# Set Ceiling and Floor Heights

## Change floor reference height

If you want to create level differences by space, you can change the floor reference height.

* Click the space floor.
* In the \[Space Details] panel on the right, change the floor reference height.\
  The floor height is set to 0 by default, and you can set level differences by room.\
  The floor reference height can be adjusted with +/- , and you can create a step-down in spaces like bathrooms or entryways to lower the floor surface below the reference.
* Changing the floor reference does not automatically change furniture positions.\
  You must manually adjust the \[Height from Floor] of the furniture, and to change them in bulk, use multi-select Shift+drag or, when grouped, modify \[Height from Floor] in the right-side \[Group Details].

{% hint style="info" %}
Because floor height can only be adjusted by space,

if the entryway is connected to the living room without a partition door, it is difficult to lower only the entryway floor separately.

If you want to create a stepped effect within the same space, you need to use the \[Architecture/Material Editor] feature or separate modeling products.
{% endhint %}

## Change room height

To adjust the ceiling height of a room, click the floor of the room, then adjust the room height in \[Space Details] on the right.\
The wall length and ceiling position will change together at the room level.

* If you want to change the ceiling height for the entire floor plan rather than by room, go to the left tab \[Floor Management] → \[Floor Height] and change it in bulk. ([Manage floors](/guide/user-en/make-project/floor-management.md))

## Other Features

### Match space height

After unchecking \[Match Space Height] and checking it again, the wall height of the room will be automatically matched.\
This feature is used to adjust wall heights in bulk based on the ceiling height (room height) when the room wall heights are not uniform.

### Hide ceiling

If you want to create a space without a ceiling, such as a terrace or outdoor area, turn off the checkbox for \[Hide Ceiling].

* Click the floor or ceiling surface.
* In \[Space Details] on the right, check the \[Hide Ceiling] checkbox.

## Frequently Asked Questions

#### The ceiling looks open.

Did you perhaps lower the wall height below the ceiling?\
If you lower the wall height to create the effect of a half wall, that ceiling surface will appear open.\
When drawing a wall shorter than the ceiling, use 'Draw rectangular pillar' instead of 'Draw wall' to place it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.archisketch.com/guide/user-en/make-project/ceiling-floor-height.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
