While there isn't always a single "plug-and-play" script mod that safely changes the hardcoded user interface permanently without breaking during game patches, the most reliable tool for advanced building is by TwistedMexi.
Raise items and structural elements way past the standard four-story ceiling.
If you decide to go the modded route to expand your building capabilities, follow these steps to ensure your game doesn't crash: sims 4 build more than 4 floors mod
On an empty area of the lot (or on the fourth floor), build the individual components—like half-walls, platforms, pillars, or decorative objects—that you want to use for your fifth floor and beyond.

Unlimited roof heights are another fantastic way to add vertical interest to a build. By raising a roof to its maximum height, you create a massive, hollow upper volume. Inside this volume, you can place interior rooms, stairs, and lofts, effectively turning a roof cavity into an additional "floor" that doesn't count toward the game's limit.
The most effective way to build structures that appear much taller than four stories is by using the mod by TwistedMexi. This mod is a staple for advanced Sims 4 builders. How it Works | Cheat Code | What It Does | | :--- | :--- | | bb
Here is the detail that makes this mod essential for storytellers and stylist builders, even if they don't want to build a 50-story tower.
Sims will take forever to navigate verticality. They will get "stuck" in the logic of stairs. This mod essentially forces you to treat the building like a movie set rather than a functional home. You build floors 1–10 for aesthetics, but you likely only let your Sims live on floors 9 and 10, treating the lower levels as a decorative base.
If you want a stable way to build high without fighting the game engine constantly, mods are your best friend.
