Floor Plan Design

I have a church project that requires basic architectural plans and visualisation to support funding for construction. The existing layout is only a rough sketch, so I need an architect to refine and develop it into more professional floor plans, improving the design and overall functionality. The scope would include: Development of detailed floor plans based on the existing concept sketch A refined design incorporating architectural input and creative input where needed A front elevation rendering to help present the proposed building visually The building is a three-storey structure and is attached to an existing older hall, so integration with the existing structure will need to be considered. We suggest the front elevation as shown in the attached image, although it does not need to exactly match the reference.
