Why rift-sawn, and why white oak
A white oak log can be cut three ways. Plain-sawn boards show the familiar cathedral grain. Quarter-sawn boards show the dramatic medullary ray fleck. Rift-sawn boards, cut at roughly 30 to 60 degrees to the growth rings, show neither: just tight, straight, parallel lines. That restraint is why we use rift-sawn almost exclusively for face frames, door stiles and panel runs. The eye reads the whole wall as one quiet surface rather than a collection of boards.
Rift-sawn also moves least across its width with seasonal humidity, which matters in a Portland house that runs at 65% relative humidity in January and 35% in August. Less movement means our 3 mm reveal stays 3 mm.
White oak itself is chosen for its closed cell structure, which takes hardwax oil evenly, and for a tannin content that lets us ebonise or fume it when a darker tone is wanted without stain.
Western walnut as the accent
Where a desk top, a stair handrail or a kitchen island calls for warmth, we specify Western walnut, often from orchard trees pulled out of the Willamette Valley. It is softer and more figured than white oak, so we hold it to horizontal surfaces and hand-touched elements, and we edge-band it with solid stock at least 10 mm deep so the arris can be re-profiled after a decade of use.
The 3 mm shadow-gap reveal
Every door-to-door, door-to-panel and panel-to-plaster junction in our work carries a 3 mm reveal. It is a single number, held everywhere, and it is the thing most people notice without knowing why. The reveal is routed into a blackened steel or painted MDF sub-frame set behind the face so the shadow reads deep and dark. Where millwork meets lime plaster we stop the plaster on a 3 mm steel angle rather than letting it run into the oak, which lets both materials move independently.
Tolerance is ±0.5 mm. Our fabricators achieve this with CNC-cut carcasses and door blanks trimmed after the finish has cured, then hung on adjustable hardware and set in place on site with a steel feeler gauge.
Concealed hardware
We specify Blum throughout: CLIP top BLUMOTION 110° hinges with integrated soft close, LEGRABOX drawer boxes with a 40 kg dynamic rating for kitchens, and TIP-ON mechanical touch-latch for handleless fronts in studios and bedrooms where we want no pulls at all. Every hinge cup is bored at 35 mm diameter, 12.5 mm deep, 5 mm from the door edge. The shop drawings carry these dimensions so site carpenters can replace a hinge without calling us.
Inset doors are the default. Overlay fronts hide the carcass, but they cannot hold a shadow gap, and the gap is the point.
Zero-VOC hardwax oil
Lacquer makes oak look like a photograph of oak. Hardwax oil, a blend of plant oils and waxes that cures in the fibre rather than sitting on top of it, keeps the surface matte, warm and repairable. We specify a zero-VOC, two-coat system applied in the shop under controlled humidity. Final sheen is 5 to 8 gloss units measured at 60°. Worn areas are re-oiled locally with no sanding back to bare timber, which is why a twenty-year-old oiled kitchen can look better than a five-year-old lacquered one.
What we review on shop drawings
- Grain direction on every face, with sequence-matched veneer leaves numbered from the flitch.
- Reveal dimension at every junction, including the floor reveal where a toe-kick is omitted.
- Hinge boring pattern, drawer runner lengths and load ratings.
- Panel core: lightweight MDF for painted work, veneer-core plywood for oak carcasses, solid stock at every edge the hand touches.
- Moisture content certificate at delivery, 6 to 8%, and a two-week acclimatisation period on site before fixing.
- Acoustic interface: where slatted oak fronts an absorptive cavity, slat width, gap and the depth of mineral wool behind.
