Why Me?
Seamless Integration
I work directly with your architectural team as an embedded structural designer — providing continuous support from concept to permit approval. No hand-off delays, no back-and-forth hassle.
PE-Stamped Designs
All ADU structural calculation reports and drawings are prepared to PE standards and issued through my U.S.-licensed PE collaborators. Stamps are valid for permit submission in your project’s state.
