The retaining wall should be continuous to the foundations behind the steps, particularly if it's all that is protecting the house. 99 times out of 100 this will be the case and fire escape stairs to replace the current horrors would be an excellent idea. Somewhere I have a picture of some where I created a seating area by decking between them and a garden wall, protecting a storage area beneath.
*not all builders are created equal, get someone to have a look.
