# Define a room

Click inside a closed wall loop and Synaps creates a filled room with a centred, auto-numbered label and a live area.

**Before you start:** create a closed wall loop. A rectangle alone is not a room boundary made of walls. See [Draw a wall](/drafting/draw-a-wall.md).

## Steps

1. Open command search with **Cmd/Ctrl+K**, find **Room**, and choose the tool.
2. Move the pointer over an area that is fully closed by walls. The enclosed region fills with a live preview as you hover.
3. Click inside that closed region to create the room.

Define a room inside a closed wall boundary.

## What you'll see

A filled region appears with a centred room name and area, such as **Room 01** and **25.3 m²**. Each new room receives the next number.

## Rename a room

Double-click the room's label to edit the name. To hide the label without deleting the room, turn off **Label visible** in its controls. If a hidden label makes the room difficult to select on the canvas, select its row in **Layers**.

## Tips

* A room is detected, not drawn point by point. Your click has to land inside an area that walls fully enclose — a click outside any closed wall loop is ignored, and nothing is created.
* A room stays tied to its walls. Move or edit the walls and the room reshapes and re-measures itself.

## Properties

A room is styled through its own controls, not the shared Appearance panel. Select the room to inspect its label typography controls, including font, style, size, spacing, colour, alignment and **Label visible**. The floor fill and the room's outline are set from the room's own style controls.
