Design-build vs. hiring an architect first: which is faster and cheaper in LA?

"Should we hire an architect first, or go straight to a design-build firm?" is one of the first real decisions on a custom home, and it shapes everything after it: who you hire, when you find out what the house will cost, and who you call when the drawings and the site don't agree. Both routes produce excellent houses on the Westside every year. They just put risk in different places.

We're a design-build general contractor in Studio City, so we have a bias, and we'll say so up front. We also build from independent architects' drawings, and some of our favorite projects started that way. This article explains how each route works, where cost and time are gained or lost, and when the architect-first route is the better call.

How does each model work, step by step?

Architect first (often called design-bid-build):

1. You hire an architect under a written design contract.
2. The architect develops schematic design, then design development, then construction drawings, bringing in a structural engineer, a Title 24 energy consultant and others as needed.
3. The drawings go to LADBS for plan check, and the architect answers the corrections.
4. You send the finished drawings to several general contractors for bids, or negotiate with one.
5. You sign a construction contract with the builder. The architect usually stays on for construction administration: answering questions, reviewing submittals and visiting the site.

Design-build:

1. You hire one company for both design and construction, often as a design contract first and a construction contract once the design and price are settled.
2. Design and pricing move together. Each design stage is checked against the budget by the people who will build it.
3. The same team submits for plan check, answers corrections and prepares the construction price.
4. Construction starts with the designers and builders already on the same page, and questions from the site go to one place.

The difference that matters most is when the builder's knowledge enters the process. In architect-first, it arrives after the drawings are done. In design-build, it arrives on day one.

Do I need an architect to build a house in Los Angeles?

Not always. California's Business and Professions Code section 5537 allows people who aren't licensed architects to prepare plans for wood-frame single-family homes of up to two stories and a basement. The building official can still require a licensed architect or engineer for any part of the structure that departs from conventional framing, and in practice almost every custom home has a structural engineer's stamp on its structural drawings.

The California Architects Board puts it simply: in many cases an architect isn't required for a single-family home, and you should ask your local building department what your project needs. If you do hire an architect, the Board's consumer guide lists what a written architect contract must include, and you can verify any architect's license on the Board's website.

So the question isn't whether the law requires an architect. It's what kind of design team your house needs, and who should lead it.

Where is cost certainty gained or lost?

Design-build gains certainty early. Because the builder prices each design stage, you see the cost of a choice while it is still a line on a drawing. A 20-foot opening, a cantilevered roof or a basement shows up as a number before it becomes a commitment. If the total drifts above budget, the design is adjusted, not redrawn after bids come in.

Architect-first gains competition late. When several builders bid the same complete drawings, you get a true comparison of construction prices. The risk is timing: if every bid comes in over budget, the design has to be cut back after months of work and fees, then sent through plan check again. That redesign loop is the most common way an architect-first project loses both time and money.

Where both can lose it. The number in any proposal is only as good as what's inside it. Two things to watch, whichever route you choose:

• Scope and exclusions. Every proposal excludes something. Ours, for example, lists items such as solar, low-voltage and audio-visual wiring, landscaping, hardscape and custom closet systems as excluded unless they're added in writing. What matters is that exclusions are written down where you can see them.
• Finishes. Many of our clients choose and buy their own finishes (tile, plumbing fixtures, lighting, appliances, stone) with our help sourcing them, so the construction price covers the build and the installation. That keeps the finish budget in your hands, but you need a realistic number for it from the start. Our pricing guide shows how the total splits between building, finishes, and design and permits.

For a new home with mid-to-upper finishes, our planning range is roughly $400 to $700 per square foot of living space, including finishes and design and permit work, before land, government fees and site work. Our article on custom home cost per square foot explains what moves a house within that range.

Where do the months go?

On any custom home, time goes into four phases: design, plan check and permits, bidding or pricing, and construction. The two routes differ mainly in the first three.

• Design. Design-build can be shorter because cost checks happen as the design develops, instead of after it's finished. The time savings disappear if decisions are slow, whichever route you choose.
• Plan check. Both routes go through the same LADBS review and the same correction rounds. What helps is a complete, coordinated submittal; what hurts is drawings that change after submission.
• Bidding. Architect-first adds a distinct bid phase: builders need time to price complete drawings, and you need time to compare them and negotiate. In design-build, pricing has been running alongside the design, so it's largely done by the time the permit is ready.
• Construction. Similar either way. Questions from the field get answered faster when the designer and builder work together, and slower when they have to pass through separate contracts.

We deliberately haven't put month counts on these phases. They depend on the house, the lot and how quickly decisions get made, and a single number would be more misleading than useful.

When is hiring an independent architect the better call?

We'd recommend it, even though it isn't our model, when:

• You want a specific architect. If a particular designer's work is why you're building, hire them. The house should be theirs.
• The design is the point. Highly sculptural or unusual houses benefit from an architect whose only job is the design, with the freedom to explore before cost enters the conversation.
• You want competitive bids on complete drawings. Some owners value a side-by-side construction price above everything else, and complete drawings are the only way to get one.
• Your lender, HOA or a review board expects an architect of record. Some do, especially on complex or hillside sites.

A good middle path is to hire your architect and bring a builder in early, at schematic design, for budget pricing and constructability review. You keep your independent designer and gain early cost feedback, and we are glad to work that way.

How do we handle design and construction at 1 Degree?

We work both ways. On design-build projects, we sign a separate design contract before a construction contract. It covers as-built measurements of an existing house, drafting and engineering, Title 24 energy calculations, 3D renderings, plan-check submittal and up to two rounds of revisions, plus help choosing finish vendors. Design fees are paid in stages as the drawings progress, not up front.

When a client arrives with an architect's or designer's drawings, we price and build from those plans and work with the design team through construction.

Either way, the construction contract is the same: a fixed price, with payments tied to milestones such as foundation, framing, rough systems, drywall and finishes. The deposit is $1,000 or less. We provide unconditional lien releases with each payment. Any change, including structural work not shown on the approved plans, is priced and approved in writing before the work begins. The Contractors State License Board requires a fixed-price contract and the same down-payment cap ($1,000 or 10% of the price, whichever is less) on home improvement work, including fire rebuilds and ADUs. We follow those rules on every project. Our page on how we price a project explains how our proposals work.

What should I ask, whichever route I choose?

1. Check licenses. Look up any contractor on the CSLB license check and any architect on the California Architects Board's site.
2. When will I see a construction price? At schematic design, at design development, or only after bids?
3. Who prepares the structural drawings and energy calculations? And who answers LADBS corrections?
4. What does the design contract include, and how are revisions charged? Ask how many rounds are included.
5. What's excluded from the construction price? Get the list in writing.
6. Who buys the finishes, and what budget should I hold for them?
7. How are changes priced and approved? Insist on written change orders before work starts.
8. What's the payment schedule? Payments should follow completed work, with lien releases.

If you're not sure which route fits, our comparisons page sets out the trade-offs side by side, and our fit page is honest about when we're not the right builder. We're glad to look at a lot, a sketch or a set of drawings and tell you what we'd do.
