Urban design principles for parks, street spaces, plazas and communal open spaces.
Public spaces are those areas in the public realm that provide a public use or recreation function, such as parks, plazas and street spaces.
Public spaces are generally located on publicly held land, are accessible to everyone and are managed and maintained by councils or other public agencies. Some privately held land provides for controlled public access and use as a public space, such as a building forecourt, a walk-through, a shopping mall or a communal open space. Public spaces are created as part of a land subdivision or by reallocation of land uses in existing urban areas.
Public spaces accommodate a diversity of activities, and provide interest and amenity for people. Critical factors for successful public spaces are their location, size, dimensions and the interfaces with adjacent properties, the paths and arrangement of activities within the space. The area surrounding public spaces also influences how they are used and perceived. A functional system of public spaces offers direct connections to the surrounding pedestrian network and includes through-paths.
Public spaces are essential for the wellbeing of everyone in a community. They provide opportunity for relaxation, recreation and socialising, and contribute to a neighbourhood's local character and sense of place. Active, safe and enjoyable public spaces draw people to them.
More than a third of the urban land area is public space, mostly streets. Green spaces such as parks make up the second largest component of public space. Street spaces, plazas, forecourts and squares provide for regular and chance social encounters. Parks and green spaces provide opportunities to relax, participate in active recreation and experience nature. Semi-public and communal open spaces, such as courtyards in apartment buildings, hospitals and education facilities, provide for casual interaction and recreation
Edges are often the most populated parts of public spaces. People tend to gravitate to, and occupy, the edges of places because they provide good vantage points to view activities within the space as well as to the surrounding area.
3.1 Public spaces principles
A number of agencies are responsible for managing public spaces. Any one public space may have multiple agencies and organisations with different responsibilities, leading to complexity in coordination of development and management.
Highly accessible public spaces that are extensions of the street system.
Street spaces are that part of the street used for social purposes, such as a widened footpath or a pedestrian-only mall. Plazas range from a building forecourt to a large city square. A plaza is often bordered by buildings or streets.
Most street spaces and plazas are paved, and can include trees and other planting, but they are distinguished from parks. The spaces may have vehicles running adjacent to the pedestrian zone, be a shared zone, or may be free of vehicles. Some street spaces operate for specific periods of the day or week to accommodate different use patterns. While street spaces are generally publicly owned and managed, plazas may be publicly or privately owned but still open to the public at all hours.
Streets are the predominant and most frequently used public spaces in any city. Street spaces and plazas link with the movement network, allowing people to use them as through routes as well as places to linger and socialise. They usually have places for people to sit, eat their lunch, find some sun or shade, get out of the cold wind or rain, chat with friends or watch their children play. They also provide opportunities for people to observe the world around them.
Element 2.2 Pedestrian priority streets
A street space or plaza performs well when bordered by pedestrian priority streets and buildings with a high level of activity that open on to the space.
Green public spaces up to one hectare in size that include grass, gardens and playgrounds.
Local parks are green public spaces up to one hectare in size and may include trees, grass, gardens and playgrounds. Some local parks also include water features, cafes or sports facilities. The location of a park in the movement network often influences its useability. Parks must connect directly to the pedestrian network and be located within easy reach of users.
The most valued parks will be those used by a range of people for a variety of reasons throughout the day. Parks with active uses adjacent to and fronting them are usually more popular than those surrounded by fences and blank walls. Parks can also support natural systems and habitat.
Parks provide open space for relaxation, recreation and socialising. They also provide a space to be closer to nature, with relief from the noise, activity and hard surfaces of an urban environment. Parks also play an important role in enabling people to be more physically active and healthy. People prefer to use parks that are easy to reach and that feel safe and comfortable. Parks feel and become safer as more people use them. The success of parks is not just a question of scale or quantity, but where the park is located and how it is arranged.
Areas set aside on private land for shared recreation by building occupants and, in some cases, visitors.
Communal open space is an area within a private site providing for informal recreation activities for common use by building occupants and, in some cases, visitors. Communal open space is often incorporated into higher density residential developments, education facilities, supported residential facilities, health care facilities and hospitals, or commercial buildings. They can include roof terraces, courtyards, contemplation gardens, atriums, walled gardens, playgrounds, play spaces and dog gardens. Communal open space may comprise paved areas, grass, gardens, shelters and seating. Depending on the intended user, it may also include pools, garden plots and barbecues.
Access to well-designed communal open space is important for the wellbeing of building occupants, especially residents of higher density residential buildings. Communal open space provides opportunities for relaxation, socialising and to enjoy outdoors. Communal open space can also support natural systems and habitat.
Communal open spaces need to be of an adequate size and in an accessible location to enable building occupants to use them. Remote, small or uncomfortable spaces are rarely used, and may become neglected or unsafe.
