New The Sims 4 Build Features Noticed in Royalty & Legacy Footage

Players uncover interesting Sims 4 features shown in the official Sims 4 Royalty & Legacy footage!

The Sims 4 Royalty & Legacy is the 21st Expansion Pack in The Sims 4 Series. Presumably just like with the previous Sims 4 Expansion Pack releases this one will be followed with new features. More will definitely be revealed as we get closer to the February 12th, 2026 release date, but the Sims community has already been talking about these new Sims 4 build features that we can't help but wonder. Are they really coming to The Sims 4?

Let's break them down below:

Sweeping Stairs and Customized Railing Addition

Players have discovered a new type of stairs in two different frames from The Sims 4 Royalty & Legacy Expansion Pack. They're described as "sweeping" stairs, as they include a round edge / corner with matching trims.

Player @SerXefrosTritoh discovered these, along with what appears to be more customizable railings in The Sims 4. Do you notice how they end halfway the stairs?

The new Sims 4 stairs have later been shown in The Sims 4 Ondarion World Reveal with the Bellacorde Palace! See a closer look below:

Single Railings

Discovered by @phii_oda, it appears The Sims 4 is getting single railings. Currently in The Sims 4 you can only place double railings automatically on configurable stairs or no railings at all. This footage appears to show no railing on the other side of the configured stairs:

are those single railings?

This setup can be seen in a larger picture also from The Sims 4 World Reveal trailer:

New Lot Types

These are 99.9% most probably exclusive to The Sims 4 Royalty & Legacy Expansion Pack. We're talking about the two new Market and Backrooms Lot Type!

The first icon preview can be seen from The Sims 4 Ondarion World Map Reveal. The new lot icon on the left seems to be the Backrooms lot type while the one on the right is the new Market lot type.

The backrooms lot type was announced already, but there's a new market lot type too, built by @EmeraldStorie!

We currently have no previews of The Sims 4 Market Lot Type, but we're probably getting to know more in the Noble Gameplay Trailer premiere coming this week. We have some fun facts about the Backrooms Lot Type featured in the reveal blog:

The Backroom Lot, a new Lot type, leads a double life. By day, it functions as a Library, Gym, or Museum depending on how you build it, but when night falls, it transforms into a Night Club. Sims can experience this shift in Dambele, home to a premade Backroom Lot that trades quiet study for nightlife after dark.

    I guarantee those stairs and railings will be glitchy for a month or two after launch. Anything new is always broken upon release. Its just the standard for this game. Curved walls, curved pools, terrain tools, basements, and lot traits were all glitchy when they came out in some capacity.

      And by that time most simmers won’t care anymore because the novelty will wear off. Rinse and repeat. Consoom pack and get excited for next pack.

    So let me get this straight.

    According to an “insider” (or at least previous insider), things like spiral stairs are scrapped forever cause they weren’t used much in TS3 by us players and the cost of giving us those in TS4 would give EA no money in return.

    However, sweeped stairs and a stairrailing update which are most likely to come in base game with the pre-pack patch for FREE, IS profitable? [Considering we already had a huge free stairs update in the past]

    You see how this already debunked that TS3 user data leads to previous content not comingback to TS4 as EA sees it as unprofitable rumour……………

    Not trying to be shady or mean but I mean, that rumour already made zero sense before this.

      Yep, I don’t think the insider knew what they were talking about, honestly. Just a load of rubbish.

    Are we getting a new stair type or did they add a slider for the sweeping look? Excited either way!

    This find of stairs is ok but I guarantee they will be HUGE again!! I want SPIRAL STAIRCASES!!!! Did you ever try and put a straight or evan a configured staircase in a ROUND BUILD?
