Project Detail


William Selyem Winery

Sonoma, CA United States


Project Description

Being the first from-the-ground-up new winery to be constructed in Sonoma County, CA in nearly a decade, the design process for the renowned Williams Selyem winery was complex and demanding. To capture the essence of Williams Selyem’s iconic status within the industry and its place in Sonoma’s cultural evolution, the design had to recognize the winery’s natural and minimalist philosophy while demonstrating Sonoma’s evolving modernization process.

Winery owner John Dyson involved Venezuelan design architect Alex Ceppi of D.arc Group in New York as lead designer. The architect of record for the project was Patrick Mervin Associates, Calistoga, CA.

The administration building, the project’s most public building, uses iconic elements of winemaking as a generator of form and meaning. The building is capped by a cantilevering wood and RHEINZINK barrel-vaulted structure. Approximately 7,700 of RHEINZINK stepped panels, fabricated by MetalTech—USA in Peachtree City, GA, were utilized to create the barrel vault roof. The panels were installed by Architectural Metal, Inc., Hopland, CA. “The flying barrel vault panel system is beautiful,” said Ceppi. RHEINZINK was also utilized for fascia soffit and gutter trim. The sides of the building utilize local redwood and masonry-clad programmatic volumes. The general contractor on the project was Jim Murphy & Associates, Santa Rosa.

RHEINZINK is a titanium zinc, copper alloy with unmatched longevity and elegant appearance, making it an ideal building material for roofing, façade cladding, gutters and interior design. RHEINZINK complements both traditional and modern architecture and due to the material’s natural flexibility, curvilinear surfaces can be clad with ease. We offer even more design possibilities, producing our unique material in four different product lines. The PATINA LINE is the classic of these lines – as it ages its beauty improves over time. The PROTECT LINE has a clear coating providing durable surface protection in aggressive climates, prolonging the initial appearance of the material. With COLOR LINE, a pallet of five colors is now available to augment a project. And with the appealing INTERIEUR LINE, RHEINZINK can be used in the design of interiors. RHEINZINK complies with the strictest environmental standards and is 100% recyclable. The material RHEINZINK has been able to claim the title ‘sustainable’ from production all the way to its permanent application for over 40 years.
