Case Studies - Cut string staircase between walls.


REF: 23575-slack

Notes;

Cut String staircase supplied to a self build property.


This staircase was supplied to architect Will Slack for his parents self build in York, he came to us with a requirement to have a staircase that would be cut string and sit between two walls.

A cut string staircase is where the stair treads sit on top of the strings instead of the treads going into the side of them. Using this construction method and having the stairs between walls allows for a “zig zag” effect, seen when walking up and down the stairs.

Originally specified as having no post (see customers original image), the stairs ended up featuring an offset 117x117mm newel post which was ran up to finished floor height and made into a feature, having a post on a winder means the stairs are stronger as it gives a more solid fixing on the inside of the winder box.

Will subsequently clad White Oak on top of the treads to hide any gaps between the treads and wall and also to accentuate the “zig zag” effect a stair of this type creates.

As the strings are not seen, they are manufactured using Pine, which helps reduce the cost, while solid White Oak is used for the treads and risers.

This staircase also features no overhang on the treads and a square profile which creates a seamless modern effect.

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

Other Layouts:

We also offer other staircase layouts, these include, paddle stairs, S-shape stairs, T-shape stairs or stairs with three or more turns. We also offer stairs suitable for commercial buildings which are wider and made from more substantial materials than domestic staircases.

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.

Materials:

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.
