Interior Design in Los Angeles — Full-Service ID, Custom Millwork, 3D Renderings, Built Under One License

LA interior design is a specific craft. It is not Houston ID, not New York ID, not Miami ID. The light is different. The architectural vocabulary is different — Spanish Colonial Revival from the 1920s, Mid-Century post-and-beam from the 1950s, Case Study Modernism, hillside contemporary, Cape Cod transplants in Brentwood, Mediterranean in Hancock Park, glass-walled minimalism in the Bird Streets. The clients are different — entertainment-industry, tech, finance, second-home international, multi-generational families. The neighborhoods have personality (Beverly Hills wants warm traditional, Silver Lake wants quirky-but-grown-up, Pasadena wants restrained, Manhattan Beach wants coastal-not-cliche). We are NPLD — architectural design since 2016, CSLB general contractor since 2023 (#1105249), 200+ LA completions. Our interior design practice is fully in-house. That means the ID who picks your slabs is sitting across the room from the architect who drew your floor plan and the project lead who is about to install it. Material selection, lighting design, custom millwork, hardware, paint, plaster, tile, stone, wallpaper, window treatments, art-placement consultation, furniture procurement at trade — all of it under one roof, one contract, one phone number, and one accountable license.

What full-service LA interior design actually costs in 2026

Real numbers from real LA projects in the last 14 months. Kitchen plus primary bath ID ($12K-$28K design fee): material selection, cabinetry spec, lighting plan, tile and stone, paint, hardware, plumbing fixtures, two rounds of revision, full 3D renderings — 4 to 8 weeks of design time. Full-home ID ($28K-$75K design fee): every room scoped, full material and finish schedule, lighting design with reflected ceiling plans, custom millwork drawings, furniture floor plans, paint and plaster schedule, hardware schedule, window treatments, art-placement consultation — 8 to 16 weeks. Luxury full-home ID ($75K-$200K design fee): all of the above plus imported stone selection trips, custom-furniture commissioning, antique sourcing, art curation consultation, Crestron or Savant prewire spec coordination, security and AV layout coordination — 12 to 28 weeks. Estate-tier ID ($200K-$450K design fee): 8,000-15,000+ sqft estate, full custom-fab millwork, imported European stone, hand-blown lighting, custom wallpaper or hand-painted murals, NDA at intake, LiveScan-cleared install crews, art-handler coordination, dedicated project lead for ID alone — 6 to 14 months. Procurement is separate from the design fee — furniture, hardware, lighting, stone, art are billed at our trade price plus a transparent procurement fee (typically 10-15%, fully disclosed, no hidden markup). Furnishings spend usually lands at $200-$600 per square foot for standard full-home, $450-$800 per sqft for luxury, $800-$1,500+ per sqft for ultra-luxury estate work.

LA design vocabularies — knowing the period before you design for it

The single biggest tell of a non-LA designer parachuting into Los Angeles is treating every house like a blank box. They are not blank boxes. They are: 1920s-1930s Spanish Colonial Revival (Hancock Park, Los Feliz, Whitley Heights) with hand-troweled stucco, clay-tile roofs, wrought iron, dark-stained wood, arched openings, Saltillo tile, deep-set windows — design language wants warm earth tones, hand-glazed tile, terra cotta, woven leather, antique European pieces. 1950s-1960s Mid-Century post-and-beam (Brentwood, Bel-Air, Mt. Washington, Silver Lake, Pasadena) with exposed beams, clerestory windows, glass walls to the garden, low-slope rooflines, terrazzo or polished concrete floors — design language wants walnut, teak, leather, brass, low-profile furniture, Eames-era pieces, a restrained palette. 1980s-1990s contemporary (Bel-Air, Brentwood, Pacific Palisades) with high ceilings, large windows, open plans — design language is more flexible but the architecture wants restraint. 2010s glass-and-steel modernism (Bird Streets, the Summit, Trousdale teardowns) with floor-to-ceiling glass, infinity edges, white-on-white — design language wants museum-grade material decisions and a very disciplined palette. 1920s Mediterranean (Hancock Park, Windsor Square, San Marino, Pasadena) — different from Spanish Colonial, formal symmetry, hand-painted ceilings, marble, formal European references. We design for the building. We do not impose a designer's signature on a building that does not want it.

Material selection — how the slab-yard trip actually works

Every full-home and luxury client gets a stone-yard day with us. Walker Zanger, Ann Sacks, Concrete Collaborative, Heath Ceramics, Exquisite Surfaces, Compas Architectural Stone, Mosaic House. We schedule one full day, we drive (not you), we have already pre-pulled samples that match your palette, and you walk the actual 10x6 slabs in natural light. Calacatta Vagli vs. Calacatta Gold vs. Statuario — the difference is real in person and invisible on a 4x4 sample. We approve the specific slab tags, we mark them for hold, the fabricator picks up that exact slab. No bait-and-switch. Same process for tile, hardwood, paint, wallpaper, leather. We have an in-house material library at the studio with 4,000+ samples for the first round of selection so the field trips happen with a tight short list, not a fishing expedition. Custom millwork: we draw it in Revit, we render it to your space, you approve the drawing, our in-house fabrication shop (in Sun Valley) builds it, our installers set it. One company from drawing to install — no GC handing it to a millwork sub who hands it to a finisher who hands it back to the GC, with each handoff burning a week and a paint match.

