodynamic agriculture and the management of educational and social activities.

Through the Biofattoria i Sabbioni experience, she contributed to the research, with particular responsibility for its social and educational dimension, working alongside the lecturers and young designers involved. During the same period of her professional history, she coordinated educational and organisational activities at Rocca dei Giorgi, a place of hospitality, culture and social work.

At Bau Lütz, Micol conceives the artistic, historical, social and cultural dimension of projects; she selects research themes, imagines new models of living and develops concepts together with architects and technical specialists. She coordinates people and external relationships and, together with Joshua Lütz, develops project strategies and identities. She does not practise as an architect: her contribution lies in ideation, research, interdisciplinary direction, and the human and perceptual quality of living.

In parallel, she is the founder and President of LVVD Suisse, a non-profit association separate from Bau Lütz, and continues a long-standing career as an author, director and producer in the audiovisual and cultural fields, including through SAM’m Productions and related projects.

She is also involved, with Bau Lütz’s current interdisciplinary team, in the preliminary study and dialogue phase concerning the possible revival of an important international congress centre in Geneva.

Her starting point is the human being. A home must protect and provide light, air, beauty and dignity; allow privacy and connection; welcome different ages and degrees of autonomy; and engage with the climate, landscape, materiality and history of its place. For Micol, good living should not be designed only for a few.

Joshua Lütz, born Joshua Maria Mennuni Pacassoni, works with Bau Lütz in strategy, business, innovation, and economic and financial relations.

His background combines a humanities education, international experience, and an interest in enterprise, technology and communication. He studied in Switzerland and Italy, completed ESL language-development programmes in the United States and also attended courses related to international business.

He has achieved A2 level in French, earned the CP-Secur certificate, and gained approximately two years of professional experience in the security sector in the Canton of Ticino. His training also includes an initial PPL pathway in aviation. These different experiences developed operational discipline, attention to procedures and the ability to manage concrete situations.

At Bau Lütz, Joshua works alongside Micol on the development of project strategies and identities, with particular attention to technology, business, and relationships with economic and financial stakeholders. He contributes to the assessment of opportunities and to dialogue with banks, financiers, investors and potential collaborators.

He participated directly in building Bau Lütz’s digital identity, from creating the logo to developing the website and digital tools. In the preliminary work in Saint-Gingolph, he also contributed to photographic and video documentation, editing and the musical component, helping Micol and Maurizio tell the story of the territory and the concept.

He is co-founder and Vice-President of LVVD Suisse, an association separate from Bau Lütz. In the audiovisual field, he also collaborates with SAM’m Productions and is intended to present the documentary project in development, ‘La Svizzera nascosta’.

Finally, together with Micol, Maurizio, François and Marco, he is taking part in the preliminary phase of the project concerning the possible revival of an important international congress centre in Geneva, contributing primarily strategy, communication, technology and relationship development.

Architect Maurizio Mennuni is the lead reference architect for the Bau Lütz design network. His background brings together architecture, art, spatial representation, digital design and extensive teaching experience.

Educated at the Politecnico di Milano, he worked as an academic subject specialist from 2005 and, from 2009, taught twenty-five editions of the course ‘3d Studio Max per l’architettura’ at the Politecnico di Milano’s Dipartimento ABC. His experience includes design, BIM, three-dimensional modelling and rendering, graphics, audio, video and the production of virtual imagery.

Among his research and teaching experiences, Maurizio was, together with architect Fabio Vanerio, one of the lead lecturers for the work developed with young students around the Biofattoria i Sabbioni: an educational and design pathway that led to research, theses and a publication.

His collaboration with Micol and Joshua predates the current configuration of Bau Lütz. Maurizio accompanied them as their reference architect through several professional phases, including the one connected with MACH Star and Marco Pace, and contributed to interventions and studies in Meyrin and Genthod. He also collaborated on the design of the renovation of Torre Fiorente on Lago Maggiore, working alongside Marco Michelon’s construction work.

