The design of outdoor space can have many objectives. For garden and landscape design, the traditional summary is that a good outdoor space should be designed for:
The place should be comfortable, convenient, useful and functional.
The place should have structural stability, sound construction, sustainable technology, and good use of materials based on a knowledge of their ecological suitability.
The place should be beautiful, sublime, picturesque, inspiring, exciting, dramatic, calm, spiritual - or a selection from these properties.
The words Commodity, Firmness and Delight are translations, by Wotton, from the Roman author Vitruvius Pollio.
