When the Drawings Come Before the Drilling
Have you ever signed a contract for a project you couldn’t quite picture yet?
Or wondered whether the team building your home is the same team that designed it?
This post looks at 4 firms in Riverside County that all use the design-build label, breaks down how each one actually handles design, and shows where the differences hide.
By the end, you’ll know how to tell a true design-build firm from a remodeling contractor offering design as part of the sales process.
4 Design-Build Firms Serving Riverside County
These 4 design-build contractors serve Riverside County:
- DHI Builds uses an independent design partner, Kevin O’Connor Design, instead of running design in-house.
- Golden State Home Repair signs the construction agreement at Step 3, before design and material selection happen at Step 4.
- Mastercraft Home Improvement emphasizes quick project starts with design handled as a single phase rather than a multi-step process.
- Box Construction runs an in-house Design Studio in Murrieta and finishes design before the construction agreement is signed.
DHI Builds
DHI Builds is a Murrieta-based remodeling contractor licensed in California since 2013.
Owner Donovan has 20+ years in the trades and runs the company with a focus on transparent project tracking.
Footprint and Team
DHI’s office is in Murrieta, with service across Riverside County and into San Diego.
Project communication runs through Buildertrend, a software platform that gives clients a 24/7 portal for photo logs, messaging, and payment tracking.
You can see daily progress without back-and-forth phone calls.
How Design Is Handled
DHI Builds doesn’t run design as an in-house specialty; it’s handled through a partnership with an outside designer.
The company works with Kevin O’Connor Design, an independent designer certified by both NKBA and CCIDC, who works with multiple contractors.
Kevin O’Connor Design runs its own client intake and process, then delivers production plans to DHI’s build team.
Golden State Home Repair and Renovations
Golden State Home Repair and Renovations is a family-owned firm that’s worked in the Temecula Valley for 25+ years.
The showroom is on Madison Avenue in Murrieta, with an A+ Better Business Bureau accreditation.
Local Presence and Team
The design lead is Chad, who came from HGTV, where he worked as a project manager.
The project lead is Mike, who’s been overseeing builds for 25+ years.
Together, they handle most projects from the showroom, from kitchens to additions.
Their Published 8-Step Process
Golden State publishes their full 8-step process directly on their website.
The distinctive part is when the construction agreement gets signed: at Step 3, before design and material selection happen at Step 4.
The phrase “assists with design” signals design as a step in the construction workflow rather than a specialty service that drives the project.
The 8 steps:
- Free estimate appointment.
- Review the estimate.
- Construction agreement sent for electronic signature.
- Design and plan, including material selection, appointments, and permits.
- Project timeline and payment schedule.
- Renovation.
- Project completion.
- Enjoy.
Mastercraft Home Improvement
Mastercraft Home Improvement runs two showrooms (Murrieta and Carlsbad) and reports 3,500+ completed projects since 2012.
Footprint and Volume
The two showrooms cover both ends of the service area: Murrieta for East Riverside County and Carlsbad for North County San Diego.
Coverage extends across Temecula, Vista, Oceanside, Encinitas, and surrounding communities.
Stated Process and Pricing Approach
Mastercraft’s construction process has 4 steps, with design treated as a single phase between consultation and the build rather than a specialty discipline.
Sales messaging is mostly price-led: a low-cost guarantee, a promise to beat any competitor, and 20-40% off materials through supplier partnerships like Blackstone Granite & Marble.
The 4 steps:
- Free in-home consultation and estimate.
- Design and concept.
- Project management.
- Final walk-through.
The design phase isn’t broken into separate stages like discovery, rendering, or material selection.
Box Construction
Box Construction is a Murrieta-based design-build firm serving homeowners across the Temecula Valley.
Our team handles design and construction services under one roof, so the same people who draw your floor plan are the ones building your home.
The Murrieta Design Studio
A lot of design-build firms run design as a digital process: catalogs, screen renderings, and online samples.
We run a physical Design Studio in Murrieta where you can hold the tile, the cabinet door, and the countertop slab in real light.
That hands-on piece helps you avoid the “it looked different on screen” surprise that’s hard to undo once construction begins.
How the Design Phase Is Structured
The design phase is a structured 4-step design process, with each step building on the last, so the layout locks in before you pick a finish.
By the time you reach material selection, the floor plan is already final.
The 4 steps:
- Discovery & Analysis: Conversations about how you live and what’s driving the remodel.
- Mood Board: Visual direction and aesthetic style.
- 3D Rendering & Floor Plans: Detailed visualizations in SketchUp and using photorealistic renderings; cabinets done with 2020 Design.
