How should I best design the approach to the front entrance?! Stairs, path or extension.

What do you mean by that? Which extension? Which stairs, which path? And how is your drawing to be understood -> balcony/terrace? Do you have a slope? Then please write how steep, from where to where... and where is the property located? Why two stairs on the ground floor? A lot of information is missing!
If it is even remotely as I understand it, the staircase going down will suffer from chronic lack of space - unless it leads directly outside (i.e., beyond the edge of the house). It will be tight in any case.
