The Alexander Valley, Healdsburg, California
When Eugene A. Silva Architect was first contacted by David
Elliot, Winemaker and General Manager of Lancaster Vineyards
Inc., wine caves were being constructed at the site. The task
was to fit a new winery structure between the newly constructed
cave portals which were to have a vertical height difference
of about 8 feet. The new structure consists of about 10,000 sq.
ft. of enclosed building area with an additional 4500 sq. ft.
of exterior covered work areas. The building was constructed
using an ICF (insulated concrete forming) system which consists
of interlocking polystyrene “Lego” blocks which are
filled with reinforced concrete. After extensive research, ARXX
(formerly Blue Maxx) was chosen to provide the ICF blocks and
the bracing system. The finished walls consist of an interior
surface material, 2 inches of polystyrene form, 8 inches of reinforced
concrete, 2 inches of polystyrene foam and mechanically fastened
exterior cement plaster. The exterior plaster (stucco) and poured
in place concrete walls were stained with an aqueous solution
of ferrous sulfate (iron) for an instant aged effect. Additionally,
control joints were left out of the exterior plaster to encourage
A curved steel roof structure was chosen for the exterior work
areas mimicking the green canopy of the existing oak trees on
the hillside above the winery. The open web steel trusses (tree
branches) were left exposed under the roof and is supported by
stained cylindrical reinforced concrete columns (tree trunks).
