Every builder makes material choices. Most don't explain them.
The specification sheet exists — products, manufacturers, grades — but the reasoning behind it rarely gets written down. Why this window system and not that one. Why natural finish stucco. Why brass hardware. Why the envelope assembly is detailed the way it is.
A material palette is a set of commitments about durability, maintenance, and how a building ages.
Exposed Structure
Our post-and-beam system uses Douglas fir for primary members and structural steel at moment connections and long spans. Both are left exposed wherever the program allows.
When structure is exposed, it has to be right. Tolerances acceptable in conventional framing are not acceptable when the beam is the ceiling and the column is the wall.
Douglas fir over engineered lumber: more dimensionally stable over time, machines and finishes cleanly, ages honestly — silvers slightly with UV exposure where it meets daylight. Engineered lumber is more consistent at the mill and less interesting in the building.
Envelope
The building envelope is where most long-term performance lives. It's also where the gap between code minimum and real quality is widest.
Title 24 sets a floor that most builders treat as a ceiling.
Continuous exterior insulation is standard in our assemblies. It eliminates thermal bridging through the framing — the path of least resistance that undermines R-value in a conventionally framed wall.
Waterproofing is treated as a system, not a product. Every penetration is detailed in the construction documents and reviewed in the field. Water intrusion doesn't announce itself until the damage is done.
Exterior Cladding
Natural finish stucco is our default for most LA residential applications. Appropriate to the climate, appropriate to the architectural language of the region, and when properly specified, requires almost no maintenance for decades.
The natural finish matters. Painted stucco is a maintenance cycle: repainting, moisture trapped behind cracked paint, a color you're locked into. Natural finish develops a patina. The color is in the material, not on it.
Where the program calls for something else — coastal applications, compositions that read better in metal panel — we have specifications for fiber cement, pre-weathered zinc, and board-formed concrete. Each chosen for durability and how it behaves over time, not how it photographs on completion day.
Windows and Doors
The highest-consequence material decision in a custom home.
We specify Marvin Ultimate as baseline: thermally broken aluminum frames with wood interior cladding, tested air and water infiltration ratings that hold up in real conditions, hardware that operates cleanly after twenty years.
Specifying a cheaper aluminum system to reduce the budget line looks reasonable on a spreadsheet. Aluminum that isn't thermally broken conducts heat and cold directly through the frame, undermining the envelope performance you've paid for everywhere else.
Hardware
Door pulls, window cranks, cabinet hardware, plumbing fixtures — touched hundreds of times a year. The quality of that interaction accumulates.
Brass is our default for most interior applications. Solid brass develops a patina that is not a failure mode. It can be relacquered, repolished, or left to age.
We work with Colonial Bronze, Sun Valley Bronze, and E.R. Butler for signature applications. Silicon bronze or 316 stainless for coastal exterior hardware.
Chrome and brushed nickel are not in our standard specification. Both are plated finishes over base metal. The plating wears at high-contact points, and the base metal beneath is not where you want to end up.
Finishes
Interior finishes are where personal expression is most concentrated and where we have the most flexibility. We don't impose a palette.
What we hold firm on: materials that are forgiving of daily life, honest about what they are, and capable of aging into something better rather than something worse.
Formaldehyde-free cabinet substrate is standard. Low-VOC finishes throughout. The Red List framework informs our specification as we develop it. The direction is toward materials that are better for the people living in them.
The Principle
Every material in our specification performs its function well over a long time, in the specific conditions of Los Angeles residential construction, and gets better with age and use.
We build homes designed to get better with age. The materials are the first expression of that.
