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.
Framing, bracing, foundation design, stamped drawings and calcs, and answers to plan review.
Window walls mean less room for shear walls. Tell us early what matters most so we can plan for it.
