Design build services put design and construction under one contract. One team draws your plans, prices them, pulls permits and builds the project. You approve drawings and a budget before work starts, instead of hiring an architect first and then bidding the plans out to contractors. That single point of responsibility usually means fewer surprises and faster decisions.
What does design build actually mean?
Design build means one company is responsible for both the drawings and the construction. You sign with a single team. That team designs the space, prices it, handles the permit paperwork and then performs the work.
The older approach is called design-bid-build. You hire a designer or architect, pay for a full set of plans, then send those plans to three contractors for bids. If the bids come back over budget, you pay to redesign. Design build closes that gap because the people building the project are pricing it while it is still being drawn.
For an Orinda homeowner, that matters. Many homes here sit on sloped lots with drainage, retaining walls and tight access. Those conditions affect cost. A team that designs and builds sees them early, not after plans are finished.
How do design build services work from first call to final walkthrough?
The process usually moves through five stages. The names vary by company, but the sequence is consistent.
1. Consultation and site visit
Someone comes to the house, looks at the space, and listens to what you want. They check the obvious constraints: ceiling heights, where plumbing runs, whether a wall is load bearing, how equipment will reach the work area. You talk about a realistic budget range in this meeting, not later.
2. Design and planning
Drawings start. Early versions are rough, showing layout options. You react, the plan changes, and the drawings get more detailed. Structural engineering comes in if you are moving walls, adding a second story or building on a slope. Selections begin too: cabinets, tile, flooring, fixtures, paint.
3. Pricing and scope agreement
The design team prices the drawings as they develop. That is the core advantage. You see what each decision costs while you can still change it. TRD Pros prices both a remodel inside the existing footprint and an addition during design, so homeowners can compare the two paths side by side before committing.
4. Permits
Plans go to the city for review. The building department checks structure, energy compliance, egress and setbacks. Corrections often come back. The design build team answers them because they drew the plans.
5. Construction and inspections
Demolition, rough framing, mechanical and electrical rough-in, inspection, insulation, drywall, finishes, final inspection. TRD Pros gives the homeowner a written schedule before demolition starts, so you know the order of work and the key dates.
Why do homeowners choose design build over hiring separately?
The main reason is accountability. With one contract, there is no argument over whether a problem came from the drawings or the framing. One company owns both.
- Budget reality earlier. Pricing happens alongside design, so you rarely finish plans you cannot afford to build.
- Fewer handoffs. The person who designed your kitchen island is reachable while it is being installed.
- Faster overall timeline. Permitting and some construction prep can overlap with late-stage design decisions.
- Buildable details. Designers who also build tend to avoid details that look good on paper and fail on site.
Design-bid-build still makes sense for some projects, especially highly custom architecture where the design vision comes first and cost follows. For most kitchen remodels, bathroom remodels, whole-house updates and additions, design build is the more practical route.
How do permits work for a remodel in Orinda?
Permits for work inside Orinda city limits go through the City of Orinda’s building and planning divisions. Structural changes, new electrical circuits, plumbing relocations, additions and most exterior alterations require review. Inspections happen at set points during construction, and each one must pass before the next stage of work is covered up.
Orinda adds a few local layers worth knowing about. Much of the city is hilly, so grading, drainage and retaining walls can trigger extra review. Tree protection rules apply to many mature trees on residential lots. Properties in high fire hazard areas face additional requirements for exterior materials, vents and defensible space. Some parts of town are on septic rather than sewer, which affects what you can add in bedrooms and bathrooms.
None of this is a reason to avoid a project. It is a reason to have plans drawn by people who deal with local review regularly. TRD Pros handles the permit application and coordinates inspections for its projects, which keeps the paperwork and the field schedule aligned.
What does a design build project cost?
Cost depends on scope, not on square footage alone. The factors that move the number most:
- Layout changes. Keeping plumbing and walls where they are is far cheaper than moving them.
- Structural work. Removing a bearing wall means beams, posts and engineering. Hillside additions may need new foundation or pier work.
- Footprint. An addition adds foundation, framing, roofing and siding that a remodel inside existing walls does not.
- Finish level. Stock cabinets and porcelain tile price very differently from custom millwork and stone slabs.
- Systems. Older homes often need electrical panel upgrades, new plumbing lines or HVAC changes to meet current code.
- Permits and engineering. Fees, drawings and reports are real line items.
- Access and site conditions. Narrow driveways, steep lots and limited staging space add labor time.
To get a number you can rely on, you need a site visit and a defined scope. A quote given over the phone without either is a guess. Ask for pricing that lists allowances for finishes, so you can see which choices are locked and which still have flexibility.
What should you ask before signing a design build contract?
Ask what the design fee covers and what you own at the end of it. Ask who draws the structural plans. Ask who submits the permit and who meets the inspectors. Ask how change orders are priced and approved in writing.
Then ask about schedule. A written schedule before demolition is a good sign. It shows the team has thought through material lead times, inspection windows and the order of trades. Cabinets and windows in particular can take weeks to arrive, and a schedule built around real lead times is much more honest than one built around hope.
Finally, ask to see completed work similar to yours. A team that has built additions on sloped Contra Costa lots understands what that involves.

Design & Build Services questions in Orinda
Is design build cheaper than hiring an architect and contractor separately?
Not always cheaper, but usually more predictable. Because pricing happens during design, you avoid paying for a full plan set that comes back over budget and needs redesign. You also skip the bidding period. Total cost still depends on scope, finishes and structural work. The savings show up most in avoided rework and a shorter overall timeline.
How long does the design phase take before construction starts?
Design commonly takes several weeks to a few months, depending on complexity. A single bathroom moves quickly. An addition with structural engineering, hillside drainage and city review takes longer. Your own decision speed matters too, since selections like cabinets, tile and windows must be locked before ordering. Permit review time is separate and set by the city.
Do I need a permit to remodel a kitchen or bathroom in Orinda?
Usually yes. Moving plumbing, adding electrical circuits, altering walls or changing windows all require a permit through the City of Orinda. Cosmetic work like painting or replacing cabinets in the same layout often does not. Because rules vary by project, confirm with the city or have your contractor check before work begins.
Can a design build team work with plans I already have?
Yes, most will review existing plans and price them. Expect some revisions. Drawings made without construction input sometimes include details that are expensive or impractical to build on your specific lot. A design build team can value-engineer those areas, update the set for permit submittal and then handle construction under one contract.
