3D perspective images are created to help a client to visualise the impact of a new design and planting in context, and at eye level, in a way that a bird's eye view masterplan cannot achieve. They can be particularly useful in showing the impact of screening trees or planting when the objective is block out neighbouring windows or structures. Visuals can be entire 3D CAD models of a house and garden or simply CAD visuals overlaid onto a photograph of a particular view.
