[02] Services

Five practices, under one roof.

Architecture and interiors in one practice, by design. The room and the building are the same conversation.

01

Architecture

Ground-up residential, civic, and small commercial work. Stamped drawings under our own license. Construction administration to certificate of occupancy.

02

Interior design

Specified end-to-end: cabinetry, hardware, lighting, FF&E. We work with a short list of fabricators we trust and we don't take referral fees.

03

Adaptive reuse

Cast-iron, masonry, light industrial. We take Landmarks meetings seriously. Two of our adaptive-reuse projects have shipped under historic tax credit.

04

Master planning

Campus, multi-building, and phased work. We hold the long view across owners, contractors, and the inevitable scope change in year three.

05

Workplace interiors

A growing practice. Studios, offices, public-facing spaces for technology and creative companies. We design for the long run — built-ins over freestanding, day-lit over overhead, real materials over MDF wraps.

[03] Process

Five phases. Sometimes seven years.

We follow the AIA phases by the book — because they work. We embed deeply in each: site visits in every season, mock-ups before approval, weekly site walks in CA.

01 · site visit

Site visit

We see the site in at least two seasons before we draw. We meet the neighbors. We bring back rocks and photographs and a long memo.

02 · SD

Schematic design

Three massing studies, one favored, presented in physical models at 1/8". We don't render. The drawing has to do the work.

03 · DD

Design development

Plans, sections, elevations to a level any contractor can bid. Material selection in real samples on the actual site, never on Pinterest.

04 · CDs

Construction documents

Stamped drawings, full spec book, schedules. We coordinate structural, MEP, civil, and landscape. We do not value-engineer the building's spine.

05 · CA

Construction administration

Weekly site walks until completion. RFIs answered in 48 hours. We're at the punch list. We're at the certificate of occupancy.

Halcyon Lodge sits on a ridge two hundred feet above the Pacific, on a parcel that had been logged in the 1920s and grown back into a coastal forest. Our client — a software founder with a deep dislike of glass houses on cliffs — asked for something that could sit through a winter storm without rattling.

The plan is simple: three volumes, each oriented to a different view, connected by a continuous spine that runs north-to-south down the contour of the ridge. The structure is exposed Douglas-fir glulam, the cladding is shou sugi ban cedar (charred in the field, by us, over four days in June). A single chimney — basalt, drystacked from a quarry seven miles east — anchors the living volume.

Eighteen months from broken ground to certificate of occupancy. The general contractor was new to the firm; he stayed on for two more projects after. We logged 64 site visits across the build, never fewer than two of us on site.

The lodge was awarded an ALA Honor in 2024. The owner's family spent Thanksgiving 2024 there. The chimney works.

A note on cost: this was not an inexpensive house. We are happy to share the line items with serious clients on the same kind of program. We try not to repeat the same building twice.

"We told them we didn't want a building that announced itself. Two years on, half of our friends drive past the property without seeing it. The other half cry when they walk in."
