I start from a premise: spaces profoundly influence our balance, even when we are not aware of it. I work and design following the principles of living well-being according to the protocols of Ambient Therapy®, which integrates light, colour, materials, acoustics and sensory perception to create environments capable of regenerating body and mind, in dialogue with neuroscience and the psychology of living. In this approach, a fundamental role is played by unconscious wellbeing: that set of environmental stimuli that act below the threshold of awareness - a light that is not glaring, a muffled sound, a reassuring texture, a temperature perceived as natural - and that determine a profound sensation of security, calm and belonging. Applying this methodology to the world of hospitality means designing each environment - from the room to the lounge, from common areas to service spaces - as an ecosystem of well-being. Light accompanies the circadian rhythm, materials promote comfort and familiarity, acoustics protect tranquillity, spaces support balance, relaxation and sociability. It is through unconscious wellbeing that guests perceive a place as welcoming even before they understand why. In this sense, my experience in the renovation of a Grand Hotel and the historic spa of the 1920s was a precious moment: it allowed me to observe how targeted design choices can transform a stay into a regenerating experience, acting not only on visible comfort, but on the deeper sensorial dimension. Today I can propose concrete tools - an approach, a protocol and methodologies centred on living wellbeing - capable of transforming even transitory environments into places that welcome, regenerate and leave an indelible memory. Design does hospitality to the extent that it truly takes care of the guest, even at a subconscious level, focusing on his or her equilibrium and promoting psycho-physical and social well-being.
