Structural Engineering for New Custom Homes

A new house has a lot of decisions. The structure is one you only get one shot at. We design the parts that hold the house up and keep it standing in an earthquake or a windstorm: wood-framed, one to three stories, on a crawlspace, slab or basement. Licensed Washington PEs.

Call Us
