tmuxp.workspace.builder.ClassicWorkspaceBuilder.build(self, session: Session | None = None, append: bool = False) -> None
```

Build tmux workspace in session.

Optionally accepts ``session`` to build with only session object.

Without ``session``, it will use :class:`libtmux.Server` at ``self.server``
passed in on initialization to create a new Session object.

## Parameters

- `self`
- `session` (Session | None): session to build workspace in
- `append` (bool): append windows in current active session
