Site analysis is assessing the site and drawing inferences to aid further design conception and implementation.

Why there is a need of Site Analysis?

  • The assessment provides the relevant information regarding the environment, natural and artificial features of the site.
  • This ought to be used as starting process for the design process.

Site analysis aids in the following ways :

  • Avoiding inappropriate design responses
  • Legal Applications
  • Discovering interrelationships
  • Greater efficiency when designing factors


  • Location
  • Neighborhood context
  • Climate
  • Site


Why there is need to look for location?

  • To understand the relation of site with region and their influence on it.

What is Neighbourhood context?

  • Immediate surrounding and it may include important factor around the site in its proximity.

Why there is a need to look at Neighbourhood context?

  • To identify and analyse the various factors in the vicinity that could affect the site’s built environment.
  • Immediate context
  • Circulation
  • Sensory

a. Immediate context

What is Immediate context?

  • It refers to all activities which are taking place around the site w.r.t allocation and development.

Why there is a need to look at Immediate context?

  • To understand the influence of surrounding zoning on site w.r.t users and activities.

b. Site and Surrounding Circulation

What is site and surrounding circulation?

  • Traffic generators


  • Pathways
  • Footpaths

Road networks

  • Widths
  • Major, minor streets


What is sensory perception?

  • Observation of audio visual stimuli to and from the site and to take its advantage.

Why there is a need to look at sensory aspect of site?

  • To judge the relative desirability of sensory conditions on site.
Factors of sensory:
  • Visual/Views
  • Noise
  • Odour

How to study Neighbourhood Context?

  • It is hereby explained through a residential site example:


What is climate?

  • Mean weather conditions over a period of time

Why there is need to look for climate?

  • To harness prevailing climatic conditions for creating comfort conditions
  • Protect space and building from prevailing winds, cold and from down pour- rain and snow
  • Efficient daylight into space and building
  • Shade and exposure to sunlight via openings
  • Durability and optimum usage of materials

Components of Location:

  • Macro Climate
  • Micro Climate
Macro Climate

What is macro climate?

  • Overall climate of the region.
Factors which affect macro climate:
  • Temperature
  • Relative humidity
  • Wind direction
  • Rainfall
Micro Climate

What is micro climate?

  • Immediate local climatic conditions
Factors which affect micro climate:
  • Topography
  • Water bodies
  • Vegetation
  • Construction materials

Note: A Special features like water bodies, green and open spaces near the site affect the microclimate, So allocation of activities on the site should be done accordingly

How to study climate?

  • Macro Climate: Climatic information such as rainfall, snowfall, wind directions, temperatures, sun path, all assessed during the different times of the year.
  • Micro Climate: To analyse the micro climate according to the occupancy or usage of the project

For example:

A. Residence

  • Diurnal temperature of the day should be analysed.

B. A School

  • The analysis should be done for the first quarter of the day.

4. SITE:

Why is there a need to assess the Site?

  • To analyse different aspects of site on and around it.

Components of site:

  • Size and by laws
  • Natural physical features
  • Man made features
Size and by laws

What includes in size and by laws?

  • Dimensional aspects and legal verification of site like Building by laws, Sustainable by laws, etc.

Why there is a need to study by laws?

  • To ensure the orderly development of site.
  • Sufficient ventilation and air.
  • No building blocks the lighting and ventilation of neighbors.
  • Health and comfort conditions.
Factors of Size:
  • Dimensions
  • Area
  • Shape
  • Boundaries
Factors of By laws:
  • Built up area
  • Restricted height
  • Setbacks
  • Parking
  • Allowable usage
  • FAR, BAR

How to study by laws?

  • By laws is to be studied from the local government development authority for understanding prevailing by law

Natural physical features:

What are Natural Physical Features?

  • It includes different landforms of site and its characteristics

Why is there a need to look at Natural Physical Features?

  • To analyse the placement of different activities of site w.r.t. the existing features.

Components of site:

  • Geology
  • Topography
  • Seismic zone
  • Geo-hydrology
  • Flora & Fauna


What is Geology?

  • Earth science comprising study of solid earth.

Why there is a need to look at it?

  • To assess the nature of soil and in turn the stability of land and its effect on the building.
Factors of Geology:
  • Soil type
  • Bearing capacity
  • Stability

How to study geology?

  • It can be analysed according to type of soil.

For example:

a. Coarse Grained Soils (eg. Sands and Gravel)

  • As coarse grained soils has good bearing capacity.
  • Strip foundation is recommended.

b. Fine Grained Soils (eg. Silts and Clays)

  • It has good-load bearing qualities when dry
  • Pile foundation is recommended.

  • To understand allocation of activities w.r.t topography.
Factors of Topography:
  • Contour map
  • Ridges, Valleys, Slope or flat
  • Low point and high point

How to study topography?

  • To study topography through different slope of the land.

For example:

a. Ridge

  • One must consider the locations and elevations of different activities on and around the site.

b. Valley

Seismic zone:

What is Seismic Zone?

  • Seismic zone is a region in which the rate of seismic activity remains fairly consistent

Why there is a need to look at Seismic activities?

  • Land
    • Earthquake
    • Landslides
    • Volcano
  • Water
    • Floods

  • To analyse the effects of the water table, soil porosity, seepage, soil strength and how it affects the building.

Factors of Geohydrology:

  • Groundwater level
  • Sources/Modes of water
  • Characteristics of water

  • Available vegetation like trees, crops etc and living organisms like insects , termites etc

Why there is a need to look at Flora and Fauna?

  • To understand the influence of flora and fauna on project development.

Man made features:

What are Man made Features?

  • Things that are created or caused by humans rather than occurring naturally on and around the site

Why there is a need to look at Man made Features?

  • To understand the influence of man made features for the development of the site

Factors of man made features:

  • On site Features which may present on the site.
    • Structure
    • Paving patterns

  • Off site Features which may available in the nearby surrounding area.
    • Electricity poles
    • Water lines
    • Sewer lines
    • Telephone lines
