2. So far, The Sims 4 only offers the standard stair. However, that could change if a recent social media post from a Sims producer is any indication. Sims 4 L-shaped Stairs; Sims 3 L Shaped Stairs Download Torrent; Sims 4 Stair Mods; Creating an L-shaped staircase with and without a foundation in the Sims 3 is a relatively easy process.

Sims 3 Modded Script Stairs - Cottage Half Landing. A joint project between Inge and Gosik. The point of creating these stairs is that they do not require stages, foundations, or dummy CFE levels to create the landing effect, and therefore no wasted building levels or warped walls.

A Note: As far as I know, there is no cheat to make it so friezes can be placed on ground floors. For that, you should probably just do the traditional way to making modular stairs. Also, these stairs will not be equal length, so if you suffer from video game symmetry OCD, avoid this tutorial!
Friezes are a feature in Ambitions that allows you to place foundation height walls on top of normal height walls without having to go through the 'constrainfloorelevation' cheat. They are acessed through a cheat called 'placefriezes on/off.' Friezes are created by going into the foundation menu, clicking the traditional brick foundation and dragging it across an upper level with a floor. Friezes cannot be placed next to walls unless you used the 'constrainfloorelevation' cheat.
Games Needed:
Ambitions
Cheats Used:
placefriezes on/of
constrainfloorelevation false/true
Step 1
Create the shape of your house and plan where you want you rooms and stairs to be.

Choose your stairs and place it in the flat section of the L.
Step 6
Open the cheat menu again and type 'constrainfloorelevation false' (remember to open the cheat menu again when you're done, hit the up key and replace false with true.) Choose your stairs again and place them by holding the stairs close to the third floor.
Other Shapes
Instead of doing U shaped modular stairs, you can make L shaped modular stairs by doing all the steps above but replacing the L shaped frieze with a basic 1x2 frieze.
You must do a 1x2 frieze. Although you can place modular stairs on a 1x1 frieze, it won't work in-game. Also, it looks stupid.

These stairs here are the scripted version of the stairs Gosik and I made from the Generations EP spiral stairs. Gosik made the mesh and textures, while I made the script and edited the routing slots and rig. We both edited the footprints and nearly had a fight over what should be allowed to intersect, but managed to compromise in the end lol! The scripted version stops the sim animating, which looked silly as he was going round in a spiral (he now just snaps from the bottom to the top instead of walking up) and also disables the sliding down rail interaction. The entire unscripted (uses EA's spiral stairs script) set as Sims3Pack can be downloaded at http://www.thesimsresource.com/downloads/1115099 The set includes the removable base infill, and the wall-like fences that fit under the slope of the stairs. However, because the launcher will no longer install scripted items as Sims3Packs, the modded versions of the staircases are offered here as packages. They have their own ID so you could have the Sims3Pack versions and these both in your game at the same time.
