Sustainability Statistics

Leed Gold Certification


  • The design renovated an industrial winemaking facility into a high-quality visitor’s center. Landscape allows the integration of the historic 19th century buildings with a new high performance hospitality and winemaking facility.
  • Soils were amended, and protection zones were communicated to the contractor.


  • Three trees were kept in place at the entry.
  • 185 trees were planted.
  • Mycorrhizal fungi was implemented in the soil mix to provide increased water and nutrient absorption for the planting. In turn, the planting provides the fungi with necessary carbohydrates.
  • Annual planting was avoided.
  • Low-water planting was used on-site.
  • A small organic garden produces cut flowers, organic vegetables, olives, fruits, and herbs.


  • Water is reused for landscape irrigation. All the processed water from the facility, goes to a settling pond, and is then aerated and filtered for reuse.
  • The site design mitigates stormwater runoff.
  • 48% of surfaces are permeable.

Carbon, Energy + Air

  • Trees sequester 22,200 pounds of carbon annually, which offset an average car driving 30,199 miles.**


  • The project provides optimal site accessibility, safety, and wayfinding.
  • The project created a significant number of new program spaces in the garden, allowing for more visitors and activities. This supported increased wine sales.

* The tree average for water interception is 500 gallons. American’s use an average of 100 gallons of water per day (EPA’s water trivia facts)
**120 pounds of CO2 per tree annually (This number is based on an average from the National Tree Benefits Calculator) One car produces an average of 8,320 pounds of CO2 per year. Each vehicle drives an average of 11,318 miles per year. (The Code of Federal Regulations - 40 CFR 600.113)

Hall Wines

A sensitive blend of modernism and tradition, the new and renovated facilities and gardens at Craig and Kathryn Hall’s Napa Valley winery expand their sizable production capability and provide a world-class hospitality destination for their growing brand. OJB worked with the Halls to create a five-acre garden that invites exploration of this beautiful working landscape, accommodates the winery’s many special events, and provides a refined setting for the significant sculpture collection. 

A renovated entry along Highway 29 employs specimen shade trees, exuberant perennial plantings, and a signature sculpture to draw visitors through the working organic vineyards to a new auto court organized around a magnificent preserved valley oak. A straight sightline connects this tree with the main entry to the new Visitor Center. Located along this walk, an arrival court beneath a grove of shade trees serves as a gathering area for winery tours. 

Signum Architecture’s state-of-the-art, 30,000-SF Visitor Center features the Hall’s extensive collection of modern art throughout reception areas, public and private tasting rooms, and a ground level demonstration kitchen that opens onto a dining and event terrace. 

The winery hosts music, culinary, and cultural events on a 6,500-SF Great Lawn adjacent to the renovated Peterson-Bergfeld historic building. At the vineyards’ edge, a gravel terrace with a long granite reflection basin, umbrellas, and lounge chairs affords spectacular views of the Mayacamas Mountains. Low limestone walls divide the northern gardens into discrete rooms dedicated to cut flower production, an organic kitchen garden, and the Olive Grove which doubles as a rotating gallery for art installations.
