Custom Wooden Staircases

Straight, quarter-turn or helical staircases in solid hardwood — engineered to your floor plan and finished to your style.

A staircase is the spine of your home. We design and build them in solid oak, walnut, ash or pine — straight runs, quarter-turn, half-turn or full helical. Every tread is mortised, glued and bolted to the stringer; treads come oiled, lacquered or painted, with optional anti-slip inserts and integrated LED lighting under the treads.

Designed to your floor plan

We start from your existing or planned floor plan, optimise the going and rise for comfort (typically 18 cm rise / 28 cm tread), and produce 3D drawings so you can see exactly how the staircase will sit in the room before we cut a single piece of timber.

Built to last generations

Hardwood treads, full-thickness stringers, double-mortise joinery. Our staircases meet Belgian residential structural standards and carry a 10-year warranty. With a light annual re-oil they look better at 30 years than they did on day one.

Materials

  • European oak — most common, hardwearing
  • European walnut — premium, dark luxury finish
  • Ash — light, modern, very strong
  • Pine — paint-grade, most affordable

Frequently Asked Questions

Can you fit a staircase into a tight townhouse void?

Yes — Brussels and Amsterdam townhouses often have very tight stair voids. We frequently design helical or winder staircases to fit voids as small as 1.2 × 2.0 m.

Do you do balustrades only?

Yes. We make matching balustrades for existing staircases — wood, glass, brushed steel cable.
