Thanks Michel

I’ve decided to go with the central cutstringer, horizontal laminate technique. I watched the video on how to draw the laminates in ProgeCAD. It starts with exporting a 2D DXF from StairDesigner. What’s the best way of creating the central cutstringer in StairDesigner, please?

Hi Stu,

I saw your drawings and both types of stairs are possible ( central cutstringer or lateral cutstringers).

both can be created with the horizontal laminate technique and we have some videos on the website showing the build. So it is a matter of taste. 

With the central custringer you need a firm and strong connection on base and top to have good support for the complete stair. With the lateral custringer you have a possibility of a connection point on the wall side (mid stair) to add support for the stair, but is also possible without wall connection but here then also a good floor and top connection is needed.

Hi Stuart, thanks for posting. I’ve actually moved your message to the stair building forum, so one of our technical team can take a look. All the best…

I’m Stu. I’m buying the shell of a house to fit out myself, and I’m going to need a stair! Also going to need a fitted kitchen, two bathrooms, shelving for two walk-in wardrobes…

So, I’ve had a play with StairDesigner, which I have to say seems pretty impressive! At this stage I’d appreciate a discussion about whether the things I’m designing would stand up. The Architect’s plan calls for a stair that isn’t attached to the walls.

I’d also like to talk about construction methods and materials. I was initially drawn to your technique for the single stringer stair, but now I’m not so sure.

I have some links to images:
