Interiors that
evolve with
the home.

From a refreshed living room to a full second story — every interior update and structural addition handled by the same team, so nothing feels like an afterthought.

We update interiors and add square footage across Los Angeles and Ventura Counties — living rooms, primary suites, and full footprint expansions — matched so closely to the existing home that nothing reads as new. Every project is fully permitted, inspected, and scoped in writing before it begins — under California license #1094201.

How the Project Runs

The same sequence,
every time.

  • 01

    Consultation & Site Visit

    We walk the space with you, take measurements, and talk through how you use it today and what you need it to do. This visit is free and carries no obligation.

  • 02

    Design & Scope

    We develop the plan and a written scope of work, and settle materials before anything is signed. You see exactly what is and isn’t included.

  • 03

    Permits & Pre-Construction

    We submit drawings, pull the permits required by your city or county, and order long-lead items around their lead times.

  • 04

    Demolition & Rough-In

    Protection goes down, demolition happens, and structural, plumbing, and electrical changes are completed and inspected.

  • 05

    Installation & Finishes

    Cabinetry, stone, tile, flooring, fixtures, and finishes follow in sequence, each trade handed off cleanly to the next.

  • 06

    Walkthrough & Close-Out

    We walk the finished space with you, build and complete a punch list, and hand over warranty documentation.

Common Questions

Questions,
answered honestly.

Your contract is built on a defined scope, not a rough estimate — every material, fixture, and labor line is priced before we break ground. If something outside that scope turns up once work starts, you get a written change order with the exact cost before anything proceeds, never a surprise on the final invoice.

We build your schedule around the real LA permitting and inspection calendar, not a best-case guess, so the date you sign off on already accounts for plan-check and inspection wait times. If something outside our control pushes it, you hear about it the same week — not the week the deadline passes.

You get a single point of contact for the entire job, not a rotating cast of subs to chase down. We check in with you daily — by phone and by message — so you're never finding out about a problem after it's already cost you time.

Every job closes with a walkthrough and a written punch list — nothing is “done” until every item on it is fixed and you've signed off. We stand behind our work with the guarantee spelled out in your contract, and every trade that requires a license gets a licensed sub, not unlicensed labor to save a day.

We pull permits for anything LA requires a permit for, full stop, even when a smaller scope makes it tempting to skip. That protects you two ways: the city inspects the work as a second set of eyes beyond ours, and you're never the one holding an unpermitted addition when it's time to sell.

For most whole-home projects, yes — we sequence the work so at least part of the house stays livable, and we section off active work areas to contain dust and keep you out of the way of trades. The exceptions are scopes that touch your only kitchen or bathroom for an extended stretch, or work that disconnects utilities to the whole house — in those cases we'll tell you upfront during the design phase, not after demo starts, so you can plan around it.
