Build Mode — the feature that wins outright

Build Mode is the single Paralives feature that even cautious reviewers agree beats The Sims 4 cold. The TL;DR: grid-less placement, curved walls, split-level floors, and “resize and recolor anything”. This guide walks through the architecture of Build Mode and how to use it without fighting the tool.

Source-credibility note. This guide draws on paralives.wiki.gg/Build_Mode, Alex Massé’s Patreon dev posts on building, and the official Paralives YouTube channel’s Build Mode showcases. Mechanics are correct as of EA launch.

What “grid-less” really means

The Sims has always built on a grid: walls snap to 1-meter increments, floor tiles are squares, room shapes are rectangles unless you cheat with mods. Paralives drops the grid entirely.

Walls can go at any angle.
Walls can be curved (you drag a Bézier-style handle).
Floors and walls don’t have to align — you can offset a wall halfway through a “tile”.
Furniture places at any position and rotation, not just at 45° snaps.

You still get snap helpers (hold Shift to snap to a 90° angle, etc.) — it’s grid-less, not snap-less. But the snap is opt-in, not the default.

Split-level floors

Sims 4 added platforms in 2022 as a hack. Paralives ships proper split-level floors at EA:

Half-storey landings between floors.
Sunken living rooms / raised platforms within a single room.
Multi-level patios.
Skylights and clerestory windows that respect the level geometry.

The four-tab catalog (and the search tab)

Build Mode’s catalog has 4 main tabs + 1 search tab:

By room — bedroom, kitchen, bathroom, etc. (matches Sims convention.)
By function — seating, storage, lighting, decor. (Good when you know the type but not the room.)
By style — modern, rustic, mid-century, etc. (Good when matching a vibe.)
Build elements — walls, floors, roofs, windows, doors, stairs.
Search — text search across all of the above.

Resize and recolor anything

Almost every object has at least two sliders:

Scale — make a coffee table 1.4x its base size, a couch 0.8x.
Color — full color wheel + hex input on every recolorable surface.

Some objects have more (e.g. tables can have leg styles swapped independently of top surface).

This means you don’t need 17 versions of “modern lamp” in the catalog — there are a few base lamps, and you make them yours.

Recommended workflow

For a lot built from scratch:

Block out the building footprint first — walls only, no roof, no floors yet. Use grid-less to position walls at intentional angles (not snap-90s) for visual interest.
Drop in roof shape before furnishing — roof geometry constrains second-floor wall placement.
Place big anchor furniture (sofa, bed, dining table) before walls of small items. You’ll resize the room to fit, not the other way.
Lighting last — lighting on an empty room hides nothing; lighting on a populated room reveals what’s working.
Recolor pass at the end — color decisions are easier when the room composition is locked.

Performance notes

The grid-less engine is more expensive per-frame than Sims 4’s grid renderer. If your machine is at the minimum spec, plan for 30 FPS in Build Mode and 45-60 FPS in Live Mode.
Lots over ~5,000 placed objects start to chug on minimum-spec hardware. Recommended-spec machines have headroom for ~10,000+.

What’s missing in EA

Pools — confirmed for post-EA free updates, not Day 1.
Underground / basement levels — coming later.
Curved roofs — straight-line roofs only at EA; curved roof tools are roadmap.
