Hi myself Pragya.
I have been working as professional architect and interior designer for last 5 years.
I am quite handy with Autocad, 3D modelling software like, Sketch up , Revit, Lumion, Sketchup, 3DS Max and Solidworks.
I provide all sorts of architectural services, e.g. Site planning, elevation, sections, accurate 3D model of the space along with 3D rendering etc.
I will help you with 3D modeling of the whole apartment and one flat interior, and as outcome, I will provide you full HD video walk through of exterior as well as interior like you have asked in project description.
Please refer to my portfolio for some of my work.
Warm Regards
