This wikiHow teaches you how to build a house in The Sims 3. If you'd prefer to use a house that someone else built, you can download a template from The Sims 3 Exchange instead.

Method 1

Method 1 of 2:

Building from Scratch

1
Determine the type of house you want to build. Before you dive into creating a house in your game, you should know the style and general appearance you want to use. Other things to keep in mind include the following:
- Number of stories
- Approximate size
- General materials (e.g., wood, brick, etc.)
2
Consider using a model. Using a real house as a basis for your Sims 3 house's exterior can provide a useful guide in case you're having trouble visualizing what you want your house to look like.
- You can find images of houses on real estate sites such as Zillow, or you can simply search Google's images section for pictures of a particular style of house.

3
Select an empty lot. Click a lot on which you want to build your house, then click the paint roller-shaped "Build" icon in the resulting pop-up menu.
4
Familiarize yourself with the Sims 3 house-building interface. Once the lot opens, the building tab will open at the bottom of the screen; you should see a diagram of a house, along with various house components, listed there.
- Selecting a specific piece of the house diagram (e.g., the roof) will bring up a list of building options related to the component (for example, clicking the roof will cause several different styles of roof to appear).
5
Even out the ground. Click the mound-shaped "Terrain Tools" icon in the house diagram, then click and drag across your lot to select the whole thing before you release the mouse button.^{[1]

6
Create the foundation. Click the foundation icon below the house diagram, then click and drag across the lot. This is the base on which your house will rest, and it will determine the shape of your house.
- If you want to make an irregular-shaped house (e.g., a house in the shape of an "L"), you can add a piece of foundation to the main foundation by clicking and dragging another section of foundation to connect to the main one.
7
Add walls to your foundation. Click the house diagram's wall (making sure not to click the window instead), then click and drag your wall all the way around your house. This will create the first floor's outer wall.
8
Partition your first floor's rooms. Using the wall tool, click and drag from the outer wall inward to create dividing walls.
- Examples of rooms you may wish to create include a kitchen, bedrooms, and a bathroom.
- This step isn't necessary if you want to create an open floor plan, though you'll still most likely want to partition off the bathroom.
9
Add details for each floor. You can change the appearance of your house's floors by doing the following:
- Click the floor icon in the house diagram.
- Click the second tab from the left at the top of the diagram area.
- Select a texture you want to use for your floor.
- Click and drag across the floor.
10
Detail the walls. Much like you did for the floors, you can add textures, wallpaper, and more to your walls:
- Click the wall icon in the house diagram.
- Select one of the tabs at the top of the wall section.
- Click (or, depending on the texture, click and drag across) the wall.
11
Add and decorate a second floor if needed. To add a floor to your house, click the floor section (above the foundation) of the house diagram, then click and drag across your house's outline.
- You can repeat this process to add subsequent stories as needed.
12
Add doors and windows. Click the door or window icon in the house diagram, then select a part of your house to add the door or window, then repeat as needed.
- You may first want to select a different door or window preset in the toolbar at the bottom of the screen.
- You can also add doors to walls inside your house.
13
Put a roof on your house. Click the roof icon in the house diagram, then select a roof template and click and drag across the top of your house to apply the roof.
- If you want to add intersecting roofs to extend your roof to cover an extended part of the house, you can repeat this process by dragging a new roof perpendicular to the existing roof.
14
Apply textures to your house's exterior. The final design element for your house is the exterior appearance. You can change the way your house's outside walls, doors, windows, roof, and other aspects look by doing the following:
- Select the part of the house you want to detail (e.g., the door or the wall) in the house diagram.
- Click a tab to view available textures (e.g., Paint).
- Select a texture.
- Select the part of the house to apply the texture.
15
Decorate your house. Now that your house's structure is complete, all that's left to do is add furniture, interior decorations, and any other details you want to apply. You can do this by clicking the furniture tab above the "Build" tab at the bottom of the screen, selecting different tabs to view their related pieces of furniture or decorations, selecting a piece of furniture or decor, and selecting a space in your house.

Using a Template

Open the Sims 3 Exchange site. Go to thesims3.com/exchange/lots in your computer's web browser.

- If you haven't yet created a Sims 3 account, click the Join Now for Free link in the top-right corner of the window, then follow the on-screen instructions to create an account.

Browse the available houses. Near the bottom of the page, you'll see a list of available house templates; you can click a house's thumbnail to view it at the top of the page, and you can skip to the next page of templates by clicking the page number in the top-right corner of the house preview section.

Select a house. Once you decide on a house, click its thumbnail in the house preview section to open it.

Click ADD TO GAME. It's to the right of the house preview. Doing so will open The Sims 3's launcher in a new window.

Click the Downloads tab. This option is on the left side of the launcher window.

Make sure the house's box is checked. If you don't see a check in the box to the left of the house's icon in the launcher window, click the box to check it before proceeding.
8
Click Install. It's at the bottom of the launcher window. The house file will begin adding to your Sims 3 game.
9
Uncheck the "Run without custom content" box. This box is at the top of the launcher window.

No, you can just remodel that part of the house.
