Design-Build Remodel vs. Separate Contractor + Architect
| Factor | Design-Build (Custom Home) | Separate Contractor + Architect |
|---|---|---|
| Single Point of Contact | One team from design through construction | You coordinate between architect, designer, and builder |
| Cost Transparency | Line-item pricing for every material before construction | Architect fees plus contractor estimate with allowances |
| Design Changes | All changes resolved in design phase at no cost | Architect revision fees plus contractor change orders |
| Timeline | Design and build schedules integrated from day one | Design delays push back construction start |
| Accountability | One contract, one team, one point of responsibility | Finger-pointing between architect and contractor is common |
| Cost Control | The price you approve is the price you pay | Change orders add cost and delay timelines |

Frequently Asked Questions
How much does a whole-house remodel cost in the Bay Area?
Whole-house remodel costs in the Bay Area vary widely based on scope, materials, and structural work involved. A cosmetic refresh runs significantly less than a gut renovation with layout changes. Our design phase gives you a complete itemized scope so you know exact costs before any demolition begins.
How long does a whole-house remodel take?
Most whole-house remodels take 4 to 12 months depending on scope. A cosmetic update may take 4 to 6 months, while a gut renovation with structural changes can take 8 to 12 months. The design phase typically adds 2 to 3 months upfront, but saves time during construction by eliminating mid-project decisions.
Do I need to move out during a whole-house remodel?
It depends on the scope. For cosmetic updates, we can often phase the work so you stay in part of the home. For gut renovations involving plumbing, electrical, or structural changes, we typically recommend temporary relocation for comfort and safety.
What permits are needed for a home remodel?
Most remodels involving structural, electrical, or plumbing changes require permits. We handle the entire permitting process with your local jurisdiction, whether that's San Jose, Palo Alto, Los Gatos, or elsewhere in the Bay Area.
How do you phase a remodel so I can stay in my home?
For projects where you want to remain in the home, we create a phasing plan during the design stage. This typically means completing work in sections, finishing one area before starting the next. We coordinate plumbing and electrical shutoffs to minimize downtime and maintain at least one functional bathroom and kitchen area throughout the process.
How do you coordinate multiple trades on a whole-house remodel?
Whole-house remodels require tight coordination between electricians, plumbers, carpenters, tile installers, painters, and other specialists. Our project managers create detailed schedules that sequence trades efficiently, reducing idle time and preventing conflicts. Every subcontractor we use is licensed, insured, and directly supervised by our team.
How do you keep me informed during a whole-house remodel?
You receive weekly progress updates with photos and milestone reports. A dedicated project manager serves as your single point of contact throughout the entire project. For whole-house remodels that span multiple months, we also provide monthly summary reports that track progress against the original timeline and budget.
