That is quite simple, you need to use PresentationContext service. Here is an example:

ServiceLocator.ServiceProvider.GetService<IPresentationContext>().GetDesignItem(CONTEXT_ITEM);

It will do all the work your you:

1. check if there is design selected on your page
2. check design rules
3. and at the end check Template to Design Mapping field (if design won't be resolved from above ones)

You can also inject PresentationContext using constructor injection like this:

public class MyClass
{
    protected readonly IPresentationContext PresentationContext;

    public MyClass(IPresentationContext presentationContext)
    {
        PresentationContext = presentationContext;
    }
}
