Two common paths to get your project built – what’s the difference and which one fits your goals?
Choosing How to Structure Your Project Team
One of the first major decisions you’ll make is how to structure your project. Some owners choose to hire a designer first and then bid the plans out to contractors. Others work with one team that handles both design and construction. These two approaches, Design-Bid-Build and Design-Build, each come with their own pros, trade-offs, and ideal use cases. Understanding the difference will help you decide what makes the most sense for your goals, timeline, and budget.
What Is Design-Bid-Build?
This is the traditional approach. You hire an architect to create your design, then once plans are ready, you put the project out to bid and hire a contractor. Design and construction are handled by separate entities.
Typical process:
- Hire an architect
- Finalize permit-ready plans
- Collect bids from contractors
- Hire a GC to build the project
Pros:
- Design Expertise: You work directly with an architect from the start
- More Control: You make separate decisions on design and construction
- Competitive Bidding: Multiple contractors can price the job
- Detailed Plans: Plans are often more complete before construction starts
- Flexibility: You’re not locked into a single team early
Cons:
- Budget Disconnect: Architects may design outside your budget if not checked early
- Higher Total Cost: Separate contracts and longer planning phases can increase fees
- Longer Timelines: The sequential process adds time
- Over-Designed Plans: Excess detail may drive up construction costs unnecessarily
Constructability Issues: Contractors aren’t always involved early enough to spot red flags - Potential Disputes: Misunderstandings between architect, owner, and contractor can arise later
What Is Design-Build?
With this approach, one team manages both design and construction under a single contract. That team might be a contractor with in-house design, or a collaboration between a builder and architect.
Typical process:
- Hire a design-build firm
- Begin preliminary design and pricing
- Finalize plans internally and submit for permits
- Proceed with construction
Pros:
- Simplified Communication: One point of contact from start to finish
- Faster Timeline: Design and construction phases often overlap
- Budget Transparency: Cost is considered early and adjusted along the way
- Permit Management: Many teams handle this in-house
- Better Site Awareness: Builders evaluate site conditions during design
- Local Knowledge: Teams are often familiar with materials, suppliers, and inspectors
- More Client Involvement: Frequent check-ins and hands-on collaboration
- Lower Initial Cost: Fewer up-front design fees compared to hiring an architect separately
Cons:
- Less Competitive Bidding: You’re typically working with one firm from the beginning
- Limited Plan Detail: Plans may not be detailed enough for third-party pricing
- Reduced Design Control: Clients have less say in selecting design professionals
- Contractual Lock-In: Harder to switch designers or contractors once started
- Conflicts of Interest: The builder may influence design decisions to prioritize construction efficiency
Project Delivery Comparison: Design-Bid-Build vs. Design-Build
Category | Design-Bid-Build | Design-Build |
Team Structure | Architect and contractor are hired separately | One team handles both design and construction |
Contract Setup | Two contracts: Owner–Architect and Owner–Contractor | One contract: Owner–Design-Build Firm |
Timeline | Linear (design first, then bidding, then build) | Overlapping phases, faster start |
Design Control | Higher – Owner works directly with architect | Moderate – Design is integrated with construction |
Competitive Bidding | Yes – Bids from multiple contractors | No – Single team selected up front |
Cost Transparency | Variable – Contractor pricing comes later | High – Pricing discussed early and refined during design |
Construction Input | Limited during design (unless a contractor is consulted early) | Integrated from day one |
Owner Involvement | Higher – Owner manages separate relationships and decisions | Moderate – One point of contact simplifies coordination |
Risk of Disputes | Higher – Possible disconnect between design and construction teams | Lower – Same team manages both sides (but may require careful oversight) |
When It’s Ideal | Custom homes, complex or high-detail design projects, or when contractor flexibility is important | Remodels, additions, ADUs, or when speed and simplicity are top priorities |
Which Approach Is Right for You?
Choose Design-Bid-Build if:
- You want more control over design and team selection
- You’re building something custom, detailed, or complex
- You’re comfortable managing multiple parties
- Competitive pricing is a priority
Choose Design-Build if:
- You want a streamlined process with one point of contact
- You’re working with a strict budget or timeline
- You prefer early cost feedback and fewer unknowns
- You want less administrative coordination
There’s no one-size-fits-all answer. Some owners prefer to build a custom team of experts; others value the simplicity of one team managing the entire process.
What’s Next: Custom Home vs. Remodel vs. ADU
Now that you understand the different project delivery methods, it’s helpful to look at how that process shifts depending on the type of project you’re planning.
Whether you’re building a home from the ground up, renovating an existing space, or adding an accessory dwelling unit (ADU), the overall phases might be similar—but the requirements, timelines, and team involvement can vary significantly.
Head to Custom Home vs. Remodel vs. ADU to see how each path differs and what to expect depending on your project type.
