Hi, I'm Ar. Harsh Kataria and I have read the description of your project regarding Add stairs and bathroom to existing floor plan
I am an experienced architect and interior designer, I work in Revit and I can meet all your requirements in Revit and provide you with CAD drawings. I have also worked on similar project before also. I can provide you 3D drawings, plans, elevations and other requirements. I can probably submit it to you soon.
So you can trust me and do your job. I will be waiting for your revert.
Thanks and regards
Ar. Harsh
