Wooden Stairway (180° / U form)
Hey,

I am currently planning our new home and therefore looking for a wooden stairway having a U-form (180°).

I have already looked through many object bibs but did not find any. I always thought that this would be a rather standard stairway.

Thank you very much for any help.

Regards!

Jokl

..rather standard...
Yes, well, they way you describe the 180° staircase, it sounds standard. However, there are quite a few ways of making such a staircase. I put a couple of preliminary staircases in SF 3D models 329 (some other models are there already). These two are part of a collection I am working on (annoyingly, work keeps disturbing me). Alas, only with landings (which is the most common design for a 180° staircases, at least here). Use the invisible texture to hide/remove elements (handrail, balusters, riser etc). Textures can, of course, be replaced. I think the texture mapping is not too far off, but the staircases are just drafts.

The two test models are inserted in test_staircase_180_landing.sh3d. Note that my floor height is 250/265 cm, this may have to be adjusted. Hope this helps (and please let me know).

ok

Hey okh,

thank you very much. Although this is not exactly what I am looking for, it will definitely help me a lot to play around with your example.

The "u-shape" I am looking for is rather similar to example "f" in the following picture:

Why didn't you just say ? smile. Try this one (risers are hidden, add texture/colour to 'close' the staircase. U shape, UK style in my mind (narrow and dangerous). Reminds me of UK B&Bs, probably unfair. Again - test model. Comments appreciated. ok

Re: Wooden Stairway (180° / U form)
By the way, I did put some effort into making the staircases satisfy a sort of generic set of legal requirements in terms of angle, step depth (thread), ratio between thread and rise, nosing etc. Also, I checked whether staircase with similar dimensions were available as standard models. That said, every legislator seems to have an opinion on building elements (and especially staircases), which means that the dimensions may not be according to local legal requirements. Or building code may allow more hazardous approaches (e.g. in the UK steeper staircases are allowed in private homes, that would be in other European countries). ok

Re: Wooden Stairway (180° / U form)
You are so great! Thank you very much. I am going to try it out later this evening.

Hardly, but thanks anyway smile. Hope the staircases can be of use. All comments useful. Good luck. ok

Re: Wooden Stairway (180° / U form)
Here in the state I live in, Georgia - USA, the building code requires stairs to be at least 3' wide with a 7" rise and 11" step. I believe that's about it.
I could be wrong about more requirements though. I was just a lowly electrician and wasn't well versed in building codes other than electrical.

Re: Wooden Stairway (180° / U form)
Any way to have these stairs without the arrow on them? In 3D View the arrow is not there but is on the 2D planning view.

Re: Wooden Stairway (180° / U form)
I posted a new version without the planIcon, but kept other SH3D model information (including cutout M0,0 v1 h0.9 v-0.728 h0.1 v-0.272 z).

But I am curious, why would you not want the stairs direction indicator in the 2D plan? To me it is better to work with more explanatory icons.

Re: Wooden Stairway (180° / U form)
In Europe, the arrow in a 2D staircase image shows the way up. That means, the arrow starts at the lower floor and points towards the higher floor where the staircase ends.

Imagine being on the ground floor and two staircases have been inserted. This way you can discriminate between a staircase going from ground floor to second floor, and a staircase going from basement to ground floor.

Quite handy :-)

Re: Wooden Stairway (180° / U form)
As strange as it sounds, it throws me off for some reason. And none of the other stairways in the library have it. But you are right in that it does show direction the 2D Plan.

Stairways like this were used in many NYC Tenement Buildings build from the 1890s to WWII. Alas many of these old buildings are being torn down to put bigger buildings in their place. *SIGH* Memories of a long ago childhood in NYC.

Many thanks for the updated staircase!

Still curious why you do not like the planIcon with the arrow. The other staircases now available do not use customised planIcons, therefore just have an auto-generated top view. I have no strong feelings as to which is better, but personally prefer the ones with steps and direction-arrow for my own purposes.

I would hesitate to make two versions of each staircase in the planned library: one with the (proper) planIcon to show staircase and direction and one without. That would just be confusing.

Yes, I jokingly referred to that particular staircase as "UK style", dangerous, winding and narrow. Very rare here, the steep straight staircases predominant.

But please, the staircase library is pretty much complete, so I much appreciate comments on planIcons, but also styles other elements.

Re: Wooden Stairway (180° / U form)
Some changes to the semicircular staircase in library as it did not texture right and lacked handrail on one side. Also it was a bit too large for domestic use. Model has planIcon added. Some do not like them, but some apparently find them useful. This planIcon is deliberately made semi-transparent so the 2D plan will show furniture under the stairs. But if someone wants to edit, model and supplementary files in SF 3D models 329.

As the cut-out (staircaseCutOutShape#xx =m 0,1 a .5,1 0 0 1 1,0 l -0.25,0 a .25,.5 0 0 0 -.5,0 z) is a bit tricky in non-square co-ordinate systems, the SVG files are included with co-ordinate system for browser viewing. The path should be possible to edit with Inkscape (use the XML editor, to view the d-value), even if it may be a bit hard to control. (Inkscape likes to change Elliptical Arcs to Bézier curves and may convert to a mix between relative and absolute paths and many decimals - unless settings are changed. And even so, the result can be pretty frustrating).
