Hello Mr. Peter,
My name is Arturo and I am an architect designer with extensive professional experience. In my profile you will be able to see some examples of houses that I have made, both in design and rendering.
The projects that I have been able to do, so far have been for an architect in the area to review and sign them in order to process the necessary permits. I would send you the CAD files at the end so that a professional you trust can make the necessary minor adjustments requested by the state of Georgia.
I could see from the drawings you uploaded the initial idea you have. I understand that you want to have a second floor, or would it be mezzanine type?
I would start by making the 3D model in Revit, design the different environments, constantly send you 3d images to get your feedback and be part of the design process. Once the design is to your complete liking, I would export the file to AutoCad to complete the 2d drawings with all the necessary technical requirements. Also, as a gift, I would make some quality renderings for you to show to family or investors.
Just write me by chat so we can discuss the details of the project, such as: design style, needed rooms, sanitary, number of bedrooms, open concept....
Sincerely, Arturo S., architect
