Hi, Myself Pragya.
I have seen the pictures of house that you have provided. I see how you want the retaining wall in front of the house on hilly lawn. I can certainly help in designing the retaining wall.
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, 3DS Max and Solidworks.
I provide all sorts of architectural services, e.g. 2D Site plan, 2D CAD floor plans, elevation, sections, accurate 3D model of the space along with 3D rendering etc.
Please check my profile to see my work and reviews from awesome clients that I have worked with.
