Why does my furniture automatically jump to the wall on the drawing?

It's a snap feature — a shortcut that straightens the furniture parallel to the wall and pulls it in close when you drag it nearby. It exists because most furniture ends up there anyway, but it can be turned off.

What the snap feature actually does

When you drag a piece of furniture toward a wall, the app continuously compares the furniture\'s angle to the wall\'s direction. Once the furniture comes within a certain distance — typically a few centimetres — the app automatically straightens the furniture\'s angle so it becomes exactly parallel to the wall, and pushes it in until a small, fixed air gap remains, often around 2 cm. Without the feature, you would have to reset the angle with your fingers every time, which is hard to do precisely on a small screen.

Why a small gap, and not flush against the wall

The 1-2 cm of air is deliberate. Skirting boards, radiators and unevenness in the wall mean that a piece of furniture in real life almost never sits flush against the actual wall surface — there is always a bit of air. A snap feature that placed the furniture exactly on the wall line would therefore be less realistic than one that leaves the centimetre or two that\'s usually there in practice.

Why it can feel like a bug

The typical moment of irritation is when you try to deliberately place a piece of furniture slightly away from the wall — a bookcase that needs to stand in front of a radiator, say, or a bed that needs room for a bedside-lamp cable behind the headboard. Then the feature "grabs" the furniture and pulls it all the way in, even though you wanted it to stay further out. That\'s not a bug in the app, but a sign that snap is designed for the far more common case: furniture that genuinely should stand close to the wall.

When snap is an advantage

• Sofas, wardrobes and chests of drawers — furniture that almost always stands parallel to, and close to, a wall.
• When you\'re planning quickly. You avoid having to fine-tune every single angle manually while trying out different layouts.
• When the room has crooked walls. Snap aligns the furniture to the wall\'s actual angle, not the screen\'s vertical and horizontal axes — useful in a room that isn\'t quite square.

When you\'ll want to turn it off

• Furniture angled on purpose. A reading chair turned 30 degrees into the room, a dining set set diagonally to make use of a corner.
• Furniture that needs to stand some distance from the wall. In front of a radiator, a skirting board, a socket that needs to be reachable, or just to leave room to walk behind it.
• Freestanding furniture in the middle of the room. A bookcase used as a room divider, a coffee table nowhere near a wall.

How to avoid it snapping without turning the feature off entirely

The simplest shortcut is to keep the furniture a little further from the wall than you actually want it to end up — the snap feature only reacts within a certain distance. If the furniture stays outside that distance, your own placement and angle remain untouched. If the furniture needs to sit very close to the wall but still not quite parallel, it\'s often easier to switch the feature off temporarily, place the furniture, and switch it back on afterwards.

Why furniture generally should sit close to the wall on a floor plan

Beyond the fact that this is often how furniture actually stands in real life, it also makes a furnishing plan easier to read. A room where all the large pieces are pushed up against the walls leaves a clear, continuous walking area in the middle — it\'s easier to judge whether there\'s enough room to move around when the furniture isn\'t scattered randomly across the floor. That is one of the reasons snap makes sense as the default behaviour for most cases, even though it doesn\'t suit every placement.

What if the furniture snaps to the wrong wall

In a small room with furniture close to several walls, it can happen that a piece snaps to a different wall than you intended, if it comes within range of both. The usual fix is to drag the furniture well away from both walls first, and then approach only the wall you actually want it against — that way there\'s no doubt which wall the feature reacts to.

Does snapping affect the measurements?

No — snap only changes the furniture\'s position and angle on the drawing, not the furniture\'s own width and depth. The measurements you scanned or typed in stay the same, whether the furniture is standing freely in the middle of the room or snapped to a wall. All that snap calculates is where the furniture\'s edge should sit relative to the wall\'s actual line, as known from the scan or your own drawing.

Other features that use the same logic

Snap-to-wall is related to, but not the same as, other forms of automatic alignment you might know from drawing programs — for example, two pieces of furniture aligning to each other\'s edge, or a piece of furniture centring itself in front of a window. In a floor plan, wall snap is the most common, because the vast majority of furniture in a home genuinely stands against a wall. The more a room is furnished with free, central placements — a dining table in the middle of the room, a daybed used as a room divider — the less useful the feature is, and the more often you\'ll want to turn it off along the way.

What HouseSense does

In HouseSense, the snap feature automatically straightens a piece of furniture parallel to the wall and places it with roughly 2 cm of air when you drag it close. The feature can be turned off if you want to place furniture at an angle or deliberately away from the wall. Alongside it, the app shows the distance from both ends of the furniture to the wall\'s corners in metres, so you can see exactly how much space is left on each side, even when the furniture isn\'t touching the wall.

Decision: let it snap, or turn it off

1. Is the furniture a sofa, wardrobe or something else that naturally stands against a wall? Let snap do the work.
2. Does the furniture need to stand deliberately away from the wall — radiator, cable, skirting board? Turn snap off, or keep the furniture outside the reaction distance.
3. Is the furniture angled on purpose? Turn snap off before you settle on the final angle.
4. Does the furniture snap to the wrong wall in a tight room? Pull it well away from both walls and try again from only one side.
