Stairs

Open-riser feature stair

A stair built as architecture rather than circulation — thick hardwood treads, no risers, and a guard designed to the code limits that open risers trigger.

Capability, not a case study. This is work the shop is equipped and specified for. There is no photographed job of this exact type published yet — when there is, it appears here.

When this is the job

A renovation or new build where the stair is a designed object in a sightline. The aesthetic is simple; the code constraints are not, and they decide what is buildable before any drawing is worth having.

From $380–$850 per step, installed

HST extra. A range, not a quote — a firm number follows a moisture reading on site.

Worked example

$7,730$10,965

15 treads, white oak, Oakville · 5–8 days

Typical specification

  • Tread thickness engineered for span without a riser behind it
  • Open-riser opening limit respected — this is what most open-stair designs fail on
  • Structure designed with the stair, not concealed after it
  • Guard and handrail designed as part of the object, to code thresholds

Sequence of work

  1. 1Establish the code envelope first: rise, run, opening limits, guard height.
  2. 2Design the tread section for span, then the structure that carries it.
  3. 3Confirm the design against the envelope before any material is ordered.
  4. 4Fabricate, dry-fit, and adjust in the shop rather than on site.
  5. 5Install, then build the guard and rail to the same drawing.

What goes wrong

The part of a hardwood job that costs money is rarely the part in the quote. These are the failures that produce a second invoice.

Designing the look before checking the open-riser opening limit

A drawing everyone has approved and nobody can build. The redesign lands after the client is emotionally committed to it.

Avoided by: Establishing the code envelope before the first sketch is shown.

Tread thickness chosen visually rather than for span

Perceptible deflection underfoot on a stair sold as a feature. Irreparable without rebuilding.

Avoided by: Sizing the tread for the span, then adjusting the aesthetic within that.

Structure resolved after the stair is designed

Visible supports added late, which is precisely the look an open stair was bought to avoid.

Avoided by: Designing stair and structure together from the start.
