# Set Ceiling and Floor Height

## Change floor reference height

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

* Click the floor of the space.
* In the right \[Space Details], please 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 lower the floor surface below the reference by creating a step in spaces such as bathrooms or entryways.
* Changing the floor reference does not automatically change furniture positions.\
  You must manually adjust each piece's \[Height from Floor], and to change them in bulk, please use multi-select with Shift+drag or, when grouped, edit \[Height from Floor] in the right \[Group Details].

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

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

If you want to create a stepped effect within the same space, you'll 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 room's floor, then adjust the room height in the right \[Space Details].\
The wall length and ceiling position will also change together by room.

* If you want to change the ceiling height of 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

If you uncheck \[Match space height] and then check it again, the wall height of the room will be adjusted automatically.\
This feature adjusts wall height in bulk based on the ceiling height (room height) when the wall heights in a room 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 \[Hide ceiling] checkbox.

* Click the floor or ceiling surface.
* In the right \[Space Details], 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 an effect like a half wall, the corresponding ceiling surface will appear open.\
When drawing a wall lower than the ceiling, please use 'Draw Rectangular Column' instead of 'Draw Wall'.

## 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.
