Reshuffle of internal rooms layout

I am looking for a skilled professional who can help me with a reshuffle of the internal rooms layout in my space. The current layout consists of a combination of open concept and individual rooms. I am open to reshuffling the entire space, as there are no specific rooms that need to be targeted. The main purpose of the reshuffle is to achieve better functionality in the space.

Skills and Experience Required:
- Experience in interior design and space planning
- Knowledge of architectural principles and building codes
- Proficiency in using design software and tools
- Ability to suggest and implement creative solutions for better functionality
