Why local matters
Land at a scale the inner Eastside does not have
Duvall is a small city on the Snoqualmie River northeast of Redmond, between the suburbs and the Cascade foothills.
The valley around it has farmland, horse properties and rural lots of 2 to 20 acres and more. On those sites the house, barn, shop and guest quarters can be planned as one compound.
Inside city limits, the City of Duvall permits. The valley parcels go through King County.
What gets designed here

Questions
Building in Duvall, answered
Do you work in Duvall?
Yes. Piper Cole Architects is based in Kirkland and Duvall is part of the regular work. Rural estates, accessory buildings and hillside homes are the core of it.
How long does a permit take in Duvall?
Inside the city, allow 6 to 10 weeks for an addition and 10 to 16 weeks for a new house. Rural King County parcels typically take 12 to 20 weeks.
What does an architect cost in Duvall?
Typically 8% to 15% of construction for full service, toward the top of that range on waterfront, steep or otherwise constrained lots because they take more design time. The architect fees page has a calculator for your own budget.
Do I need an architect for a house in Washington?
Not by law. RCW 18.08.410 exempts single family homes and buildings of four units or fewer from the stamp requirement. You will need permitted drawings and usually structural engineering. People hire an architect because the lot, the code or the design is complicated, not because the law requires one.
What happens on the first call?
You describe the property and what you want to do. David Meade tells you what the site and the code are likely to allow, what it tends to cost and what to check first. The first feasibility check is free and usually takes about a day.
