TL;DR — diagonal building at a glance
- Straight walls place freely, without following a set grid — so a wall can be drawn at any angle, along with half-walls and fences (the wiki's Build Mode overview, citing the official 2019 placement demo).
- Diagonal flooring is officially on record: in the dev chat of May 13, 2022 the studio answered that players will be able to rotate flooring in all directions and that diagonal flooring "shouldn't be hard".
- The same dev chat said wraparound porches "should be doable" — a 2022 plan statement; today's porch builds assemble platforms, railings and stairs.
- "Slanted walls" often means the sloped ceiling plane of an attic room — that is roof geometry, not a wall angle; our attic and roofs guides own that job.
- Two wall tools, one split: Draw Curved Wall bends arcs, Draw Straight Wall draws your diagonals — and the grid toggle (G) stops snapping when you want a purely free angle.
Drawing diagonal walls: free placement is the whole trick
The wiki's Build Mode overview groups walls, half-walls and fences as pieces you can "place freely, without following a set grid", citing the studio's official 'Paralives - Curved Walls and Split-Level' video from July 2019. For the straight wall tool that freedom is the diagonal feature: click a start point, drag along whatever angle your plan needs, release — the preview follows the cursor, not an axis.
The tool table on the same wiki page names the three tools this page turns on: Draw Straight Wall, Draw Curved Wall and Toggle Grid On/Off. The grid toggle lives on the G key in build mode — press it and placement stops snapping to the grid; press it again when you want new segments to land cleanly on the edges of an existing room.
Two habits make diagonals easier: start an angled run from an existing wall's endpoint so the joint seals (a room registers its floor once its walls close), and hold Alt (hold) for free placement when a point refuses to sit where the plan needs it — the same fallback our walls guide uses for off-grid prebuilt homes. The B key is the documented shortcut for the wall tool itself.
Diagonal flooring: what the studio has actually said
A diagonal floor is a different mechanism from a diagonal wall: the ask is to rotate a floor slab so it reads as a diamond against the grid. In the studio's dev chat of May 13, 2022, the official answer was that "players will be able to rotate the flooring in all directions" and that "it shouldn't be hard to create diagonal flooring" — as relayed in Catchy's summary of that chat. Treat both quotes as the official plan as of that date, not as a documented walkthrough of the current build.
Rotation itself is a core placement mechanic: the official 'Resize, Stack and Flip Objects' video (September 2019) shows objects rotating and resizing freely, and build mode's documented rotation bindings — X for a 90-degree turn, , and . for 45-degree steps — come straight from the controls page. How far flooring specifically answers to those bindings in 0.1.8b is not documented, which is exactly what the unverified section below is for.

The same May 2022 dev chat took the classic diagonal-adjacent request — wraparound porches — and the official answer was that they "should be doable". That, too, is a plan statement from 2022 rather than a tutorial promise. In the current build, porches come together from deck platforms, railings and stairs, and an angled porch edge is drawn the same way any diagonal is: free placement, off-axis.
If a wraparound is the goal, our porch tutorial keeps a dedicated wraparound variant walkthrough alongside the deck and screened versions — raised platforms, railing finishes and the stair connections that make the ring walkable.
Read the porch tutorial"Slanted walls" usually means something else (attics)
A large share of slanted-wall and sloped-wall searches are really about the sloped surface under a roof — the wall that seems to lean because the attic's roof plane cuts through the room. That surface is not drawn as an angled wall at all; it is what the roof geometry leaves behind, and it is why an ordinary vertical wall keeps clipping into the roof above.
If the goal is that cozy half-storey look, the attic room guide is the page that solves it — it walks the roof placement trick that stops the clipping. If the question is really about roof shapes themselves — hips, gables, why a roof refuses to generate over an odd footprint — the roofs guide owns that.
The one-line split: a diagonal wall is a wall you deliberately draw off-axis (this page); a slanted wall is the sloped plane a roof creates above an ordinary room (attic and roofs pages). Searching with the right word gets you to the right workflow in one hop.
Read the attic room guideDiagonal walls vs curved walls: which tool does which
Paralives ships two wall tools, and the wiki's tool table names both: Draw Straight Wall and Draw Curved Wall. The split is exactly what it sounds like — the straight tool is the one that draws diagonals, because grid-free placement lets a straight segment run at any angle, while the curved tool bends into arcs for round towers and soft facades.