Lighting design — the most undervalued line item in LA interior design

Light is the single most powerful design tool in a Southern California interior, and it is the line item homeowners under-spend on more than any other. We do full reflected ceiling plans on every project. Layers: ambient (recessed cans, often DMX-dimmable), task (under-cabinet, vanity, reading), accent (art-wash, niche, cove), and decorative (pendants, sconces, chandeliers, table lamps as composition pieces). Color temperature is engineered per room and per time of day on smart-control systems — 2700K warm in the bedroom at 7pm, 3500K in the kitchen at 7am, scenes for entertainment vs. cooking vs. dining vs. sleep. Driver and fixture compatibility is checked before order — half the lighting headaches in LA homes are because someone bought $80,000 of fixtures and $200 of drivers that flicker or cannot dim past 30%. We spec the driver to the fixture, we spec the controls to both, we coordinate with the AV integrator on Crestron or Savant or Lutron. Decorative lighting is procured through our trade accounts at Apparatus, Allied Maker, Lindsey Adelman Studio, Vibia, Roll and Hill, Visual Comfort — you see the trade price, you see our procurement fee, no markup games.

Custom millwork, cabinetry, and built-ins — drawn, built, installed in-house

Cabinetry and built-ins are where most LA interior design projects bleed time and money. The conventional path is: ID specs a vendor like Bulthaup or SieMatic for $180K, lead time is 18-26 weeks, the GC subs the install to a third-party finish carpenter who has never seen the spec before, the cabinets arrive with a damaged corner, the install date slips three times. We do almost all our cabinetry in our own shop in Sun Valley. Drawing in Revit to the millimeter. CNC cut. Hand-finished. Door style and species per the design. We can hit Bulthaup-level fit and finish at about 55-65% of the price, with lead times of 8-12 weeks instead of 18-26, and with our own installers who built the cabinets setting them. The exception: clients who specifically want a name-brand European kitchen, in which case we will spec and install Bulthaup, SieMatic, Boffi, Poliform, or Molteni and we have factory-trained installers on staff for each of those brands. Same model applies to built-ins — bookshelves, banquettes, mudroom storage, primary closets, wine rooms, libraries.

3D renderings, VR walkthroughs, and the design-decision process

Every interior design project at every tier gets photorealistic 3D renderings in V-Ray or Enscape, not flat elevations. We render the actual furniture you are buying, the actual paint color on the wall, the actual stone on the counter, the actual wood floor with the actual stain, lit at 9am, 4pm, and dusk. You see the room before any procurement happens. Two rounds of revisions are included; additional rounds at a transparent per-revision fee. On luxury and estate projects we add a VR walkthrough on Meta Quest 3 — you stand in the room at scale, walk to the window, sit in the chair, see the art at the height the installer will hang it. This is not an upsell. This is how we design, because the median LA interior design project bleeds about 18-22% of its budget on changes-after-installation, and the single biggest cause is the homeowner saying 'I did not realize the rug clashed with the floor' on day 90. If you walked the model on day 30, you caught it on day 30.

Procurement, trade, and the markup conversation

Honest conversation about money. Furniture, lighting, hardware, stone, tile, art, and accessories are not in the design fee — they are procured separately. We have trade accounts with about 400 LA-relevant vendors: Holly Hunt, A. Rudin, Lawson-Fenning, Lucca Antiques, Croft House, Big Daddy's, Garde, JF Chen, Brentwood antique row, Avalon Antiques, the LA Mart, Pacific Design Center showrooms, Apparatus, Allied Maker, Visual Comfort, Hudson Valley, RH Modern. Trade discount runs 20-50% off retail depending on the vendor. We charge a procurement fee, fully disclosed in the contract, typically 10-15% of the trade-discounted cost (estate-tier projects sometimes 18%). The math: you usually still pay materially less than retail even after our fee, and we handle the procurement, expediting, white-glove delivery coordination, damage claims, and install. The contract spells out exactly what the trade price is and exactly what our fee is on every line. No designer-markup-on-top-of-trade-discount games. No 'design retail' or 'list-plus-25' that is the dirty open secret of high-end LA interior design.

Why design-build ID under one CSLB license is materially different

Two hundred-plus LA builds taught us that the gap between a beautiful ID spec and a beautifully installed room is usually about 14% — and that 14% lives in the seam between the designer and the contractor. The drawing says 'tile installed in a perfect 1/16-inch grout joint'; the tile-setter installs it at 3/16 because that is what he always does. The drawing specs 'paint laid down in three coats with a 320-grit sanding between coats'; the painter does two coats and skips the sanding. The drawing specs a particular fixture; the GC's plumber subs in 'an equivalent' because it was on his truck. None of this happens at NPLD because the designer and the installer work for the same company under the same CSLB license. Quality control is a single conversation, not three meetings and a change order. Our QC checklist for ID install is 240+ line items, signed off room by room before the homeowner sees the work. The result is install quality that matches the rendering — which, frankly, is the entire point of hiring an interior designer in the first place.

