Project Overview

This custom 3-story residential project in Orange County required comprehensive structural engineering for a modern family home featuring open floor plans, large windows, and contemporary architectural elements. Our team provided complete wood framing structural design to ensure the home meets all California building codes while achieving the owner's vision.

The 3,200 square foot residence presented unique structural challenges including complex floor joist systems to accommodate open living spaces, load-bearing wall configurations, and seismic resistance engineering per California requirements. Our licensed Professional Engineers delivered complete structural plans including foundation design, wall framing schedules, floor and roof framing plans, and connection details.

All structural engineering work was completed in just 2 weeks with permit-ready drawings and calculations, allowing the project to move forward quickly without delays. The design incorporates modern construction techniques while ensuring long-term structural integrity and safety.
