IDEA Archteriors

IDEA Archteriors is a Southern California-based architecture and interior design studio founded by Lydia Alfred, AIA, a California-licensed architect with over 20 years of experience across two continents. Rooted in the belief that every designed place begins with an IDEA, the studio brings architecture, interiors, and thoughtfully crafted details together to create spaces that feel authentic, purposeful, and deeply connected to the people who inhabit them. Our work spans custom homes, renovations, additions, boutique hospitality, curated commercial spaces, and places of worship and community. From initial concept and space planning to architectural documentation, material selections, custom elements, and finishing details, IDEA offers a cohesive design approach shaped by creativity, technical expertise, and a commitment to thoughtful execution. Based in Southern California. Designing everywhere. A STORY OF PLACE.
