The Vault & Stack House completely reimagines a 1970s San Jose ranch home, expanding it by 680 square feet into a bright, open 2,880-square-foot contemporary home. By introducing strategic geometric layers and high-contrast finishes, the design shifts a dark, traditional layout into a contemporary classic.

The addition of staggered rooms along the west side form a dynamic, deep facade while funneling daylight into a new home office and two new bedrooms.In the front, two intersecting barrel vaults form a covered front porch, introducing a deep volume with soft geometric curves to the exterior profile.

Beside the entry, a sculptural, non-functional faux chimney creates striking visual relief on the facade, nodding to the classic front-facing chimneys of the local neighborhood while a new, low gabled roof cleanly merges two separate existing roofs over the main house and garage into one cohesive structure. The drought-tolerant grounds use high-contrast white dolomite rock, black mulch, and charcoal-topped pavers framed by low-profile plants.

Inside,  skylights placed over the new main entry hall ensure natural light penetrates deep into the core of the home as an interplay of glossy and matte white materiality creates subtle nuance among a neutral palette.
