If I understand your question correctly, you want to have some logic that can output code when the parent page is for instance ‘ProjectsPage’?

<body>
<% if $Parent.ClassName.ShortName == 'ProjectsPage' %>
	<div class="hasParentOverviewPage">
        <div>$SomeOtherLayout</div>
		$Layout
	</div>
<% else %>
	<div class="inner typography line">
		$Layout
	</div>
<% end_if %>

</body>
