Design-Build vs. Hiring an Architect Separately: What's Right for Your Seattle Remodel?

What's the difference between design-build and design-bid-build?

In the traditional design-bid-build model, you hire an architect first. They design the project, produce permit drawings, and then you take those drawings to several general contractors for bids. Designer and builder work for you separately, under separate contracts. In design-build, one firm (or a GC with a design partner) owns both halves: design happens with construction pricing in the room, and the team that priced the project is the team that builds it.

Where design-bid-build shines

Separate architecture makes sense when design itself is the point: a one-of-a-kind custom home, a complicated hillside or view lot, historic-district work, or a project where you want independent design advocacy and competitive bids on a finished drawing set. Bidding a complete drawing set also gives you real apples-to-apples price comparison — if you go this route, our guide on how to read a remodeling bid shows how to normalize those bids before you choose.

Where design-build wins for most remodels

For the typical Seattle-area kitchen, bathroom, basement, addition, or whole-home remodel, design-build usually gets you to a finished project faster and with fewer surprises, for three reasons. Cost reality enters early: the design is priced as it's drawn, so you don't fall in love with a $400k drawing on a $250k budget and lose months redesigning. One accountable party: when something in the drawings doesn't match what's inside the wall — common in this region's older ramblers and split-levels — there's no architect-vs-contractor finger-pointing; the same team solves it. Shorter timeline: permitting, selections, and pre-construction overlap instead of running in sequence.

Is design-build cheaper?

Not automatically — and be wary of anyone who promises it is. You typically save on redesign cycles, on change orders caused by drawings that didn't anticipate field conditions, and on the weeks or months a separate bid phase adds. You give up the downward price pressure of competitive bidding. The honest framing: design-build tends to produce a more predictable number, especially on a fixed-price contract, while design-bid-build can produce a lower headline number that is more exposed to change orders. Allowances and exclusions decide which bid is actually cheaper — same as in any contract.

Questions to ask either way

Who stamps and submits the permit drawings, and in whose name are permits pulled (see our Washington permit guide)? Is the construction price fixed, and what can change it? How are design changes priced once construction starts? Is the builder registered and bonded with WA L&I — verify with the state's free lookup, as covered in our guide to choosing a contractor. And for design-build specifically: can you see projects where the built result matched the drawings and the budget?

The bottom line for Seattle-area homeowners

If your project is primarily about buildable square footage and finishes — remodels, additions, ADUs — a design-build process with a fixed-price contract usually gets you the most predictable result. If your project is primarily an architecture problem, hire the architect first and bid it well. Blue Lake Construction runs design-build remodels across Bellevue, Seattle, and the Eastside, and we also build from owners' architect drawings — happily, on the same fixed-price terms.
