Through Berenson, Pinsent gained access to a rich clientele, drawn from the English-speaking community in Tuscany.
His clients included Charles Alexander Loeser, Charles Augustus Strong; Mrs Alice Keppel; Lady Sybil Cutting and her daughter, the historian Iris Origo.
At Brdo Castle near Kranj, Pinsent created the gardens' baroque screen.
During this time in Italy, he worked on the restoration of villas and gardens damaged by the War.
