Three paths, one process
Homeowners, commercial owners and developers ask completely different questions, so they should not share a page. Each path below leads to dedicated service pages that answer the exact search that brought someone here.
Residential & ADUHomes, ADUs, additions and remodels
Smaller residential projects run on the same process as our largest commercial work, just scaled. Published cost ranges, a paid feasibility review first, and permitting handled for you.
Commercial & DevelopmentTenant improvements, hospitality, retail, ground-up
Owners, tenants and national brands. Lease and site feasibility before signature, then design, permitting and construction with weekly cost and schedule reporting.
DevelopmentFeasibility, entitlements, multifamily, owner's rep
For investors, developers and owners underwriting a site: tested yield, a mapped approval route and construction cost you can put in a pro forma before the land closes. Current development work includes Palmdale multifamily, the Tarzana townhomes and the Yorba Linda expansion.
Find yourself in one line
Four kinds of client, four different first steps. Pick the one that describes you and the site takes you straight to the relevant work and the right entry offer.
Developers & investors
You are underwriting a site and need defensible yield, cost and approval timing.
Development feasibility studyCommercial property owners
You own or manage buildings and need value protected while they stay operating.
Commercial feasibility reviewBusiness owners & tenants
You are signing or fitting out a space and the build number decides the deal.
Pre-lease feasibility reviewHomeowners
You are adding an ADU, an addition or a remodel and want the real number first.
Residential or ADU feasibility reviewOne team from feasibility to handover
Most projects lose money in the handoffs: the designer who never priced the drawings, the contractor who inherited drawings nobody could build, the owner left to referee. Plantek West holds all six steps, so cost, code and buildability are decided together.
- Step 1
Feasibility
Can it be built, what will it cost, what approvals does it need, how long will it take.
- Step 2
Design
Drawings developed against a live cost model, not priced afterwards.
- Step 3
Permitting
Submittals, corrections and agency clearances run by us.
- Step 4
Preconstruction
Constructability, procurement, phasing and schedule before mobilisation.
- Step 5
Construction
One line-item budget and one accountable team in the field.
- Step 6
Project management
Cost, schedule, change and closeout control through handover.
Track record
National brand work, and what it actually involved
A logo wall proves nothing. These are the programme types behind the names, because the transferable skill is multi-jurisdiction permitting and building inside operating properties without shutting them down.
Restaurant & QSR
Taco Bell / KFC / Pizza Hut / 7-Eleven
Multi-site restaurant and convenience programmes: prototype adaptation to each site, health department and fire sequencing, and permitting across separate jurisdictions on one schedule.
Retail & mixed use
Westfield / GNC / Luxottica / Williams-Sonoma
Retail build-outs and centre work inside operating properties: landlord work letter coordination, phased construction around trading hours, and centre-management approvals.
Hospitality
Hilton / Hilton Garden Inn / Edition
Hospitality renovation and fit-out work in occupied properties, phased floor by floor so rooms and public areas stayed in service.
Corporate, finance & tech
Citibank / AT&T / Uber / Pluto TV / Amgen / CBRE
Corporate and office tenant improvements: change of occupancy, accessibility upgrades, MEP coordination and weekly cost and schedule reporting to the tenant and landlord.
Start here
Start with feasibility, not a quote
Almost every expensive mistake in this industry comes from committing money before anyone answered four questions: can this be built, roughly what will it cost, what approvals does it need, and how long will it take. A paid feasibility review answers all four in writing, for residential and commercial projects alike.
- Can this use be permitted at this address?
- Does the occupancy classification work?
- Will accessibility or code upgrades trigger?
- What should be verified before signing a lease?
- What does the lot actually support?
- What hidden permitting risk exists?

Big photographs, accessible projects
Estate and commercial work photographs well, so it dominates portfolios. It does not represent the size of project we take. A large share of our work is single ADUs, garage conversions, additions and remodels, with published cost ranges so you can tell whether you fit before you pick up the phone.

Why this team can answer your questions
Plantek West is a design and construction company that takes projects from feasibility and entitlements through design, permitting and construction. Sandra Burga leads every project directly, which is why a single ADU receives the same process as a multi-site commercial rollout. Clients have included national retail, restaurant, telecom, financial and hospitality brands alongside homeowners across Los Angeles and Orange counties.
Credentials and experience
Named authorship, published experience and a steady review workflow are what move a firm from findable to chosen, in classic search and in AI answers alike.
Checklists that qualify, not just collect emails
Each guide is attached to an expensive decision someone is already trying to make. Trade an email address for the PDF, and every download joins the contact list with its topic attached, so follow-up can be relevant rather than generic.
Questions we answer before the first call
Where does Plantek West work?
Southern California, with offices in Santa Monica and Fullerton. We regularly work across Los Angeles, Orange, Ventura, Riverside and San Bernardino counties, and we have delivered multi-site programs beyond the region for national brands.
What is a feasibility study and do I need one?
A feasibility study is a short, paid assessment that answers whether a project can be built, at what approximate cost, under what approvals, and in what timeframe. It is the cheapest way to avoid spending design fees on a project the code, the site or the budget will not support.
How do you charge?
Feasibility work is a fixed fee. Design and construction management are typically fee-based on project value or scope, and construction is contracted with a defined line-item budget. You will always see how the number is built before you sign.
Are you helping homeowners rebuilding after the Eaton and Palisades fires?
Yes. We support rebuild efforts with design and plan submittal help so owners can move through approvals faster. Rebuild projects are prioritized in our intake.
What happens after I submit the contact form?
Your enquiry reaches us immediately by email and is logged with your project type, budget range and timeline, so the first conversation starts with your specifics rather than a blank page. You will hear back within one business day.
