The Sims 4: Complete Build Mode Guide for Beginners

Opening an empty lot and coming face to face with the Build Mode of The Sims 4 is often the beginner's great vertigo: where to start, in what order to place the walls, where to find the pool? This guide walks through every step to build a clean first house, from choosing the lot to the finishing touches, without forgetting the essential cheats and keyboard shortcuts that save hours.

Switching to Build Mode and choosing your lot

Build Mode can be activated at any time by pressing F3, or by clicking the hammer-and-wrench icon in the top right of the screen. You then leave Live Mode and the clock pauses: perfect for taking your time without a Sim falling asleep on the floor.

Before drawing the slightest room, choose your starting point. Two paths are open to the player:

• Editing an already occupied lot: the budget is drawn from the active household's funds. Ideal for expanding the existing house of a Sim you're playing.
• Going through Manage Worlds and clicking on an empty lot: construction is then "free," all career reward objects are unlocked, and you don't touch any funds.

A 20x15 lot is the ideal size for a first house: it fits within the starting budget of §20,000, it stays compact, and your Sims' routines flow through it with ease.

Foundations, walls and floors: the skeleton of the house

Once on the lot, the logical order is always the same: volumes first, decoration second. Select the Foundations tool and lay the slab that will define the livable area. The side arrows adjust the height: a raised foundation gives a more realistic villa look and leaves room to slip in a crawl space or a basement afterward.

Then trace the facade walls with the Wall tool. Don't think about the interior rooms yet: focus on the shape of the building as seen from outside. To add a floor, click the upward arrow on the right of the action bar; a second floor appears, on which you repeat the layout. The game automatically handles the modular stairs you'll place afterward, and you can always come back and move an entire room along with its furniture using the selection tool.

Roofs, doors and windows that add style

The Roofs tool offers several shapes: flat roof for a modern look, classic two-sided gable, hip roof for cottages, dome for exotic buildings, or even pagoda. Once the roof is placed, blue handles appear on its edges, letting you adjust the slope, the angle and, above all, the curve. This is where the true architectural character comes into play: stack several sections to create attic dormers, turrets, or French-style mansard roofs.

Next, place doors and windows. Each model comes in several styles and heights (small, medium, panoramic). Once placed, a window can be shifted up or down with Ctrl + 9 and Ctrl + 0, and moldings (friezes, baseboards, cornices) can be chosen from a dedicated tab to dress up your walls.

Limit yourself to two opening styles maximum for the whole house: too many different models and the result starts to look like a patchwork.

Flooring, wallpaper, and objects by room

Next, move on to covering surfaces. The Floors tab organizes hardwood, tile, carpet, and stone by mood. The Walls tab lays out paint, wallpaper, exposed brick, and wainscoting. Two shortcuts worth remembering to speed things up:

• Alt while clicking: applies the covering to the entire wall at once, without having to click segment by segment.
• Shift while clicking: applies the texture to the entire room simultaneously.

The object catalog can be sorted by room (kitchen, living room, bedroom, bathroom) or by function (storage, lighting, decoration, plumbing). Sorting by ascending price or by style is available at the top of the panel, which helps stick to a tight budget. The eyedropper (press E) copies the color of an existing object, and the design tool (press R) applies a color variant with one click to harmonize an entire room.

Grid, cheats, and tools that change everything

The Build Mode grid locks objects onto fixed tiles, which guarantees a clean result but can hamper creativity as soon as you want to push two pieces of furniture together or offset a painting. Three shortcuts are enough to tame it:

• Hold Alt while moving an object to completely disable the grid and place it with pinpoint precision.
• Hold Shift to adjust the height of a wall-mounted object (shelves, paintings, wall lights).
• F5 key: toggles between half-tile and quarter-tile grid for finer placement.

Open the console with Ctrl + Shift + C, type testingcheats true, then the essential command for Build Mode:

• bb.moveobjects on: places objects anywhere, even on top of each other, with no collision constraints.

The full list of building cheat codes, including the rotation cheat, is detailed in our Sims 4 cheat codes guide.

Pools, basements, and garages: the extras that make the difference

The pool is dug directly with the dedicated tool: draw a rectangle on the lot and the game automatically generates ladders, coping, and the swimming routine. You can raise the pool onto foundations, add windows to its side walls, and get a panoramic aquarium worthy of a vacation resort.

The basement follows the same logic: select the tool, trace its footprint under the house, then go down a level via the side arrow to fit out a laundry room, gym, or hidden room. For a garage, draw a wide enough room and place a garage door: official expansions then add usable cars, but the structure itself is still built in base Build Mode.

EA Gallery, beginner tips, and sharing your creations

The EA Gallery is an unbeatable shortcut for players in a hurry: in-game, press the G key to browse community creations. Filter by lot type, price, style or popularity, tick the box to exclude custom content (CC), then click Place on Lot to instantly import the house straight into your game. Handy for a first home, or simply for inspiration on a façade.

A few survival rules so you don't get lost as a beginner:

• Start small: a 5x5 studio with a kitchen, bathroom and bed is worth more than a fifty-room empty mansion.
• Cover vital needs: fridge, stove, sink, toilet, shower and bed. Without them, your Sim gets depressed within a few hours of play.
• At least one door per room, and plan traffic flow before decorating: nothing worse than a dead-end hallway.

Once your house is finished, save it and publish it: our tip on how to save and share a Sims 4 house covers every step, from your personal library to publishing on the Gallery.
