#resilient
At Roble Hill Studio, we build for resiliency
in homes
in buildings
in communities
in relationships
As expert designers and structural engineers, we bring the exact same rigor to everyday residential expansions and custom homes as we do to complex seismic evaluations, forensic investigations, and institutional peer reviews.

Your Design-Build Partner
Roble Hill Studio is a premier permitting, design, and construction company dedicated to serving Altadena homeowners with exceptional architectural and engineering solutions tailored to their unique needs.
We are engineers and contractors by trade who fell in love with our community after purchasing our first home on the border of Altadena and Pasadena. With a unique skill set—both of us being licensed structural engineers and one of us having years of experience with a general contractor—we bring a deep understanding of design and construction. After countless questions from family and friends and becoming actively involved in the community, especially in the wake of the fires, we realized the need for fair, accessible, and expert building services. Our goal is simple: to share our knowledge, serve our neighbors, and bring integrity and quality to a market that needs it most.
If you have questions, visit our dedicated website for the community, created specifically to address Eaton Fire-related concerns we've been hearing from clients and community members.
