Case Studies - Cut string staircase between walls.

REF: 23575-slack

3D Model;

Notable Features:

Cut String Between Walls:

With a cut-string staircase, rather than the treads & risers being housed in the string, they sit on top of it, creating a feature. However, this is usually done to enhance the staircase's side profile. As such, it's unusual to have a cut-string staircase between two walls. However, the effect is still visible from above when walking down the stairs. To reduce cost, the client also used pine strings, which wouldn't be visible.

Feature "Zig-Zag" trim:

Having a cut-string against a plastered wall creates a problem in that the plastered wall will often not be totally flat, resulting in unsightly gaps between the wall and the string. The client opted to use a trim which resolves this problem.

Four Kite Winder:

A kite winder stair usually contains three kites. Primarily this is because it's hard to get the inside corners of more than three kites into a post. However, on this staircase, we've used a 115x115mm inside post to overcome this problem.

No Overhang, Square Profile Treads:

For a modern look, square-edged treads were used on this staircase with no overhang past the riser.

Customer Feedback

We are very happy with the service and quality of stair provided by TK stairs. The white oak cut string with square profile seamlessly integrates with the contemporary aesthetic of the house. We did end up chamfering the square profile as it was a little too sharp! - Will Slack Architecture & Design

Styles & Materials

Construction Methods:

All layouts of staircases can be constructed in different ways which will effect the final finish, these include:

  • Open riser construction; this is where the risers are left open with either a timber strip or metal bar built in to comply to regulations.
  • Cut string construction; where the sides of the strings are cut away so the treads can be seen, this can either be done in a modern or traditional way.


The materials used on your staircase will have a dramatic effect on how they look, most stairs will use the following materials.

  • Pine; all our stairs are manufactured from high quality furniture grade pine, we do not use any whitewood.
  • White Oak; we can manufacture all or part(s) of your staircase from premium White Oak, to give that stunning finish.
  • Glass; we offer stairs with glass balustrade, either as small panels or large panels, secured with brackets or by embedding with a groove.
