Case Studies - Cut string half turn staircase white an oak and white paint finish

REF: 37332-brann

3D Model;

Notable Features:

Cut String - Traditional:

Cut string refers to a construction method where the stringers are cut away in a 'zig-zag' fashion when machined. A wider stringer is necessary to give the strength needed for this to work (90mm wider). The spindles then sit on top of the treads; no bottomrail is required on the stairs.

With cut-string staircases, there are a lot of different variables that can affect the appearance of the stairs.

White Painted & Oak Combination:

Oak stairs are timeless and ever-popular. However, sometimes it's great to break it up with some colour. Painting some components of the stairs, either white or another colour, is a popular option.

The other advantage of this is that the components that are going to be painted do not need to be oak, which saves money. The end result is often just as striking or can look better to some eyes.

Pencil Rounded Treads:

The standard way to finish the front of treads (tread profile) is a "full round", so the entire front and side would be rounded. On these 32mm treads, we'd use a 16mm radius.

However, for this stair, the customer opted for "pencil round" treads, so an 8mm radius round is applied. This is generally considered to be more modern in appearance. 

Handrail Into Ceiling:

When there's a handrail on the stairs, we recommend that the stairs are 100mm narrower than the opening to allow adequate space between the handrail and the opening. 

However, given that these stairs were to go into an existing opening and, if we did this, the stair would end up 780mm wide on flight two. The customer opted to have the stairs the entire width of the opening.

We do not recommend this, as the handrail will clash with the ceiling, as shown in the pictures. 


Customer Feedback

We are totally delighted with our new staircase. TKstairs were very helpful when designing the staircase. We opened up the downstairs in our two bedroom house to provide more space and wanted the stairs to be a feature in the room, but we had minimal space, which made it a challenge. The quality of the staircase is fantastic, and the finished look is fabulous. - Ms Brann

Paddle Staircases:

Also known as space saver or loft staircases, these are half the length of a normal staircase but can only be used in certain scenarios.

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.


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.
