How to delete Widget Areas in Wordpress

Question

I am using WordPress to create a site for an estate agency. I would like to have a minimal homepage, with a text area and a background image. In the theme I am using (Agent Press) every page has 2 widget areas that I would like to delete. Is there a way to do it? I don't mind using any plugin or modifying code too. Thank you for your time and consideration.

Edit: this is my sidebar.php in the "father" theme called Genesis, where should I put the code you suggested me? (I don't know if it is right to edit this file)

<?php
/**
* Genesis Framework.
*
* WARNING: This file is part of the core Genesis Framework. DO NOT edit this 
file under any circumstances.
 * Please do all modifications in the form of a child theme.
 *
 * @package Genesis\Templates

 * @link    http://my.studiopress.com/themes/genesis/
 */

//* Output primary sidebar structure
genesis_markup( array(
'html5'   => '<aside %s>' . genesis_sidebar_title( 'sidebar' ),
'xhtml'   => '<div id="sidebar" class="sidebar widget-area">',
'context' => 'sidebar-primary',
) );

do_action( 'genesis_before_sidebar_widget_area' );
do_action( 'genesis_sidebar' );
do_action( 'genesis_after_sidebar_widget_area' );

genesis_markup( array(
    'html5' => '</aside>', //* end .sidebar-primary
    'xhtml' => '</div>', //* end #sidebar
) );

Edit: Here you are the screenshot of the pages you want to know about, tell me which you want to know more about.

Edit: front-page.php

<?php

    return;

Answer 1

You need to set an if statement on your sidebar code. use the is_page() function of wordpress:

if( ! is_page('home') ){  // Remove the sidebar on home page

   dynamic_sidebar('your-sidebar-id');

}

You can also set your sidebar on a specific page via ID or slug.

if( is_page( 123 ) ){  // via ID

   dynamic_sidebar('your-sidebar-id-1');  // Sidebar 1

}elseif( is_page('contact-us') ){  // via slug

   dynamic_sidebar('your-sidebar-id-2');  // Sidebar 2

}

Edited:

1. Navigate to Appearance > Editor on the left in the Wordpress Dashboard.
2. On the Edit Themes page, select the sidbar.php page on the right hand side in the Templates section.
3. The code for the sidebar.php will load in the Theme editor window.
4. Add a comment to the code like in the snapshot to the right. HTML comments look like the following:

<!-- Begin Comment

Code goes in between here

End Comment -->

Add the comment code to the page in the Theme editor and Click Update File
