Residential Engineering
We specialize in structural designs for single-family homes, townhomes, and multi-family residential developments. Our engineers collaborate with architects to create builder-friendly solutions that maintain architectural intent while ensuring structural integrity. From custom homes to large-scale subdivisions, we address site-specific challenges and local building codes across the Pacific Northwest.
Mixed-Use Structures
Our firm excels at designing buildings combining residential and commercial spaces under one roof. We handle complex load requirements for developments featuring apartments over retail spaces, live/work units, and mixed-use complexes. Our structural solutions optimize functionality while meeting zoning regulations and safety standards for urban developments.
