# Objects & buildings
You can build objects and buildings inside your tiles to decorate or add new features to your kingdom. Tiles have limited space, and some buildings have to be unique per tile.
You can also buy pre-built objects directly from other players.
### Recipes
To build objects or buildings inside your tile, you need recipes; a recipe gives you the list of resources and items you need and the guidelines.
Some recipes are available in limited editions, so only the plan’s owners can build and sell these objects or buildings.
Players can collect and trade recipes; if you own all the recipes of a limited edition, you will become the only player able to build these objects or buildings.

## 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.kingdom.so/guide/objects-and-buildings.md?ask=&goal=
```
`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.
