# 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 space floor.
* In the right \[Space Details], 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 +/-; you can create a level difference in spaces like bathrooms or entryways to lower the floor surface below the reference.
* Even if you change the floor reference, furniture positions are not changed automatically.\
  You need to manually adjust the \[Height from Floor] of the furniture items, and if you want to change them in bulk, use multi-select Shift+drag or, when grouped, modify \[Height from Floor] in the right \[Group Details].

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

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 level difference within the same space, you need to use the \[Architecture/Material Editor] feature or a separate modeling product.
{% endhint %}

## Change room height

To adjust a room's ceiling height, click the room floor, then adjust the room height in the right \[Space Details].\
The wall length and ceiling position will change together by room.

* If you want to change the ceiling height of the entire floor, not by room, go to the left tab \[Floor Management] → \[Floor Height] and change it in bulk. ([Manage floors](/guide/user-guide/make-project/floor-management.md))

## Other Functions

### Match space height

If you uncheck and then check \[Match space height], the room's wall height will be automatically matched.\
If the wall height in a room is not uniform, this feature adjusts the wall height in bulk based on the ceiling height (room height).

### 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 the effect of a half wall, the ceiling surface will appear open.\
If you are drawing a wall lower than the ceiling, use 'Draw rectangular column' 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-guide/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.