Frequently Asked Questions

Do you do design-only, or do I have to use NPLD for construction too?

Design-only is fine. About 25% of our ID clients use a separate GC for the construction side and bring us in for material selection, lighting, custom millwork, and procurement. We will work directly with your GC, attend job-site meetings, and supervise install. Design-build is more efficient and we recommend it where possible, but it is not required.

How does your procurement markup work, and how is it different from other LA designers?

We charge a transparent procurement fee — typically 10-15% of the trade-discounted price, disclosed line by line in the contract. Many LA designers charge 'design retail' (retail price minus a designer discount, with the markup hidden in the difference between their trade price and what they bill you) which obscures the actual fee. We show you the trade price, we show you our fee, you sign one number. No hidden markup.

How long does a full-home interior design project take in LA?

Design time: 8-16 weeks for standard full-home, 12-28 weeks for luxury, 6-14 months for estate. Procurement lead times after design approval: 10-26 weeks depending on what is custom and what is in stock. Construction install (if design-build): runs concurrently with procurement for shell work, sequenced after for finish. Total project from kickoff to move-in: 6-9 months for standard full-home, 9-14 months for luxury, 14-24 months for estate.

Do you do custom millwork in-house or sub it out?

In-house. We own a 12,000 sqft millwork shop in Sun Valley. We can custom-fabricate cabinetry, built-ins, paneling, custom doors, custom stairs, and architectural millwork at Bulthaup-level fit and finish for 55-65% of the European-import price. If you specifically want Bulthaup, SieMatic, Boffi, Poliform, or Molteni, we are factory-trained on each and we install them ourselves.

Can you work with my existing furniture and art, or do I have to start over?

We always work with what you already love. The first design meeting includes a walk-through of every piece you want to keep — furniture, art, rugs, lighting, heirlooms. We photograph and measure each, build them into the 3D model, design around them. Most full-home projects keep 30-60% of existing pieces. We never push a 'tear it all out' plan unless you ask for one.

Are your design crews and install crews discreet and confidential for celebrity clients?

Yes. Estate-tier and luxury-tier projects include an NDA at intake covering NPLD employees and any sub on site. Our estate-tier install crews are LiveScan-cleared. We coordinate with the homeowner's existing security team, work around personal schedules, use unmarked vehicles when requested, and never photograph the site without explicit written permission. About 18% of our estate-tier clients are entertainment-industry; the discretion protocols are battle-tested.

Do you do imported stone selection trips to Italy or Spain?

Yes, for estate-tier projects. We coordinate with stone yards in Carrara, Verona, and Alicante. The trip is typically 4-6 days, you select specific slabs at the quarry or at the fabricator, slabs are tagged, exported, and shipped to LA. We handle freight, customs, and import. Trip cost is at-cost (flights, hotels, in-country transport); the slabs are at our import trade price plus the disclosed procurement fee. About 12% of our luxury and estate clients do this.

Do you coordinate with smart-home, AV, and security integrators?

Yes. We work routinely with the major LA AV and smart-home integrators — Theatron, AVA, Eagle Sentry, Smart Home Integration, Pinnacle, Wipliance. Coordination includes prewire spec at the architectural drawing stage, fixture and touchpanel placement at the ID stage, color and material match on touchpanels, in-wall speaker layout, and rack-room design. The integrator is contracted separately by the homeowner, but we manage the design coordination at no extra fee.

What is included in the lighting design — is it actually engineered, or just fixture selection?

Full reflected ceiling plan for every room. Layered lighting (ambient, task, accent, decorative). Color temperature engineered per room and per scene. Dimming and control spec coordinated with the AV integrator (Lutron, Crestron, Savant). Driver-and-fixture compatibility verified before order. Photometric calculations on critical spaces. Mock-ups installed for art-wash and accent lighting before final placement. This is engineering work, not just shopping.

Do you do estimates and design presentations in Spanish?

Sí. Our ID team is bilingual. Design presentations, material boards, contracts, and on-site communication can run in English, Spanish, or both. About 18% of our LA ID clients sign in Spanish.

What if I just want a consultation — not a full project — to point me in the right direction?

We offer a paid 2-hour design consultation at $850 (credited back if you sign a project within 90 days). We come to your home, walk every room, take photos and measurements, give you a written direction document covering palette, key material decisions, lighting recommendations, and rough budget. About 30% of consultations turn into projects with us; the other 70% take the direction document to a different designer or do it themselves. No pressure.

What is the warranty on interior design work and installation?

Design work: 1 year of free revisions if any specification turns out to be unavailable or backordered past the project timeline. Installation workmanship (design-build clients): 2 years on everything we install, parts and labor. Custom millwork: 5 years on structure, 2 years on finish. Manufacturer warranties on furniture, lighting, hardware, fixtures, and appliances pass through to you at closeout.
