Knostairs. Resource and guidance site.

Take one of our 3D models for a spin at the bottom of the page.

We have more of these throughout the site.

We will use these models when it helps to explain or visualise the subject.

Keep an eye out for the 3D logo.

Staircase work on site.


A look at the type of work that you may come across on site, from fitting the stairs and handrail, to modifying them, repairing damaged handrail.


We will have articles on some of the projects we have completed and live projects as we work through them. There will be general notes on the obstacles to look out for and how to get around them.

As this is a side of the work that I enjoy, there will be an amount of articles that will relate to the repairing, adjusting and extending tradtional stairs and handrail.

Such as how to design an addtional flight to match the existing.
