[9] In 1985, the Pressman family, who owned Barneys New York at the time, hired Marino to design the women's retail concept for the department store.

"[17] The 56-meter high building incorporated a curtain wall of glass encapsulating a nest-shaped block of aluminum in Chanel handbags’ signature tweed pattern.

[20] In October 2014, Marino designed the flagship store in Seoul, Korea's Cheongdam-dong neighborhood for Boontheshop, a retail brand owned by Shinsegae, a South Korean luxury product specialist.

[24] Marino designed both the building and interiors of luxury Swiss watch brand Hublot’s flagship store in New York on Fifth Avenue between 57th and 58th streets.

[26] Completed in 2018, the 8,800-squarefoot building for Chanel in Istanbul, Turkey, includes offices and a rooftop terrace and is "set back behind an entry plaza of gray marble pavers with a black granite reflecting pool.

[32] Formerly home to the Rogers Memorial Library then the Parrish Art Museum, Marino purchased the 1895 RH Robertson[33]–designed building in 2018 and spent three years restoring the historic façade and transforming the interior architecture.

"[35] Marino’s private collection, on view at PMAF, was acquired over 40 years and ranges from Egyptian, Greek and Roman antiquities to Baroque bronzes, paintings by Jean-Michel Basquiat and sculpture by Les Lalanne, by way of Delacroix, 19th-century faience and the photography of Robert Mapplethorpe.

Changing every season, PMAF's rotating exhibitions[36] have included works Vik Muniz, Anselm Kiefer, Melvin Edwards, Sanford Biggers, Jean-Michael Othoniel and Johan Creten, photographs by Diane Arbus and Priscilla Rattazzi.

"[33] Site-specific commissions by artists Peter Dayton and Richard Woods clad the sides of PMAF's elevator and staircase.

Nicolas Milon of Architectural Digest noted, Marino pays tribute to the history of the House of Dior, he does so by anchoring it in the present.

The contrast between heritage and modernity is expressed throughout the nearly 108,000-square-foot complex, thanks to the combination of more than a hundred different materials, from stone to precious fabrics in a gradation of whites.

[44][45] In December 2015 Marino was sued by Deirdre O'Brien, his former office manager, for allegedly making racist and sexist comments.

[46] In May 2016, Jonathan Michaud, a former textile specialist at the firm, filed a lawsuit in New York State Court, accusing Marino of sexually harassing him and making homophobic slurs.

[47] In March 2018 the American Institute of Architects New York (AIANY) announced that it was rescinding Marino's 2018 Design Awards citing the harassment allegations.

[48][49] According to Curbed, citing a spokesperson for Peter Marino Architect (PMA), the sexual harassment suit was resolved, while a countersuit was filed against the other claimant.
