Hi Ness anchor position is 17 cm and floor thickness is 34.6 cm
I do not understand the anchor position but hope you can get something out of what I have written
I have made a landing step and put in the right measures they are 265,1 cm and 282 cm
so now I think I'm done and if you do not have anything to add, you can send the files

Hi Jesper,
This stair doesn't have a landing step and is not the last version I have.
I attach the last version which has a total height of 2648, compared to the version you just posted at 2640.
Note that it's usually better to make the stair a little higher than shorter.
Note also that the vertical width of the cut string as it meets the joist is 384 and the anchor height where you'll have to fix the stringer into the joist is in the lower half of this. So you have to check the total floor thickness and make sure that this is possible given the position of the main supporting timber .
Can you make any necessary adjustments to the stair I'm posting and validate the project for processing?
Hey Ness, I think this is the final design but I'm not quite sure 🙂 do you have anything to add? the stair are maybe 3 mm higher but if I press it into the program so it will have 15 steps and I would rather avoid

Hi Jesper,
Before I send you the manufacturing documents and so that there is no confusion in the file we process, can you post your final and validated project sds file to the forum.
yes I'm a little busy because my bank is up my ass ? but that's okay it will not be this week. but I hope it may be early next week?

The StairFile order has come through, thanks for that. We will review your project as soon as possible, I realise you're in a hurry but unfortunately it may not be this week now. Best regards, Stefan
Hello Ness now I am ready to continue with my project.
here is a picture of the joist we talked about last time.
but how it is set up does not really matter because the stairs are closed below.
when do you think that I am ready to continue staircase file.
because I need to use the drawings as soon as possible
All the best jesper

Hi Jasper,
Landing steps are usually less wide than others.
The exact width depends on how you want to connect the stair with the upper floor level.
The way you connect the stair depends on the stair elements and the upper floor configuration.
For cut strings the landing step width is very important as it will determine how the sting meets the floor joist.
The wider the landing step the higher the lower sting edge will meet the joist:
In the above drawings the left stair has a narrow landing step that makes it difficult to assemble the string to the joist.
The right stair is what I consider the best situation where the lower string edge meets the face of the joist. This then determines the right width of the landing step. However this often means that the landing step is fairly wide and reduces the total tread line which can be a problem if the stair well is a tight fit.
You have to bare in mind that you must assemble the structural lower part of the string to the joist or first floor, so in the left stair you will will either have to extend the string under the ceiling:
or use a hanging bracket or post.
This type of assembly reduces the width of the landing step and maximises the tread line length.
In your case you have plenty of room so you can set the landing step to the width that you want.
To determine the ideal width of the landing step you should make a drawing of the arrival with the string and the joist height.
If you want me to do this, I'll need to know if you have a newel on the end of the string, what elements are around the stair well at the first floor level (assembly with eventual balustrades or railings) and the joist height.
Sorry to reply so late, but I've been away on a trade show the last week.
For your stair, unfortunately you can't make the risers shorter in StairDesigner.
To do this you have to modify the DXF files or the production drawings by hand.
As well as this for this type of stair I would suggest that you make the risers sit on the step and eventially notch the back of the steps into the cut strings like this:
Once the StairDesigner model is set up like this you can manually reduce the riser lengths.
The risers can be just screwed from under the step as in the above image or grooved into the step like this:
In this case you'll have to also reduce the groove length to suit.
The easiest way to check the different heights and clearances is to make a SketchUp model and insert the StairDesigner 3d DXF file.
I've set up and attached a quick model for you :
As you can see from the model your stair will fit neatly into the corner with no problem.
However I see that you don't have a landing step, is this done on purpose?
In general I alway suggest using a landing step if possible.
I attach a StairDesigner model jesper02v01.sds as an example of how I would set up a stair like this.
All the best,
Ness
The following users say thank you to Ness for this useful post:
Hello Ness I have a problem with risers I want that they only go out to the cut strings so the steps floats in the air if possible
I also need some measures on the stairs because I have a window at the bottom of the stairs which I hope I do not hit
I hope you understand what I mean, I understand if you do notI have attached a sds file but it is only 3 kb so I do not know if it can be opened
