Blurring boundaries between inside and out

Balancing refined design with everyday livability for a modern Hillsborough estate.

Modern Hillsborough Estate is a ground-up residence set on a prominent corner lot in Hillsborough, replacing a small, constrained home with a refined, contemporary retreat, reworking massing, circulation, and site relationships to better connect with its setting. Defined by clean lines, flat roofs, and expansive glazing, the redesigned two-story home balances architectural clarity with warmth and livability. Natural coursed limestone, wood rainscreen cladding, and metal accents create a rich, layered material palette. At the heart of the home, a spacious family kitchen is complemented by a separate catering kitchen, supporting both everyday life and large-scale entertaining. Indoor-outdoor living spaces open to a reimagined pool and lounge area, while a pergola-shaded breezeway links the main residence to a detached guest house and family gym, completing a cohesive, modern compound.

“This is an absolutely exquisite use of an existing century-old hay barn. A daring and whimsical insertion of mirrored, conditioned boxes into a salvaged, slatted barn creates a beautiful respite from the wine country summer. The careful application of mirrors amplifies the rustic while avoiding the trivial game of material contrast. The correspondence with the landscape is wonderful. This is architecture for the soul and mind.”
