Modify AI-Generated Floor Plan for City Construction Permit

I have an AI-generated floor plan for a 1500-square-foot house that needs modifications and preparation for a building city permit. The current layout requires:

- Rearranging room layouts to improve flow and functionality.
- Changing the chimney placement to a corner of the house with a grey and white stone design.
- Adding dark grey carpet in the living room, bedroom, and hallway areas.
- Updating the kitchen flooring with grey and white marble tiles.
- Including a hallway addition with a closet at the end of the hall.

Additionally, I need assistance with:
- Preparing a material list for construction.
- Providing accurate total square footage details for the final plan.
- Estimating construction costs while ensuring compliance with city regulations.

If you have experience with residential design modifications and navigating city permit requirements, I’d love to hear about your previous projects!
