I need a professional architectural design using the attached outline as a guide

I have attached 2 drawings explained below. What I have in the attached is a mess that looks like an ugly school building and I need help and inspiration. I am after a beautified" sketch at this stage of the front elevation including a garden wall " that I can take to my existing architect as an example of what good looks like.

I am keen to make the front elevation work and all be in a similar style, I am constrained by the single story extensions being flat roofs but I could put in a parapet. I will also be adding a wall with gates to the front elevation,

-P203 - This drawing is the ugly mess I speak about about
-P301 - This drawing shows some example walls.

Hopefully someone can help me.
