SketchUp Building: Exterior Modifications

I'm looking for an experienced SketchUp designer to assist with several exterior modifications to a building model.

Key responsibilities will include:
- Altering the current roof structure and shape
- Implementing some landscape changes (adding more greeneries)

Ideal candidates will have:
- A strong portfolio showcasing previous work with SketchUp, particularly with exterior modifications
- Experience with both roof modifications and landscape alterations
- A creative approach to facade redesign and roof material changes

Please include examples of relevant past projects in your proposal.
