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.

In town and in country there must be landscapes where we can walk in safety, pick fruit, cycle, work, sleep, swim, listen to the birds, bask in the sun, run through the trees and laze beside cool waters.

The tragedy of feminine design is that it receives so little official support. Most of the world's design schools, having been organized by men, encourage a masculine approach, even when they are run by women. Yet many designers who are male in the biological sense have a feminine approach to design.

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.

Having lasted for 4,000 years, the use of nature's materials to express ideas about nature may be expected to continue. The best garden designs are produced with an awareness of the art, science, history, geography, philosophy, social habits and construction techniques of their period.

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

Planners and designers should encourage as much diversity in human habitats as they find in animal habitats. It is not possible to resolve all conflicts or to gain all ends. Choices have to be made. Different aspects of the public good should be stressed in different places. To achieve variety in land use patterns, there should also be a variety of relationships between the professions, not an institutionalized decision-making tree. Relationships between the constructive professions should, therefore, be deconstructed.
