Landscape planners will have the opportunity to make sculptured roofscapes, so that cities appear to be verdant hills and valleys. Streets will become shady routes carved through the undergrowth. Roofs will become mountain tops. People will become ants.

From 50 centuries, we can learn about the close relationship between garden design and urban design, because both arts involve the composition of buildings with paving, landform, water, vegetation and climate.

Many of the world's best-designed cities have been inspired by garden concepts.

Modernism', as a label, has currency in the arts, architecture, planning, landscape, politics, theology, cultural history and elsewhere.

Garden design theory explains, or should explain, the 'What, Where, Why and How' of making gardens.

The strengths landscape architecture draws from its garden design heritage include: the Vitruvian design tradition of balancing utility, firmness and beauty; use of the word 'landscape' to mean 'a good place' - as the objective of the design process; a comprehensive approach to open space planning involving city parks, greenways and nature outside towns; a planning theory about the contextualisation of development projects; the principle that development plans should be adapted to their landscape context.
