4.0 Wine Cellar

Fredericksburg, Texas

4.0 Wine Cellar required space for a tasting room, outdoor pavilion and wine storage facility. Durable, unmodified materials such as stone, wood and metal were used to reflect a “Texas Modern” design. An expansive roof, visible from a nearby highway, demanded high performance material that would limit reflection to drivers. Fabral Thin Seam and Hefti-Rib metal panels in Slate Gray, actualized both function and creativity.

Fabral Hefti-Rib panel offered a 7.2″ rib pitch, which allows the best strength-to-weight ratio available on the market. On the building itself, high-efficiency glazing and the increased insulation from the Fabral metal envelope helps the building to stay tightly insulated from outside elements.

Project Details

  • What started out as a small-concept tasting room for three collaborating Texas Wineries, transformed into something much greater in this modern winery
  • 31,000 square feet of Hefti-Rib was utilized for the walls and 7,700 square feet of Thin Seam was applied to the roof

Color Details

Fabral custom color Musket Gray was chosen for the roof to limit the reflection to nearby highway drivers. Standard color Charcoal was chosen to compliment the color of the roof and add to the modern feel of the design.
