How to Do Site Analysis in Architecture: 7 Steps

A practical seven-step workflow for studying a building site, interpreting the surrounding context and making clear architectural diagrams.

Site analysis that informs the design

Architectural site analysis is the process of learning how a place works before proposing a design. It connects the site boundary, its neighbourhood, movement, landscape, climate and constraints to a specific architectural brief. This guide shows what to research, what to draw and how to avoid confusing a beautiful graphic with reliable evidence.

Step 1 of 7

Locate the site and define the study area

The project boundary and map extent determine what the other diagrams mean.

Record the address, surrounding streets, project boundary and a useful context radius. Confirm the location against a reliable source before analysing it.

Output: Site location and context map

Site context architectural map showing the selected site within roads, buildings, water and green spaces — **Site context**
Buildings, streets, landscape, waterways and the selected project site in one map.

Step 2 of 7

Understand built form and land use

Urban grain and nearby uses affect access, privacy, programme and public-space relationships.

Compare building footprints, figure-ground and building-use diagrams. Note where classifications are unknown or incomplete.

Output: Figure-ground and building-use diagrams

Building use map with coloured categories for residential commercial and other mapped uses — **Building use**
Mapped building functions with a clear colour-coded legend.

Step 3 of 7

Map streets, access and circulation

Approach routes, public transit and street hierarchy shape how people reach the proposal.

Study transport networks and pedestrian routes where mapped. Distinguish actual direction/route data from assumptions about traffic levels.

Output: Mobility and street-network diagram

Step 4 of 7

Read landscape, water and terrain

Green infrastructure, waterfront edges and level changes influence site strategy.

Identify vegetation, water bodies and contour information. Confirm elevations with an authoritative DEM or survey for technical use.

Output: Landscape and topographic context

Site analysis relief map with terrain contour lines and surrounding buildings — **Buildings & relief**
Terrain contours, building footprints and the site context.

Step 5 of 7

Evaluate sunlight and shadow

Selected sun and shadow conditions help frame questions about outdoor space and neighbouring massing.

Compare relevant hours and contrasting seasons. State dates, geometry assumptions and limitations; do not imply a few frames equal annual daylight performance.

Output: Sun exposure and shadow studies

Summer site sun exposure map with yellow orange and blue sunlight areas — **Summer sun exposure**
Illustrative sun-exposure patterns for a summer reference period.

Step 6 of 7

Explore wind and noise context

Environmental exposure can inform where later specialist testing is most important.

Review regional wind directions, relative wind exposure and noise-context diagrams. Treat them as preliminary indicators rather than certified local wind speeds or measured dB.

Output: Wind and noise site diagrams

Colourful relative wind exposure map using turquoise yellow and coral colours — **Relative wind exposure**
Compare mapped zones of lower and higher relative exposure.

Step 7 of 7

Assemble the analysis into a design argument

A board should lead to insights, not just collect attractive maps.

Select the three to six strongest views, keep their framing consistent, write a one-sentence conclusion for each and verify important source attributions before exporting.

Output: Site-analysis sheet for concept review

Built and landscape architecture map with parkland streets buildings and waterways — **Built & landscape**
The relationship between urban fabric, vegetation and open space.

Diagram examples for the seven-step workflow

Actual outputs from Archshaper illustrate the kinds of maps that can support each research stage.

Figure ground architecture diagram with black building footprints and white open space — **Figure / ground**
A simplified map of built mass and open space around the project site.

Relative noise exposure architectural map with warm coloured intensity regions — **Relative noise exposure**
A relative visual comparison of exposure across the area.

Which site analysis diagrams do architects need?

There is no universally correct checklist. A compact urban infill study may focus on neighbouring built form, movement, daylight and overlooking. A landscape project may prioritise vegetation, water, relief and local access.

Think in terms of questions: What is already there? How do people move? What environmental conditions matter? Which legal or physical limitations need authoritative verification? Each map should answer at least one.

Primary research and desktop site analysis

A desktop workflow can help you prepare site context quickly, but it cannot replace visiting the site. Record material conditions, actual levels, acoustic character, user behaviour and any temporary factors that mapped datasets may miss.

Combine site photographs, planning information, historic research and discussions with stakeholders when those sources matter to your brief. Label each diagram with its data source and avoid implying a GIS map is a surveyed drawing.

Present findings, not just graphics

Organise the board so the reader understands where the project is, what the main conditions are and how those conditions might influence design decisions. Use concise captions with clear evidence and carefully separated assumptions.

Archshaper can reduce the drafting work behind several diagram types. The architectural judgement—selecting studies, interpreting the data and communicating decisions—remains with the designer.

Frequently asked questions

What is site analysis in architecture?

It is the study of physical, social, environmental and regulatory conditions that can influence a proposed architecture project.

What should I include in a site analysis sheet?

Usually a site-location map, urban context, circulation, built and natural systems, and the most relevant environmental conditions, plus sources and concise design conclusions.

Can I do site analysis online?

You can begin with online location and map datasets and use Archshaper to generate diagrams, but still confirm important planning, survey and performance data.

How do I start a site analysis with no GIS experience?

Choose the project location, review the available categories and begin with a site context map before selecting more specific studies.

Is one sun or wind image enough for technical design?

No. A few graphical studies do not replace time-based daylight calculations, validated CFD or specialist acoustic assessments.
