Domenico Mazza was born in Aosta on 12 December 1971. He grew up and lives in Courmayeur, breathing the mountain air and nurturing an interest in the landscape and buildings from when he was very young. He attended a technical college for surveyors in Aosta and, while studying, worked as an apprentice designer for various architectural firms in Courmayeur. After graduating from the Faculty of Architecture at the Polytechnic University of Turin, he practised as a freelance architect and set up his own business at the foot of Mont Blanc.

This successful professional decision led him to working with various architectural firms on projects of considerable importance, such as residences in the Arab Emirates and mountain hotels and villas in Italy and abroad (France, Mexico), mainly investing his energies in the modern reinterpretation of traditional mountain architecture. His company, Work In Progress, mainly deals with small and large projects for private clients who want their home to have an original, personal design.
