Design-build is revolutionizing how Los Angeles homeowners approach remodeling and construction projects. Unlike traditional methods where architects and contractors work separately, design-build firms streamline everything under one roof—from initial concept and design through permitting, construction, and final walkthrough. This comprehensive guide explores LA's leading design-build firms for 2026, highlighting those that deliver exceptional results through integrated project delivery.
What is Design-Build and Why Does It Matter?
Design-build is a project delivery method where one entity—the design-build firm—holds a single contract to provide both design and construction services. Rather than hiring separate architects and contractors who may have competing interests, design-build creates a unified team accountable for the entire project from concept to completion.
This approach offers distinct advantages for homeowners in Los Angeles:
- Single Point of Contact: One team manages design, permits, budgets, and construction, eliminating finger-pointing and miscommunication
- Faster Project Delivery: Design and construction phases overlap, reducing timeline by 30-40% compared to traditional design-bid-build
- Cost Certainty: Early contractor involvement ensures realistic budgets with fewer change orders and surprises
- Enhanced Collaboration: Architects and builders work together from day one, preventing costly design-construction conflicts
- Streamlined Accountability: With one contract and one responsible party, disputes and warranty issues are resolved efficiently
For complex LA projects involving strict permitting requirements, historical home considerations, or challenging site conditions, the design-build approach significantly reduces risk and stress for homeowners.

New Dawn Construction exemplifies the design-build approach with seamless integration of design vision and construction expertise. The firm handles every aspect in-house—from initial concept drawings to final construction—ensuring homeowners work with one cohesive team throughout the process. This eliminates the common frustration of architects and contractors disagreeing about feasibility, budget, or timeline.
New Dawn specializes in kitchen remodeling services, bathroom renovation services, whole-home transformations, and room addition services.

The firm's deep expertise in LA permitting and building regulations makes them particularly valuable for projects in restrictive zones or historical districts.
Boswell Builders
Boswell Builders distinguishes itself through design-build expertise focused on sustainable construction. Their integrated team approach ensures eco-friendly design elements are buildable, cost-effective, and genuinely sustainable—not just greenwashing. From the earliest design concepts, Boswell's builders collaborate with designers to specify solar-ready infrastructure, high-efficiency HVAC systems, and sustainable materials that meet California's stringent energy codes.
The firm's design-build model prevents the common scenario where architects design ambitious sustainable features that contractors later deem too expensive or impractical. Boswell's unified accountability means green features are priced accurately from day one and executed without compromise. Clients appreciate that sustainability goals remain intact from concept through completion.
Patterson Custom Homes
Patterson Custom Homes leverages the design-build approach for luxury estate construction, where the complexity demands seamless coordination between design ambitions and construction realities.

Their design-build methodology includes Patterson Custom Care, a long-term maintenance program that reflects the firm's single-source accountability. Because Patterson oversees both design decisions and construction execution, they can provide comprehensive warranties and support that traditional separated firms cannot match. Clients value this continuity of service long after project completion.
Hanover Builders Inc.
With 35+ years of experience, Hanover Builders Inc. has perfected the design-build process for custom single-family homes. Their integrated team approach eliminates the costly change orders and timeline delays common when architects and contractors work independently.

Clients report high satisfaction with Hanover's transparent budgeting—because construction expertise informs design from the start, estimates are accurate and surprises are rare. The firm's flexibility comes from having design and construction under one roof; adjustments can be evaluated and priced in real-time rather than requiring formal change orders through separate contracts.
Design-Build vs. Traditional Design-Bid-Build: Key Differences
| Aspect | Design-Build | Traditional Design-Bid-Build |
|---|---|---|
| Contracts | Single contract with one firm | Separate contracts with architect and contractor |
| Timeline | Overlapping design and construction phases | Sequential: design complete before construction starts |
| Accountability | One entity responsible for entire project | Architect and contractor may blame each other |
| Cost Control | Builder input ensures realistic budgets upfront | Design may exceed budget, requiring redesign |
| Change Orders | Fewer changes; issues resolved internally | More changes due to design-construction conflicts |
| Communication | Single point of contact for homeowner | Homeowner coordinates between separate parties |

- Transparent Pricing: Ensure they provide detailed, itemized estimates that reflect the design-build integrated approach
