Holiday House Hamptons is fast becoming a major fundraiser on Long Island’s South Shore to benefit The Breast Cancer Research Foundation. The second annual edition will open at the historic Watchcase, Sag Harbor on June 29 and run through August 10, 2014. Fendi Casa is broadly publicizing the show house with window displays curated by Holiday House Hamptons’ designer Campion Platt, on view at the New York flagship showroom from May 7 through July 31. The three vignettes, titled Oasis, Ocean and Opulence, are inspired by the showhouse’s theme of “Luxurious Summer Fun.”

“The [Holiday House Hamptons] designs are always edgy and push the envelope just like the research foundation,” says Platt, expressing enthusiasm over the house’s spirited approach in shining light on designers while supporting a good cause. Top interior designers will join honorary chair Steven Gambrel and co-chairs Mary McDonald, Thom Filicia and Vicente Wolf in creating holiday-themed living spaces in the newly restored residences: an open loft, a bungalow, and multi-level townhouse.

Watchcase is the first resort-style luxury condominiums in the Hamptons with interiors designed by Steven Gambrel, a Sag Harbor resident. The former watchcase factory, built in the late nineteenth century, is currently under restoration by the developer Cape Advisors and architects Beyer Blinder Belle, a firm lauded for its sensitivity to historic landmarks of which Grand Central Terminal is a penultimate example.

Kicking off the show house festivities in Sag Harbor is the Opening Night White Gala on June 28 co-chaired by Christopher Hyland and Iris Dankner, the founder of Holiday House, which originated in Manhattan. Hyland says, “Ms. Dankner—an interior designer and cancer survivor—wanted to galvanize the design industry to help fill a void. In our first year in the Hamptons we raised $500,000, a sum we expect to better.”

Designers for the 2014 Holiday House Hamptons include: Bjørnen Design; Brady Design; Campion Platt; Dale Cohen Studio; Elizabeth Dow Home; Elsa Soyars Interior Design; Huniford Design; Milly de Cabrol LTD; Scott Formby; Studio MRS; Tamara Magel Home; Thom Filicia; Vicente Wolf; West Chin Architect.
