The Sims 4 lets you build curved fences but sadly that doesn’t apply for walls. Thankfully, Mod The Sims member maloverci created a special glass fence that comes in 5 heights. There are 3 heights that match wall heights, letting you create glass walls and curved glass walls!
Here’s what you need to do in order to create rooms with curved glass windows:
1. Download and install the Glass Fence
The glass fence can be downloaded HERE! To install it, simply extract the .zip file and paste 5 .package files into Documents\Electronic Arts\The Sims 4\Mods.
2. Plop the Rounded Deck with Fence
Select ”Walls and Empty Rooms” and find the Rounded Deck with fence (choose from any of the 3 sizes) and plop it on the ground.
3. Place the Glass Fence
Select the fences category and while in ”Replace fences” mode, select the glass fence of your height choice and click on the areas where you want to place glass fences.
4. Add another Rounded Deck on the top
Go up to next floor and plop another rounded deck right beneath the glass deck.
You can also apply these steps for for levels above.
