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, construction drawings with working plans etc.
I can help you with addition of toilette in your existing plans. I work on Autocad for drafting of plans. I will give you final DWG and the PDF for the updated drawing.
Warm Regards
