Hi. Not sure about your site, since nothing is prepared on it so that it is possible to help you.

Nevertheless, here is the approach for standard Helix. You can adapt it to your site.

Set the blog layout to one column.

Use the following CSS.

.article-list .article {
    display: flex;
    align-items: center;
    gap: 30px;
}
.article-list .article > a {
    flex: 0 0 30%;
}
.article-list .article .article-intro-image {
    margin: 0;
}

Will look like that
