What Is Site Analysis?

Site analysis is a vital part of architecture, involving examining and evaluating aspects of a location. The primary objective is to collect relevant information and transform it into diagrams to make informed design choices. Considering project attributes is crucial to achieving success. Site analysis diagrams visually represent observations, showing patterns of sunlight, movement, land use, and spaces.

What Is The Purpose Of A Site Analysis?

Site analysis is crucial for designers to understand a project site. They examine aspects like location, size, topography, zoning, traffic, climate, and potential changes. Site analysis diagrams provide architects with data on sun and shade patterns, movement, land use, and public/private spaces. This helps designers create a design that integrates with external conditions. Site analysis benefits both designers and clients by ensuring financial feasibility.

How To Do Site Analysis?

Obtaining a high level of detail is crucial for a comprehensive site analysis. Designers need to consider the contextual aspects of the building or structure they are creating. It is important to understand how the construction will fit in with the surrounding space and how the space itself will impact the construction process. These factors are critical in conducting a thorough site analysis. To ensure an informed architectural site analysis, it is necessary to follow these three steps before starting construction.

1. Research

When analyzing a site, look beyond property boundaries. Research the site’s physical condition and history. Use online tools to access relevant information and visit the site in person. Take notes, pictures, and measurements to assess size, parking, accessibility, public transportation, and noise level. Gathering comprehensive information is key for a thorough analysis.

2. Analysis

After a site visit, analyze findings by reviewing and comparing information, using visual aids like diagrams. Consider project goals and site characteristics.

3. Synthesis

The information you gather and conclusions you reach during site analysis will provide context for your project. Data collection is important, but it must be transcribed into relevant content. Analysis will reveal which site conditions influence design parameters. Combine your research, observations, and limitations to begin schematic design and programming.

Site Analysis Checklist Of Data Types

Conducting thorough research and performing a comprehensive site analysis is of utmost importance. Inadequate site analysis may result in costly or difficult problems that could be hard to address during later stages of the design or construction process. During a site analysis, there are three types of data that should be collected and analyzed. We will discuss each of these data types separately. The best analysis considers all three. These include:

Mega , Macro, Micro

When conducting a site analysis, it is important to take a strategic approach that involves examining both objective and subjective data across three distinct scales.

Mega scale encompasses the broader context of the site, including the suburb and its relationships within the larger city.

Macro It refers to its large-scale context, including surroundings on all sides.

Micro It examines the minutiae, qualities, and characteristics of individual elements and objects.

The site and project cannot be considered independently, as they are part of an existing and constantly evolving. They are interdependent with and have connections to the immediate surroundings, the broader site, the suburb and city, as well as the local community and its residents.

Objective Or Hard Data

Objective or hard data refers to the physical characteristics of a site, independent of human interaction. This type of data is considered objective because it exists regardless of our observations or experiences. Objective data may include the following:

01 | Location

Geographic Location: Determine the precise location of the site, including the address, lot number, or any other relevant reference.
Site Survey: Acquire the site survey document and extract meaningful information, such as measurements and other significant details.
Aerial Photographs And Maps: Gather historical and up-to-date aerial photographs and maps of the site, suburb, and surrounding areas. Analyze these documents to identify noteworthy information related to the site.
Site Boundary: Locate and verify the site’s boundaries, ensuring they are clearly defined and accurate on the physical location.
Dimensions: Ascertain the size, measurements, angles, shape, and proportions (including radii) of the site.

2 | Authorities

refer to the regulations, limitations, and permissions set by federal, state, and local government bodies. It’s crucial to identify both the level of government and the specific departments responsible for overseeing development in the area under consideration.

Overlay Obtain the overlay plans to identify any additional overlays, such as heritage, environmental, conservation, or green belt designations that may impact the site. Understand the allowances and restrictions for development and construction within these overlays.

Flood Levels Gather flood records to determine frequency of regular floods, such as 50- or 100-year floods. Note required building elevations above specified water levels.

3 | Adjacent Structures And Conditions

Distance To ensure proper spatial planning, it is important to calculate the distances between the site and its neighboring sites, spaces, and structures.
Heights It is important to evaluate the various heights of the adjacent sites, spaces, and structures.
Vernacular Consider the vernacular, styles, and distinct features of neighboring sites and structures.

4 | Streetscapes, Elevations And Sections

5 | The Natural Physical Conditions And Features

refer to the inherent elements and characteristics of the site.

Typography Acquire existing surveys to verify accuracy of natural and man-made contours, levels, gradients, slopes, and terrain.

Vegetation It is important to identify and note the different types of vegetation on the site. Pay attention to their heights, canopy widths, and root coverage.

Geology, Soil Type, And Condition It is important to obtain any available geotechnical or soil reports to understand the soil and rock conditions on the site. This will help determine how these conditions may affect the type of structures or construction in different areas of the site. Knowing the geology, soil type, and condition will help make informed decisions about the feasibility and design of the construction project.

Natural Qualities And Characteristics Observe the natural materials, textures, colors, and patterns in and around the site.

6 | Artificial Physical Conditions
