1.) Slide Down Error Fix for Custom Stairs and Ladders by Lamare

With this global fix sims won’t cause errors and jump bugs trying to slide down the custom stairs and ladders. When a sim is considering sliding down, the game checks if the type of stairs is OK. Most, if not all, custom stairs are not so with this mod a list of approved for sliding straight stairs that include all the Maxis ones, except for “Step It Up” Pyramid that has no railings (it was originally excluded, too).f

2.) Slide Down Stair Railing Enabled by Squinge

This mod enables the slide down stair railing interaction for all sims.

3.) Fake Floor Landings by Sim Logical

These “landing” objects allow you to get rid of the warped walls and unlevel floors for the situations when it is important to have your wallpaper and windows undisturbed. They allow your sim to assume there is some floor he can walk on, even when you have levelled the floor back down and removed the floor tiles that are visually at the wrong level.  Please note, at each fake landing your sim will briefly drop to the level of the real floor grid before jumping back up and carrying on using the stairs.  You need to weigh up the pros and cons – form.v.function

How to use

4.) Half Landing Stairs by Sim Logical

This is a normal (non-modular) staircase for if you want a half landing without using dummy levels or warped walls. Custom non-modular stairs rarely have working animations. Your sim will begin in the right place and end in the right place, and sort of zap between them without walking. You will need to use move_objects to place the stairs in some positions.

5.) Stair Runner by Sim Logical

The point of this object is to make it possible for your stair carpet to match your hall carpet.  Does not fit modular stairs. The rods and the carpet are separately recolourable.  This set of runners is based on the “repository” technique which means if you make a recolour for the straight runner, it will act as a recolour for all the runners. 

6.) Winding Stairs by Sim Logical

This is a normal (non-modular) staircase with winders at the top and the bottom. The sim starts and ends where you would expect for the shape of these stairs so you can build your walls accordingly, but he does get there a little bit funny (if you look carefully at one time you can see him come through the landing floor. But it happens so fast it needn’t spoil your enjoyment.

The banisters are the upwardly mobile. There are no railings going up the wall side, as the stairs are meant to go against a wall, so the ones at the bottom go down when you use the tool to remove the left railings, and the ones up the edge are counted as the right railings.

You’ll have to use move_objects cheat to place the stairs.

ijWindersCW_um -Stairs turn clockwise
ijWindersAC_um – Stairs turn anticlockwise
ijStairsMatchingfence – Sunni Sims’ fence coloured to exactly match the colour and height of the stair rails.

7.) Wallpaperable Star Walls by Sim Logical

Actually this download isn’t walls at all, it’s windows!

These are wall cutouts with a recolourable trim, to cut the walls out at graduated staircase height, which leaves the lower part of the wall only showing. And of course you can paint or paper that wall to match your others. ijStairwall5snip smooths out where the openings go through floor level, because otherwise a corner of the lower wall sticks through them.
