SV Design Architecture + Interiors

About

SV Design is a full-service architecture and interior design firm grounded in the belief that thoughtful design strengthens communities and enriches everyday life. For nearly four decades, our work has been defined by a deep understanding of how people experience space—how they live, learn, gather, and connect.

Our integrated team collaborates closely across disciplines, bringing architecture, interiors, planning, and sustainability into a seamless design process from concept through completion. We serve a wide range of markets including residential, multi-family and affordable housing, education, community and nonprofit, commercial, and hospitality.

Guided by a human-centered approach and a respect for context, we create enduring spaces that are functional, expressive, and deeply responsive to the people and places they serve.
