What 'Design-Build' Means in Outdoor Contracting
Design-build is one company under one contract for design, engineering, permits, construction, and warranty. The alternative — design-bid-build — splits design (architect/designer), bidding (3+ contractors), and build (the winner) into separate companies. Design-build wins on 4 of 5 dimensions: cost, speed, accountability, change-order rate, and warranty.
Why Design-Build Beats Design-Bid-Build
- Single contract, single warranty, single point of responsibility
- Design priced by the team that will build it (no surprises)
- Construction can begin in phases as design completes
- 5–15% lower total cost (no double markups)
- Faster timeline (design + permit + build run in parallel)
- Change orders run 5–10% vs. 15–30% on bid-build projects
When NOT to Use Design-Build
- If you're using a celebrity architect for the design only
- If you're committed to selecting the lowest bid regardless of design quality
- If your project is purely repair/replacement with no design component

💡 Pro Tip
Ask any design-build contractor: 'What does your average project run in change orders as a percentage?' If they don't know, they're not tracking — and they're not in control.
Frequently Asked Questions
What is a design-build contractor?
One company that handles design, engineering, permits, construction, and warranty under a single contract. The alternative is hiring a designer and a contractor separately.
Is design-build cheaper than design-bid-build?
Usually 5–15% cheaper because there's no double markup, less duplication, and fewer change orders from coordination errors.
Does design-build limit my design options?
Only if the contractor lacks in-house design talent. Strong design-build firms have architects, designers, and renderers in-house.
Can I bring my own designer to a design-build contractor?
Yes — many design-build firms will execute a designer's plans and warranty the build. Pricing the design they didn't author is sometimes higher.
Who's responsible if something goes wrong?
The single design-build contractor. That's the entire point. With separate designer and builder, blame ping-pongs and you pay to resolve it.
What size projects suit design-build?
Anything with multiple trades — pool + hardscape, kitchen + pergola, full backyard. Single-trade work (just turf, just a fence) is fine with a specialist.
