Site Analysis
Site analysis is an important part of the design process and should be undertaken at the outset of a project to inform the design principles. Development proposals need to illustrate that design decisions are based on careful analysis of the site conditions and relationship to the surrounding context.
By describing the physical elements of the locality and the conditions impacting on the site, opportunities and constraints for future apartment development can be identified and addressed in the design. It may be beneficial to undertake a site analysis in collaboration with technical consultants, depending on the nature of the site and scale of development.
The key elements of a site analysis include:
1. Site location plan
A plan showing the wider context that identifies the site in relation to retail and commercial areas, community facilities and transport.
2. Aerial photograph
A colour aerial photograph of the development site and surrounding context.
3. Local context plan
Plan drawing(s) of the existing features of the local context including relevant sections and elevations should also be provided, especially for sloping sites. Information may include but is not limited to:
• land use, height and typology of adjacent and opposite buildings in the street
• views to and from the site
• circulation patterns and access for pedestrians, vehicles and servicing
• location of heritage items and areas of environmental
significance
• patterns of buildings, open spaces and vegetation
• significant noise sources on and near the site, particularly
roads, rail, aircraft and industrial noise
• building envelopes and setbacks for future development
• a written statement of key issues.
4. Site context and survey plan
Plan and section drawings of existing site features including properties that are adjoining and on the other side of the street, together with appropriate written material. Information may include but is not limited to:
• site dimensions, site areas and north point
• topography showing spot levels and contours at 0.5m intervals, any unique natural features such as rock outcrops or watercourses and clearly identify adjoining streets and land adjoining the site
• location of major trees on site and adjacent properties
including identification of canopy size and species
• location and use of any existing buildings or built features on the site
• location and important characteristics of adjacent public,
communal and private open spaces
• location and height of existing windows, balconies, walls and fences on adjacent properties, as well as parapet and ridge lines
• pedestrian and vehicular access points
• location of utility services including electricity poles, substation kiosks, stormwater drainage, natural drainage, kerb crossings and easements.
Analysis of solar and wind access
Site analysis illustrates that design decisions have been based on opportunities and constraints of the site conditions and their relationship to the surrounding context.
5. Streetscape elevations and sections
Photographs and drawings of nearby existing buildings help explain the existing scale of the area, the spacing of development and the local architectural character. Information may include but is not limited to:
• streetscape showing both sides of any street that the development fronts including the patterns of building frontages, street and side setbacks
• adjacent buildings showing overall height (in metres and storeys) and important parapet and datum lines, awnings, colonnades and other building elements
• planned heights or building envelopes
• a written statement of key issues.
6. Analysis
These plans and sections synthesise and interpret the context, streetscape and site documentation into opportunities and constraints that generate design parameters. Analysis information may include:
• overshadowing of the site and adjoining properties by neighbouring structures. The winter sun path should be shown from 9 am to 3 pm on 21 June
• direction of prevailing wind
• geotechnical characteristics of the site including topography, and how this relates to the proposed development
• public domain interface and street setback
• relationship to and interface with adjacent properties, including side and rear setbacks
• orientation including solar access and ventilation
• building footprint location
• retained trees and tree protection zones
• proposed trees and deep soil zones
• communal open space location
• building entries
• car park footprint and depth.

Streetscape elevation
A written statement explaining how the design of the proposed development has responded to the site analysis must accompany the development application. Where relevant, this should include technical advice from landscape architects, contamination specialists, geotechnical engineers and arborists.
