Long hallway with a wood floor leading to an open stair with wood treads, cable railings and tall wood fins along a window wall

Stairs. The room between floors.

Open treads, steel, glass, oak and concrete: a stair that brings daylight down through the house and becomes its centerpiece.

More than a way upstairs.

A stair is often the largest single piece in a house, and one you use every day. We design it together with the rooms around it, so it can bring daylight down from above, frame a view or divide a space without closing it off.

Rise, run, headroom and railing heights are worked out with the building code from the first drawings, so the stair that is approved is the stair that gets built.

Our approach

Structure, light and craft.

A black steel spine carrying oak treads behind frameless glass, concrete treads that float off a white wall, or a screen of oak slats that lets the light through: each stair gets one clear structural idea.

Railings are part of the design from the first sketch, in glass, steel cable or wood, so they meet the code without hiding the stair.
