# Site Feasibility Study Checklist: 12 Things to Assess Before Your Design Brief

> A practical 12-point checklist covering planning, physical, environmental, access, and viability factors that should be tested before briefing design work.

## Quick Answer

Before writing the design brief, test 12 basics: planning context, overlays, flood risk, heritage and ecology, topography, access, solar orientation, neighbouring conditions, utilities assumptions, buildable area, transport performance, and exportable evidence. A feasibility study is useful only when it tells the team whether the proposed brief is realistic, weak, or needs to change before concept design starts.

## Introduction

The best feasibility studies are not verbose. They are decisive.

They tell the architect whether the brief still makes sense after the site is read properly. That matters because clients often arrive with a programme, a unit count, or an ambition level that sounds plausible until the site conditions are tested against it.

## Which checks can invalidate the brief fastest?

These are the first four:

1. **Planning status and allocation**
2. **Flood and environmental risk**
3. **Heritage and ecology triggers**
4. **Access and servicing reality**

If any of those four are materially worse than expected, the rest of the brief usually needs rethinking anyway.

## What 12 checks belong in every early feasibility review?

Use this as the base checklist:

1. planning designation and policy context
2. overlays and special review triggers
3. flood and drainage risk
4. heritage, ecology, and biodiversity constraints
5. topography and likely retaining implications
6. site access and servicing geometry
7. solar orientation and overshadowing risk
8. neighbouring buildings and interface sensitivity
9. transport and walkability performance
10. utilities or infrastructure assumptions
11. likely buildable area after constraints
12. whether the output is strong enough to brief the design team

That last item matters more than teams think. A feasibility study that cannot be shared and reused becomes another dead document.

## How should architects turn the checklist into a go or no-go tool?

Each item should end with one of three outcomes:

- supportive
- manageable with change
- material risk

That forces the architect to stop describing the site and start judging it. A conservation setting issue may be manageable with massing change. A flood-access failure may be a material risk. A weak station route may still be supportive if the scheme does not depend on low parking.

## What should the feasibility output look like?

A good output is short:

- one-page summary of opportunities and risks
- mapped constraints and movement layers
- note of what needs specialist verification next
- exportable material the design team can use immediately

## From Practice

On a residential-led site in Sheffield, the client arrived wanting 85 apartments because a nearby plot had recently achieved a similar number. The feasibility checklist stripped that assumption down very quickly. The buildable area shrank once the access geometry and level change were drawn properly, the western edge proved sensitive because of neighbouring privacy, and the strongest solar orientation did not support the deepest block the client had in mind. By the end of the review, the honest brief was closer to 65 units. That felt uncomfortable for five minutes and useful for the next six months.

## Frequently Asked Questions

**What is the purpose of a site feasibility study?**

To test whether the proposed brief still makes sense once the planning, physical, environmental, and movement realities of the site are known.

**What should be checked before writing the design brief?**

Planning context, constraints, flood, access, topography, solar, neighbouring conditions, transport, utilities assumptions, and likely buildable area.

**How detailed should feasibility be before concept design?**

Detailed enough to expose the main risks and opportunities, but not so detailed that the team mistakes early intelligence for final consultant sign-off.

**What is the biggest mistake in feasibility studies?**

Describing the site without judging what the findings mean for the actual brief.

**What makes a feasibility study useful to the wider team?**

A concise summary, clear mapped evidence, and outputs that can move directly into the next design stage.

## Conclusion

A site feasibility study should not just confirm that the team has looked at the site. It should reveal whether the current brief still deserves to survive. That is the point of the exercise.

If you want those twelve checks assembled into one faster and more reusable workflow, Atlasly is built for that pre-brief stage.
