Residential Architecture

Feldman Architecture is expanding in Northern California’s wine region


Cedar cladding and large expanses of glass can be seen in a weekend home called Sonoma Wine Country, which was enlarged by American studio Feldman Architecture.

The project is located in the town of Healdsburg in Sonoma County, in the heart of Northern California’s wine region. It is set in a 16 acre estate with beautiful views over the grounds.

The original house, completed a few years ago, was designed by San Francisco-based Feldman Architecture – and the studio was tapped to expand the residence.

“The second phase of design at Sonoma Wine Country works to transform an effortless one-bedroom retreat into a dynamic escape for a growing family,” the team said.

The house was originally composed of two perpendicular bars, which formed an L-shaped plan. A wing running east to west contained a garage, media room, and bedroom suite; a wing running north to south had a shared space for cooking, eating and lounging.

For the extension, the architects added a central volume and extended the east-west bar into a T-shaped house. It now totals 3,634 square feet (338 square meters).

The kitchen was moved to the central volume. The kitchen is designed to flow out onto a rear terrace and is suitable for family meals and larger gatherings.

A sleeping volume – containing a sleeping area, study and bathroom – has been added to the east side. The new volume overlooks a meadow and opens onto a terrace with a fire pit.

“The graceful addition seamlessly extends the home’s private wing to the east, adding an updated, secluded primary suite with views of the valley and distant hills,” the studio said.


The recent project also included the creation of a free-standing studio for yoga, pilates and media rendering. The 41 square meter studio is close to the main house and acts as a “calming hideaway tucked away in a wooded forest”.

The new additions continue the home’s existing vocabulary with barn roofs, dark cedar siding, and ample glazing. The interior finish consists of plaster walls and concrete floors.

The house is intended to provide a strong connection to the landscape.

A notable feature is a series of four oversized counterbalanced glass doors in the great room, which were created as part of phase one. When opened, the doors spill the room onto patios, providing “comfortable outdoor living in both hot and cold weather.”

Founded in 2003, Feldman Architecture has designed numerous residential projects in California and beyond. Others include a Santa Cruz beach house clad in salvaged wood and the renovation of a “quirky round house” on a hill near Silicon Valley.