- Logistics & Scheduling: Thorough handoff/project walkthrough between design and production at the home so everyone knows every detail, from designer to homeowner to PM. Gantt charts and the project timeline are handed to the build team.
How to personalize your home remodel.
When the Construction Agreement Gets Signed
The construction agreement gets signed after the design phase finishes, not before.
You’ve already seen the renderings, picked your materials, and approved the timeline before any contract goes out.
- Discovery and Vision
- Phone Consultation
- In-home visit with follow-up email, including a recap of work to be done and a budget bracketed
- Project Retainer $500+ for early coordination between designer, homeowners, project manager, and project coordinator.
- Design Retainer $3,000+
- Design and Planning
- Homeowner design meetings
- Floor plans & 3D renderings
- Material & finish selections
- Scope, timeline, and budget alignment
- Design presentation
- HIC contract signing
- Construction and Execution
- Pre-construction walkthrough
- Permits & scheduling coordination
- Construction begins
- Ongoing project management & communication
- Design and construction team collaboration throughout the build
- Completion and Reveal
- Final walkthrough with homeowner
- Final payment
- Professional cleaning
- Final details & project completion
- Aftercare details, warranty paperwork, and project coordinator after project communication expectations
That design-first sequence brings real cost savings: design upfront saves an average 6% in costs and finishes projects 33% faster.

Communication During the Build
Once construction begins, communication stays consistent across the entire project.
You hear from your project manager daily, designer weekly, and project coordinator throughout the duration of the project.
Our design-build team stays engaged through the construction phase, so the people who designed the layout answer questions if the crew hits something unexpected.
How to Tell a True Design-Build Firm From a Contractor Offering Design
All 4 of the firms above use the design-build label, but only 1 runs design as a specialty discipline.
The difference hides in 3 structural choices that shape what your project feels like from contract to completion.
When the Construction Agreement Is Signed
Contractors who offer design as a sales aid typically send the construction agreement once the estimate is accepted, then run design after the contract is signed.
True design-build firms wait until design is fully developed first, with renderings, floor plans, and material selections locked in.
The order changes whether design adjustments become formal change orders or stay part of the original scope.
Box Construction works the design-first way, finishing renderings, floor plans, material selection, and scheduling before the agreement is signed.
Whether Design Happens In-House or Through a Partner
The design-build label doesn’t always mean the designer and the build team work for the same company. It also doesn’t mean the designer stays engaged once construction begins.
True design-build firms keep design internal as a specialty service; remodeling contractors offering design typically partner with independent designers who run their own client process and hand off finished plans.
Worth asking the firm:
- Is the designer on staff at the construction firm?
- Does the designer attend site visits during the build?
- Is the designer part of the same team as the project manager and crew?
How Custom the Discovery Phase Actually Is
Contractors who treat design as a sales aid tend to have a short design phase with template layouts that fit most homeowners, but not specifically you.
True design-build firms run a longer phase that digs into space planning rooted in how you actually live.
Signs of a true design-build firm:
- Multiple documented steps in the design phase, not one big design block.
- Software like SketchUp or 2020 Design is used before the contract.
- A discovery conversation that asks how you live, not just what to remodel.
Whether you’re remodeling in Temecula, Murrieta, Menifee, or Fallbrook, the depth of design upfront often separates firms that finish near the original budget from those that hit unexpected costs after construction begins.
Why choose a design-build company for your project?
Design-Build vs Design-Bid-Build vs Contractor-Plus-Design
There are really 3 project delivery methods worth knowing, not 2.
Design-Bid-Build
In a traditional design-bid-build setup, you hire an architect first to create the plans.
Then you put those plans out to bid with multiple general contractors and pick the one who builds them.
That’s 3 relationships, 3 separate contracts, and 3 timelines stitched together.
Design-Build
Design-build collapses all of that into one team under a single contract, with the same firm handling design and construction as a specialty discipline.
Real cost data informs the design from day one, and there’s a single point of accountability if something goes sideways.
Contractor-Plus-Design
The third spot on the spectrum is contractor-plus-design, where a remodeling contractor offers design help as part of selling the build but doesn’t run design as a specialty.
The contractor may use an in-house design assistant or partner with an outside designer, but design exists to support the construction sale rather than drive the project.
That’s where most of the firms calling themselves design-build in Riverside County actually sit.
Most homeowners going with a true design-build firm in the area do it specifically to skip the back-and-forth of either managing 2 separate teams or working with a contractor whose design phase is built around closing the deal.
Box Construction: Trust From First Call Through Final Walkthrough
Every Box Construction client moves through the same 4-step process that ends in success. Whether your project is a kitchen, an ADU, an addition, or a whole-home remodel, that sequence stays identical, and the team that designed it is the same team that builds it.
