The House on Sag Harbor exemplifies refined minimalism and profound connection to its site. Designed by 1100 Architect in collaboration with homeowner Kelly Klein, the residence is composed of two intersecting rectangular volumes, with the primary structure oriented parallel to the shoreline to maximize panoramic water views through a dramatic 40-foot glass wall.
The restrained architectural language seamlessly integrates the home with its surrounding landscape, creating a composition defined by simplicity, precision, and material authenticity.
To achieve the home’s minimalist expression, the design team required a highly customized exterior material solution. The façade was intentionally stripped of unnecessary visual elements—including exposed window frames and gutters—making a high-performance wood cladding system essential for creating a continuous transition from wall to roof. Key design priorities included long-term durability, minimal maintenance, and predictable weathering to a consistent, soft gray patina.
The final specification featured a custom SiOO:X wood cladding system, selected for its textured grain and accelerated weathering characteristics that complement the home’s understated architectural aesthetic. An organic preservative treatment further enhanced the material’s durability and resistance to decay.
A custom sliding barn door clad in VETTE shou sugi ban introduces a bold material contrast to the weathering SiOO:X façade. Its deeply charred finish provides a rich visual counterpoint while establishing a deliberate connection to the property’s nearby renovated black cabin, reinforcing the project’s cohesive architectural narrative.
Throughout the design process, the project team worked closely with RESAWN to evaluate material performance and constructability. The architects visited the RESAWN facility to review product samples and observe exterior weathering test installations firsthand.
Drawing from previous roof-cladding projects—including Six Square House and Twin Gables—RESAWN provided installation guidance, technical precedents, and detailing recommendations to support the project’s unique wall-to-roof application.
An on-site mockup was constructed to evaluate weathering performance, refine installation methods, and validate the design prior to full-scale construction.
To support the project’s demanding level of craftsmanship, RESAWN manufactured a custom S3S profile to project-specific dimensions and provided ongoing technical guidance throughout construction.
Support included wall and roof assembly recommendations, installation detailing, and on-site field visits to review construction methods and critical transitions. This collaborative approach helped deliver a high-performing exterior envelope that fulfilled both the technical requirements and the homeowner’s architectural vision.
