Discovery & feasibility
We sit down with your goals, your site, and your budget — then pressure-test what's actually buildable here: zoning, setbacks, utilities, and the real cost range before anyone draws a line.

“I am so happy I used Avorino to build my two custom homes in Santa Ana. The team was absolutely amazing and made the whole process seamless and streamlined. The quality of work was absolutely fantastic and top notch all the way. Avorino treated my project as if it was their own and I knew I was in good hands — 10/10 experience.”
Why design-build wins
Design and construction, drawn at the same table.
In the traditional model you hire an architect, get drawings, then bid them to contractors — and find out months in whether the design was ever buildable on budget. Design-build collapses that gap: the people who'll build it help shape it from day one.
One contract, one company — design and construction under the same roof, accountable for both.
We price the design as it's drawn, so the budget is real before you ever approve a set of plans.
Overlapping phases — permitting and long-lead orders begin while the design is still being refined.
A single point of responsibility from concept to final inspection. No finger-pointing, no playing project manager.
From a first conversation to your keys.
Every phase is handled in-house, so nothing gets lost in translation between the people who designed it and the people who build it.
Design-build vs. design-bid-build
The same project, two very different experiences.
“Design-bid-build” is the traditional, sequential path: design it, bid it, then build it — with you in the middle. Here's how the two stack up on the things that actually decide how a project goes.
Design-Build (Avorino)Design-Bid-Build (traditional)
ContractsOne contract, one roof for design + build.Separate contracts with an architect and a contractor.
AccountabilitySingle point of responsibility — we own the result.Split — if something's wrong, the parties point at each other.
BudgetPriced as it's designed; locked before we break ground.Unknown until the bids come back — often over.
TimelinePhases overlap — studies show up to ~30% faster delivery.Strictly sequential: design, then bid, then build.
Change ordersFewer — industry data shows ~6% fewer change orders.More, from gaps between what's drawn and what's buildable.
Your roleOne point of contact. You make decisions, not phone calls.You're the middleman between architect and builder.

Design-build, answered
What people ask before they start.
What is design-build?
Design-build is a project-delivery method where one company handles both the design (architecture and engineering) and the construction under a single contract. Instead of hiring an architect and a contractor separately and managing the handoff yourself, you work with one point of accountability from the first concept through the final walkthrough.
What's the difference between design-build and design-bid-build?
Design-bid-build is the traditional, sequential path — you design a project fully, put it out to bid, then build it. Design-build overlaps those phases under one roof and one contract. The payoff is a budget that's known before you break ground, faster timelines, fewer change orders, and a single point of responsibility instead of an architect and a builder pointing at each other.
Is design-build cheaper than hiring an architect and a contractor separately?
It's usually more predictable, which is what saves money. Because a builder prices the design as it's drawn, you avoid the classic surprise where bids come back over budget after months of design. Industry research (DBIA) shows design-build projects average roughly 3.8% less cost growth and about 6% fewer change orders than design-bid-build.
Is design-build faster?
Yes — typically meaningfully faster, because design and construction overlap instead of running back-to-back. Permitting and long-lead material orders can begin while the design is being finalized. Studies have measured design-build delivering on a substantially faster schedule than the traditional design-bid-build path.
Is Avorino a licensed design-build company?
Yes. Avorino is a fully licensed Orange County design-build company (California State License Board #1107538) carrying architecture, structural engineering, Title 24, permitting, and construction in-house — a single point of accountability from first sketch to final inspection.
What kinds of projects can you design-build?
Custom homes, ADUs, additions and second stories, whole-home and kitchen/bath renovations, and commercial tenant improvements — across all of Orange County. The same one-team model carries each from concept to keys.

What is design-build, and why does it matter in Orange County?
Design-build puts architecture, engineering, permitting, and construction under one contract and one accountable team— instead of hiring an architect and a general contractor separately and refereeing between them. Budget shapes the design from day one, the bid can’t blow up after approval, and one Avorino team carries the project from feasibility to keys. License #1107538.
| Phase | What happens |
|---|---|
| Discovery & feasibility | We sit down with your goals, your site, and your budget — then pressure-test what's actually buildable here: zoning, setbacks, utilities, and the real cost range before anyone draws a line. |
| Design & engineering | Architecture, structural engineering, and Title 24 are developed together, in-house. You see your home take shape while a builder keeps every choice grounded in what it costs and how it's built. |
| Pre-construction & budget | We value-engineer the set, lock allowances, and hand you a fixed, line-item budget and schedule. This is where design-build earns its keep — no surprise bids, no scramble after approval. |
| Permitting & plan-check | We submit, answer plan-check corrections, and shepherd approvals city by city across Orange County — while long-lead materials are already on order, so the calendar never stalls waiting on a stamp. |
| Construction | We build what we designed. Dedicated project management, a clean site, weekly updates, and finish-level craftsmanship — with the original budget as the reference, not a memory. |
| Finish & handover | Final inspections, a punch-list walked down to zero, and a careful handover with your warranty and care guide. You get the keys to a home that matches the renderings you approved. |