He participated in the design development of La Farfalla and in the Villa Coquille preliminary study in Saint-Gingolph. His role is to translate artistic, social and territorial intuitions into space, proportions, volumes, materials and verifiable architectural solutions.

Maurizio’s visual background also reaches beyond the strict boundaries of architecture: he has experience in filming, documentary, television, radio and music programming. He has also worked as a cameraman and audiovisual technician on productions developed with Micol, including ‘Alexandra’.

He is also involved in the preliminary study phase concerning the possible revival of the important international congress centre in Geneva around which Bau Lütz’s current interdisciplinary core is taking shape.

François Bressoud is an architect and building-engineering professional with extensive experience in Valais and French-speaking Switzerland. He is managing partner and president of BF Architecture et Technique du bâtiment Sàrl in Vionnaz, a practice active in architecture, real estate, the transformation of existing buildings and technical expertise related to buildings.

Public professional and institutional sources document a broad and complementary profile. Bemax presents him as an Architecte EPFL active in suivi de chantier; an official report by the État de Vaud and the Ville de Lausanne identifies him as dipl. HES-SO and physicien du bâtiment for BF Architecture. The practice’s public profiles also refer to expertise as an Expert CECB and fire-protection specialist, alongside energy optimisation, diagnostics, and Minergie, Minergie P and Minergie ECO processes.

François combines his professional expertise with significant institutional experience. He served as a member of the Grand Conseil of the Canton of Valais and chaired its Commission for Economic Affairs and Energy. He is currently a municipal councillor in Vionnaz and chair of the board of Energies Nouvelles Vionnaz SA.

His relationship with Bau Lütz began in Saint-Gingolph. François already knew the site on which the team would later develop Villa Coquille, having worked for the previous client on an earlier residential proposal for the same site. Since 2025, the collaboration has become established, with François supporting Maurizio Mennuni through his knowledge of the territory, procedures, French-speaking context, and local technical and energy matters.

For Bau Lütz, François is now the reference architect for French-speaking Switzerland and is also available to work in other cantons when a project requires his expertise.

He is also part of the core team involved in the preliminary study and dialogue phase concerning the possible revival of an important international congress centre in Geneva.

Marco Michelon is a reference site manager, ecological-building trainer and artist within the Bau Lütz network. His path began with technical education and developed through direct construction-site work, natural materials, renovation, landscape and artistic research.

After completing his technical diploma, he pursued university studies in Natural Sciences in Milan for two years and attended oil-painting and ceramics courses. Since 2000 he has specialised in raw earth and Moroccan tadelakt plaster, training with masters in Amsterdam and Roussillon in Provence before carrying out work in Italy and abroad.

He also gained entrepreneurial experience in ecological building through Ecocostruire, a family enterprise connected with construction and the use of natural materials.

Materiality is also central to his artistic work. Lime plasters, earth, oxides and beeswax become pictorial and sculptural media, creating material works in which craft practice and artistic research meet. His work has also been presented in public exhibitions, including ‘Tra l’Incudine e la Cazzuola’ in Castiglione Olona.

Marco also maintains a practical relationship with agriculture, gardening and landscape. His experience includes taking part, with his brother, in the landscaping of the Residenza Vivere Blu in the Ascona area.

His collaboration with Micol and Maurizio began many years before today’s Bau Lütz. Marco participated in the renovation of Torre Fiorente, working on materiality, consolidation and construction elements in dialogue with Maurizio’s architectural project.

Within the La Farfalla model, he was identified as an on-site trainer: the person intended to pass ecological-building techniques and materials on to teams of masons, including young people and adults in combined training and work programmes. La Farfalla remains a model in development; this role must not be described as a construction site that has already taken place.

Today Marco works on a project basis between Italy and Switzerland, mainly on renovations and the rehabilitation of existing buildings. He is also involved in the preliminary phase of the Geneva congress-centre project, where his contribution concerns construction-site work, materials, ecological building and the transfer of skills.
