# Setting Ceiling and Floor Heights

Change floor reference height

## Change floor reference height

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

* Click the floor of the space.
* Please change the floor reference height in \[Space Details] on the right.\
  The floor height is set to 0 by default, and you can set level differences by room unit.\
  The floor reference height can be adjusted with +/- , and you can lower the floor surface below the reference by creating a level difference in spaces like bathrooms or entryways.
* Even if you change the floor reference, furniture positions will not change automatically.\
  You need to 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 \[Group Details] on the right.

{% hint style="info" %}
Since 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 level difference within the same space, you need to use the \[Architecture/Materials Editor] feature or a separate modeling product.
{% endhint %}

## Change room height

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

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

## Other functions

### Match space height

If you uncheck and then recheck \[Match space height], the wall heights of the room will be automatically aligned.\
This function is used to bulk adjust wall heights 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 \[Space Details] on the right, check the \[Hide ceiling] checkbox.

## Frequently Asked Questions

#### The ceiling appears open.

Did you lower the wall height below the ceiling by any chance?\
When you lower the wall height to create an effect like a half wall, the corresponding ceiling surface will appear open.\
If you are drawing a wall lower than the ceiling, use 'Draw Rectangle Column' instead of 'Draw Wall'.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
