Glass Marvel in Earthquake Country

A skillful blend of rural vernacular with modern sensibilities transforms a concrete barn into a unique mixed-use compound set in Sonoma County vineyards.

Hold Steady

The decrepit Geyserville structure was practically falling down when Jensen got the assignment to give it new life. The designers respected the existing heavy concrete walls, adding a layer of rigid insulation inside, along with a layer of “shotcrete” for structural stability. In essence, the design inserts a brand-new building inside the existing one.

Lighten Up

The contrast of old and new, solid and transparent, was key to Jensen’s reimagining of the old concrete prune packing plant. Frameless glass walls now fill the interior with natural light and views of the surrounding vineyards, and large cuts in the existing walls capture even more vistas. The glass is hanging, clipped on the top and placed in “shoes” on the bottom.

Making Peace with Mother Nature

A new concrete elevator core supports the whole structure, letting the building move like a tree in an earthquake. Jensen installed a new plinth to raise the floors above the 100-year-flood level. An added benefit of the new plinth: better views of the picturesque landscape.

Work + Art + Life

The new building is a 21st-century live-work space that’s harmoniously in tune with Sonoma’s agricultural traditions. The downstairs is open commercial space for lease, ideal for hosting any number of events, and the upstairs features three loft areas, including an office for the client, a private residence, and guest quarters for visiting artists.
