Materials & Finishes
This fictional palette demonstrates how material behavior, ageing, sourcing, maintenance, and specification evidence can be explained before a client locks selections.
Structural Expression
Materials that do work and look like it — raw, honest, and beautifully resolved.
#A09A93Interior walls, wine caves, entry sequences. Forms leave their grain in the surface.
#C4A882Perimeter walls, retaining elements. Each layer a geological record of the site.
#B8855AStructural members, rafters, beams. Left unfinished or oiled to read the growth rings.
#8B4513Exterior cladding accents, gates, bridge elements. Oxidizes to a stable amber-rust.
Stone & Masonry
Quarried, cut, and set by hand. KEYSTONE sources all stone from verified regional suppliers.
#4A4A4AFloors, fireplace surrounds, kitchen counters. Dense, fine-grained, nearly imperviable.
#D4C9B0Exterior paving, pool surrounds, bathroom tile. Softens with age.
#5C6670Roofing, exterior cladding, wet areas. Extraordinary dimensional stability.
#F5F0E8Powder rooms, primary baths, kitchen counters. Used precisely, not everywhere.
Wood & Millwork
Every wood species and finish specified for how it will age — not just how it looks at handover.
#C9A96EWide-plank flooring, cabinet faces, wall paneling. Wire-brush reveals the ray fleck.
#3D2B1FFeature millwork, built-ins, stair treads. Fuming deepens the chocolate tones permanently.
#8B5E3CExterior siding, pergolas, screen walls. Class A fire resistance without chemical treatment.
#9E7A50Feature walls, barn doors, ceiling planks. Each board carries its own provenance.
Metal & Glass
Precision-fabricated, welded, and finished in-house by our millwork partner.
#2A2925Window frames, doors, stair railings, kitchen hardware. Patina develops slowly over years.
#8B7355Plumbing fixtures, cabinet hardware, switch plates. Unlacquered so it can develop character.
#E8F0EFLarge pivot doors, fixed glazing, shower enclosures. No green cast — pure light transmission.
#C0C0C0Kitchen appliances, commercial hoods, laboratory-grade counters. Hardest-working surface in the house.
Every material has a written specification.
Before any material leaves the distributor for a KEYSTONE site, it has a written specification: manufacturer, grade, thickness, finish, installation method, acceptable tolerance, and inspection criteria. We don't order 'the usual' — we order exactly what the drawings call out, verified against what arrives.
