Born in The Potteries, Staffordshire, to an Anglo-Swiss father and Brazilian mother, Hamrei began to hone his eye for interiors and design between the British countryside and summers spent in the Mediterranean. Following his studies in Architecture he switched to interiors & furniture design through the formative guidance of Gisbert Pöppler in Berlin. Returning to his home country he continued to develop his sensibility for materials and colour during 3 years at Peter Mikic before going on to join French designer Pierre Yovanovitch. Whilst managing projects in the UK and US for the French firm, he continued to develop his own style until he set up his own interior & furniture design studio in the Summer of 2021.
