This renovation and expansion of a ranch-style home in Cupertino, California, adds approximately 800 square feet of new living space on a second floor to accommodate the needs of a growing family.

The project reorganizes the existing house around a new entry foyer and more open dining and living areas, improving circulation and creating a stronger sense of connection between the primary family spaces. The second-floor addition provides substantial new living area while allowing the home to expand largely within its existing footprint.

A central design challenge was introducing a second story to a traditionally horizontal ranch house without overwhelming the original structure. The addition is composed to maintain the residential scale and character of the existing home while giving the renovated house a cohesive contemporary identity.

Together, the new upper level and reconfigured ground floor allow the house to accommodate changing family needs while making more efficient use of its existing site and footprint.
