Are My Foundations OK?

[ultramods]

The house has 8 external doors that I have highlighted yellow on the image below.

 

Can anyone please tell me why do only 3 of the areas near a door have the extra protruding block work (circled in blue)?

I presume that is for supporting an external step?

 

Is it only the main entrances that have this, and perhaps the others are expected to open onto e.g timber decking?

There will be paving all round the house level with the doorways, however this is a change from the original plan. So maybe as you say they were originally for steps.
