[citation needed] He designed a wide variety of projects on the most diverse scales: gardens and public parks, industrial districts, hotels and tourist villages, motorways and agricultural areas.

The hundreds of projects implemented in Italy and abroad comprise the most extraordinary[citation needed] “landscaped” gardens, perfectly integrated within the surroundings and so natural as to appear untouched by human hand.

He met famous plant breeders and horticulturalists (Fritz Encke, Karl Foerster) and the most eminent European garden and landscape architects (Russel Page, Geoffrey Jellicoe, René Pechère and Gerda Gollwitzer).

This dynamic studio rapidly became a benchmark in the cultural life of the city, introducing Porcinai to the influential business dynasties who were to remain his loyal clients throughout his professional career.

In Italy the post-war economic reconstruction produced a new moneyed class of industrial entrepreneurs: manufacturers of televisions and textiles, and executives in the burgeoning empires of petroleum and technology.

From designing private gardens for industrialists it was a logical step to projecting sites for factories and offices: notable examples include the Mondadori centre in Segrate, Milan (in collaboration with Oscar Niemeyer), and the Brion Vega plant in Caselle d’Asolo, Venice.

He was also engaged in large-scale projects such as the new Brennero motorway in northern Italy and the intricate relocation of the Egyptian temple of Abu Simbel for UNESCO.

His remarkable professional expertise ranked him among the elite of European landscape architects, a position consecrated in 1985 when he was the only living Italian to be assigned an extensive biography in The Oxford Companion to Gardens by Sir Geoffrey and Susan Jellicoe.

He contributed to magazines and newspapers (both Italian and foreign) including Domus, Garten und Landschaft, Architecture d'Aujordhui, and other minor journals such as Il giardino fiorito, Flora, etc.
