Walnut House

Costa Mesa, CA

Currently Under Construction

2-Story, 4 bedroom, Office, Bonus Room​, 3 Car Garage

3,200 Square Feet

Many homeowners today are reluctant to take on the repair burdens and risks associated with houses that are over 50 years old. As a result, we’ve entered the era of spot lot replacement—where aging homes are replaced with new construction on individual lots. This trend reflects a growing desire among buyers to enjoy the benefits of a newly built home while remaining in the charm and character of classic American neighborhoods. By adhering to the city's design guidelines and maintaining familiar, practical layouts, this new home will blend seamlessly into its surroundings—offering modern materials and upgrades while preserving the warm, cozy feeling of a traditional home.
