House Layout Redesign for Functionality

I'm seeking a skilled professional to help me improve the functionality of my home. The primary focus is the staircase area, which I would like to be relocated. Additionally, I need to enlarge my kitchen and dining room, as well as my porch.

I`m after a professional advise if my proposed changes are feasible at all. Then to produce a new floor plan that could be structurally achieved.

Ideal candidates should have:
- Extensive experience in home design and renovation
- A keen understanding of spatial functionality
- Ability to create a more practical living space without compromising on aesthetics.
