Do you need an architect, a designer, or a builder?

The three roles, honestly described

Architect

A licensed architect designs the building and produces the drawing set that gets permitted. On anything that moves structure, adds floor area, or goes up from nothing, this is the person who starts the project. They work alongside a structural engineer, who sizes the beams and the foundation and stamps that work.

You need one when the shape of the building changes. Additions, second storeys, removing bearing walls, ground-up construction, and most detached ADUs.

Designer

An interior designer chooses how the space looks and feels. Layout within existing walls, cabinetry, finishes, tile, lighting, colour, hardware. On a kitchen or a bath where the walls are staying put, a good designer is often the difference between a room that works and a room that merely got replaced.

You need one when you want the result designed rather than assembled, and when you do not already know what you want.

Builder

A licensed general contractor prices the work, pulls the permits, carries the subcontractors, runs the schedule and is responsible for what gets built. That is us. We hold a California General B licence, number 1112902.

We build your vision. We are not designing the place with you. That is a deliberate position, not a gap we are apologising for. Alfredo came up through the trades and runs this as a builder, and a builder pretending to be a designer produces exactly the mediocre outcome you would expect.

So which do you need first?

Run your project through this once and the answer is usually obvious.

You already have a permitted drawing set

Then you need a builder, and only a builder. Send the drawings out, get them priced, and compare like for like. This is the cleanest possible start to a project and it is the one we are built for. We price it and we build it.

Your project changes the structure and you have no drawings

You need design before you can get a real price. Anyone giving you a firm number for an addition with no drawings is guessing, and the guess will be revised. Get the drawings, then get them priced.

If you do not have an architect, say so early. We coordinate the architect and the structural engineer routinely and carry that work inside the project, so you are not left to assemble a team from scratch. On an ADU a full set including Title 24 runs about $10,000, and the design team submits to the city portal.

Your project keeps the existing walls and you know what you want

You probably need neither an architect nor a designer. A kitchen that stays in its footprint, a bathroom taken back to the studs and rebuilt properly, a whole-house refresh with no structural change. Bring the finishes you like and we will build it.

On projects like these we hand over a materials list and a rendering once the price is agreed, so you can see the room before it exists. That is the whole design offering, deliberately. What we will not do is sit and pick vanity colours with you, because a designer will do that better and you deserve the better version.

Your project keeps the walls and you do not know what you want

Hire a designer. Not us, and not a builder who says yes to designing it. This is the case where people most often get talked into letting the contractor design by default, and it is where the regret comes from.

The expensive mistake, and it is always the same one

Paying for a design that cannot be built at your budget.

It happens like this. Someone commissions a full drawing set with no builder involved and no realistic number attached. The set comes back beautiful. The first contractor prices it at nearly double what the owner had in mind. Now there is a choice between abandoning drawings that were paid for, or paying again to have them redrawn to a budget that should have been established at the start.

The fix is not complicated. Establish the realistic number before the drawings are finished, not after. A builder can tell you whether a concept is inside your budget long before the set is complete, and that conversation is cheap. We publish our ranges precisely so this can happen early: additions and whole-home work run $130K–$490K, and a good-quality ADU $300K–$360K for a good-quality build.

One route that skips a lot of this

If you are building an ADU, California law now requires every city to run a pre-approved plan programme and publish the approved plans. Where a suitable plan exists, the design has already been reviewed, and what remains is fitting it to your specific site.

That can remove a large part of the $10,000 plan cost and shorten the approval path considerably. It does not remove the site work, the utilities or the geotechnical questions, which are what actually move an ADU number. But it is worth asking your city about before you commission anything custom.

What to ask on the first call

Whoever you end up hiring, these four questions sort the project out quickly:

• Does this project move structure, or stay inside the existing walls?
• Do I already have drawings, and are they permitted or just concepts?
• What is the realistic range for this scope before I commission anything?
• Who is responsible for the permit submittal and the plan-check corrections?

That last one catches people out. Drawings alone are not a permit. Someone has to carry the submittal and answer the corrections, and it should be clear from the outset whether that is the design team or the builder. On our projects it is us.

Where we fit

We are the builder. If you have plans, we will price them and build them. If you need design, we will tell you that plainly and point you to someone who does it properly, and we will still coordinate the architect and engineer inside the project so it does not become your job to manage.

We work across Santa Clara and San Mateo counties, deliberately in a tight radius, so travel time does not come out of your project. If you want to test whether your project is realistic before you spend anything on drawings, book a Project Discovery Call and we will tell you what is achievable at your number, including when the answer is that we are not the right builder for it.
