Site Diagnostic

Site analysis diagram with the four domains of investigation

Every successful landscape project begins with understanding.

The quality of a landscape project is determined long before ground is broken, and long before design begins.

Before recommendations can be made, it is important to understand the site itself. Every place presents a unique combination of physical, environmental, ecological and regulatory characteristics that influence what is realistically achievable. This is a fundamental part to every Sydney landscape assessment. Investigating these conditions before important decisions are made helps establish a clear understanding of the opportunities and constraints that will shape the project.

At Jasper Green, every landscape design project begins with a Site Diagnostic.

Rather than beginning with concepts or assumptions, the Site Diagnostic provides a structured process of investigation, observation and analysis that creates the foundation for informed decision-making. It reduces uncertainty, establishes clarity and ensures that future design recommendations are based on evidence rather than assumption.

What is a Site Diagnostic?

A Site Diagnostic is a structured investigation of a place before landscape recommendations are made. It is the basis of a Sydney landscape assessment.

Its purpose is to investigate, analyse and understand the characteristics of a landscape before important decisions are made. Rather than beginning with design solutions, the Site Diagnostic establishes the knowledge needed to determine what is realistically achievable and to inform future decisions.

This process goes beyond recording measurements or documenting existing conditions. It involves observing, investigating and interpreting the site as a whole, identifying both the opportunities that can be leveraged and the constraints that must be carefully considered.

The result is a clearer understanding of the site’s potential, reduced uncertainty and a solid foundation for informed decision-making before significant investment is made.


Why investigate?

Every landscape recommendation depends on the quality of the information it is based upon.

Without understanding the opportunities and constraints of a site, important decisions are made using assumptions rather than evidence. While assumptions can sometimes lead to successful outcomes, they also increase the likelihood of unnecessary compromises, avoidable costs and missed opportunities.

Investigating a landscape before design begins establishes a clearer understanding of what is possible, what may influence the project and what factors should be carefully considered.

This provides a solid foundation for informed decision-making before significant investment is made.

The purpose of a Site Diagnostic is not to delay design. It is to ensure that design begins with a clear understanding of the landscape it is responding to.


What does a Site Diagnostic investigate?

Every Site Diagnostic investigates four key domains that influence future decision-making.

Physical

Understanding the existing characteristics of the landscape and how they may influence future opportunities.


Environmental

Investigating the natural conditions that shape how the landscape performs throughout the seasons.


Ecological

Evaluating the living systems that contribute to the health, resilience and long-term performance of the landscape.


Regulatory

Identifying the statutory and planning considerations that may influence future development.


No single characteristic determines the success of a landscape. It is the interaction between these domains that shapes both the opportunities available and the decisions that follow.

What do you receive?

The Site Diagnostic provides a documented assessment of the landscape and the factors that will influence future decision-making.

Depending on the characteristics of the landscape, a Site Diagnostic may include:

  • Site observations and measurements
  • Photography of existing conditions
  • Analysis of opportunities and constraints
  • Supporting site analysis
  • A written Site Diagnostic memorandum
  • Recommendations for appropriate next steps

Every Site Diagnostic is tailored to the landscape being investigated. While no two sites are the same, the objective remains consistent: to establish the understanding needed to support confident, informed decision-making.


From understanding to recommendations

The Site Diagnostic establishes the knowledge needed to define the project with greater confidence.

For landscape design projects, the findings from the Site Diagnostic inform the next stage of the design process. Together with the project’s objectives, they provide the foundation for developing a landscape recommendation that responds appropriately to both the landscape and the way it will be used.

Rather than starting with assumptions or predetermined solutions, every recommendation is grounded in a structured understanding of the landscape and the opportunities it presents.

Frequently Asked Questions

Why is a Site Diagnostic important before landscape design?

A Site Diagnostic establishes the understanding needed before landscape recommendations are made. By investigating the opportunities and constraints of a landscape before design begins, it reduces uncertainty and provides a solid foundation for informed decision-making. This helps ensure that future recommendations respond appropriately to the landscape, the project’s objectives and the factors that may influence the outcome.

What does a Site Diagnostic include?

Every Site Diagnostic is tailored to the landscape being investigated. Depending on the site, it may include site observations and measurements, photography, analysis of opportunities and constraints, supporting site analysis, a written Site Diagnostic report and recommendations for appropriate next steps. The focus is always on developing a thorough understanding of the landscape before important decisions are made.

How long does a Site Diagnostic take?

A Site Diagnostic includes both an on-site assessment and the professional analysis that follows. The site visit typically takes up to two hours, depending on the landscape, and is followed by supporting site analysis, evaluation and the preparation of a written Site Diagnostic report. The objective is not simply to inspect the site, but to develop the understanding needed to support confident, informed decision-making.

Do I need a Site Diagnostic before every landscape design project?

Yes. Every landscape design project undertaken by Jasper Green begins with a Site Diagnostic. It forms the foundation of the design process by establishing a clear understanding of the landscape before recommendations are developed. Beginning with investigation helps reduce uncertainty and ensures that decisions are informed by evidence rather than assumptions or preferences alone.

Can I book a Site Diagnostic on its own?

Yes. A Site Diagnostic can be commissioned as a standalone service. Some clients simply want a professional assessment of their landscape before deciding how to proceed, while others use it as the first stage of a larger landscape project. In either case, the Site Diagnostic provides valuable insight that helps reduce uncertainty and supports more confident decision-making.

What happens after the Site Diagnostic is complete?

The Site Diagnostic concludes with a documented assessment of the landscape and recommendations for appropriate next steps. Where it forms part of a broader landscape project, the findings help define the project before design begins. Together with the project’s objectives, they provide the foundation for developing a considered landscape recommendation.


Confidence begins with understanding

Every landscape presents a unique combination of opportunities, constraints and possibilities. Understanding these characteristics before important decisions are made provides a stronger foundation for successful landscape outcomes.

If you’re considering a landscape project and would like to begin with a Site Diagnostic, we’d welcome the opportunity to help you understand your landscape before important decisions are made, giving you the clarity and confidence to move forward.
