Good questions, answered plainly.

Cerro Studio serves fourteen luxury residential markets across California and the Mountain West — Central Coast (Montecito, Hope Ranch, Santa Ynez, Ojai, Carpinteria), LA Westside, Orange County, San Diego County, SF Peninsula, Palo Alto, Napa, Sonoma, Desert (Indian Wells / La Quinta), Monterey Peninsula, North Lake Tahoe, Scottsdale / Paradise Valley, Aspen, and Jackson Hole. The Montecito flagship serves the Central Coast directly; LA and SF satellites serve the rest, with travel-delivered Mountain West projects.

Warm handcrafted editorial — lime plaster, reclaimed French oak, honed travertine and limestone, unlacquered brass, raw linen, hand-finished tile, integrated art programs. Our work moves between Spanish Colonial Revival, Mediterranean, and modernist-Mediterranean hybrids depending on parcel and client. Every project is site-specific.

Lena Hartwell founded Cerro Studio in 2014. She is the principal designer on every Full-Service engagement and leads schematic design through final installation personally. The studio is seven people including a project manager, procurement coordinator, and design team scaled to active workload.

Coast Village Road, Montecito, CA 93108 — by appointment. The studio houses the materials library and current-project work. The Los Angeles satellite is open in Culver City; the San Francisco satellite opens 2027 in Dogpatch.

Full-Service Design fees start at $180,000 for a whole-home engagement; Single-Room Residency starts at $38,000 fixed-fee for one room; Studio Consult is $4,800 flat for a half-day on site (fully credited toward a future engagement); Plan Review is free. Construction and FF&E are separate and scoped per project.

Total turnkey luxury new construction ranges from approximately $700/sqft (Desert, Sonoma) to $5,000/sqft (Aspen) in 2025–26. The Central Coast runs $1,200–$2,500/sqft elevated luxury; LA Westside runs $1,500–$3,500/sqft; Palo Alto and SF Peninsula run $1,200–$3,000/sqft. The Cost Estimator at /cost-estimator returns a defensible budget band for any specific project.

Fully. Every vendor invoice is shared with the client. The mark-up policy is written into the engagement contract. There are no hidden margins and no vendor kickbacks. Procurement is run through a dedicated coordinator with weekly logs delivered to the client throughout the project.

Interior design and FF&E (furniture, fixtures, equipment) typically represent about 22% of total turnkey project cost. On a $5M Central Coast project that line item runs approximately $1.1M, including Cerro's design fee plus custom furniture, lighting, art coordination, fabric program, hardware, and procurement.

Full-Service runs 14–24 months across six phases: Discovery (4–6 weeks), Concept (6–10 weeks), Design Development (12–18 weeks), Procurement (10–20 weeks, overlapping construction), Installation (2–4 weeks), and Living In (12 months post-occupancy).

Single-Room Residency is 10–14 weeks for one fully-designed room with the same principal designer, the same procurement standards, and the same custom-millwork capability — just compressed in scope. Many clients use Single-Room as a way to assess fit before booking Full-Service.

Within five business days — often sooner. Every inquiry is read by the principal designer and the studio manager. Plan Reviews receive a written assessment within five business days. Cost-estimator submissions receive the detailed line-item breakdown immediately on submit, plus a follow-up note from the studio.

The principal designer who took your inquiry leads your project end-to-end. Cerro Studio does not hand engagements off to juniors. The principal is supported by a project manager and procurement coordinator with additional designers scaled to project complexity, but the principal is in every material review, every site visit, and every install week.

Yes — Cerro Studio collaborates with the architect and builder from schematic design forward. The studio works alongside roughly 60 architecture firms and 60 builders across the 14 markets, including Marc Appleton, Wallace E. Cunningham, Walker Warner, Howard Backen, Aidlin Darling, Marmol Radziner, Feldman Architecture, and Butler Armsden. We can also make introductions if you don't yet have a firm.

An architect designs the building envelope and structure (foundation, framing, exterior, jurisdictional review). An interior designer designs the architecture inside the envelope (wall plans, lighting circuits, finishes, custom millwork, FF&E). Both are required on serious luxury residential projects. See /vs/architect-vs-interior-designer for the full comparison.

Cerro serves as design director for the indoor-outdoor experience and coordinates with landscape architects on every Full-Service project. Cerro partners with firms like Arcadia Studio, Hoffman & Ospina, and Montecito Landscape rather than delivering landscape architecture in-house.

Yes. Begin with a Studio Consult ($4,800, half-day on site) or a free Plan Review if you have early architectural drawings. The principal designer will return a written assessment within five business days, including architect and builder recommendations specific to your market.

Yes — restoration is roughly 25% of delivered projects, with a five-firm specialty network for heritage trades (handmade Mexican tile, hand-forged wrought iron, plaster artisans, tile-roofing specialists). Restoration projects on documented architect-designed homes (George Washington Smith, Wallace Neff, Lutah Maria Riggs) are a particular focus.

Lime plaster is a matte, breathable hand-troweled finish; Venetian plaster is a polished marble-rich multi-coat finish. Lime is ~$15–$35/sqft installed; Venetian is ~$35–$120/sqft. Most Cerro homes use lime plaster as the dominant wall finish with Venetian reserved for two or three feature rooms. See /vs/lime-plaster-vs-venetian-plaster.

Yes — boutique hotels, restaurants, tasting rooms, spas, private clubs, and retail across the Central Coast. The studio's hospitality practice mirrors the residential discipline at commercial scale, with operator fluency, durability specifications, and FF&E procurement managed in-house. See /hospitality.