A rule of thumb for mixed builds: if the line runs in one direction from end to end, it is a straight-wall diagonal; if it changes direction continuously along its length, it is a job for the curved tool. Real builds often combine both — a faceted diagonal bay under a curved glass arc, for example, with half-walls carrying the railing height where the walls stop.

The steps below condense the grid-free handling the wiki documents and the official 2019 demo shows into five moves. No mods, no cheats — this is stock build mode.
- 01
Open build mode and pick the straight wall tool
Enter build mode and select the straight wall tool from the toolbar — B is the documented shortcut for the wall tool. A straight preview line follows the cursor once the tool is active.
- 02
Decide whether this run should snap
If the diagonal must land exactly on an existing wall's endpoint, leave the grid on so the joint snaps cleanly. If you want a purely free angle, press G to switch the grid off — Toggle Grid On/Off is one of the build tools the wiki's overview lists.
- 03
Click a start anchor and drag off-axis
Click once to set the start point, then move the cursor along the angle you want and release. Walls place freely without following a set grid, so the segment runs at whatever angle you drew — a shallow 20-degree cut or a sharp 60-degree facet alike.
- 04
Chain segments for faceted shapes
Diagonal architecture rarely stops at one run: start the next segment on the previous one's endpoint and keep going — bay-window facets, cut corners, a zigzag garden wall. Leave snapping on when joints must stay precise — a room registers its floor only once its walls close.
- 05
Free-place stubborn points with Alt
If an endpoint refuses to sit where the plan needs it, hold Alt (hold) while placing and the snap lets go — the same fallback our walls guide recommends for matching off-grid prebuilt homes. Recolour the finished runs afterwards through the normal colour wheel.
Grid-free placement is documented on the wiki's Build Mode page, which cites the official Paralives (official) — Paralives - Curved Walls and Split-Level video (July 2019) — the same demo that introduced curved walls and split-level building.
What nobody has published yet
Competing guides guess at these; we would rather say the quiet part out loud. None of the following has a source we could verify as of 0.1.8b:
- How auto-generated roofs treat a diagonal footprint — whether a roof closes over off-axis walls normally, distorts, or refuses to generate. No source we found documents roofs meeting diagonals.
- How windows and doors behave on a wall drawn at a non-right angle — whether openings trim themselves to the angle or need workarounds. Nothing official or community-written describes it.
- How flooring actually responds to rotation in the current build, and what a diagonal floor would do to furniture placement and room detection. The 2022 dev chat confirms the intent; nobody has documented the shipped behaviour.
Diagonal walls FAQ
How do you make diagonal walls in Paralives?
Draw them: walls place freely without following a set grid, so pick the straight wall tool, click a start point and drag at the angle you want. Press G to stop snapping for a purely free angle, and hold Alt (hold) when a point needs free placement.
Can you make angled walls in Paralives?
Yes — angled and diagonal are two names for the same technique: straight walls draw at any angle because placement is grid-free. Draw the segment off-axis from a snapped start point, or turn the grid off first if the whole run is freeform.
What about slanted or sloped walls?
Those searches usually mean the sloped surface under an attic roof, which is roof geometry rather than a wall drawn at an angle — our attic room guide walks the roof trick that creates that look properly. This page is about walls you deliberately draw off-axis.
Can you make diagonal flooring in Paralives?
The studio said yes in principle: in the dev chat of May 13, 2022 it answered that players will be able to rotate flooring in all directions and that diagonal flooring "shouldn't be hard". That is a 2022 plan statement — how flooring rotation behaves in the shipped build is not documented.
Can you build a wraparound porch in Paralives?
The official answer from the same May 2022 dev chat was that wraparound porches "should be doable". Today's route assembles one from deck platforms, railings and stairs — our porch tutorial keeps a wraparound variant walkthrough.
Do diagonal walls affect roof generation?
Nobody has documented it. Roofs are the usual failure point for unusual footprints, but we found no source — official or community — testing how auto-generated roofs handle off-axis walls. If a diagonal build's roof misbehaves, the roofs guide collects the fixes that exist today.
Keep building
Diagonal walls rarely stay the only off-axis thing in a build — these are the guides they most often pull in.
