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 have seen the image you have attached for roof top bar. I can help you in 3D modeling and exterior design and rendering of the building if you can please share the source sketchup file.
Please refer to my portfolio for some of my work.
Warm Regards
