HOW TO INVESTIGATE A PARCEL OF LAND
Investigating land means answering six questions in order: where exactly is it, what has been proposed here before, what constrains it, how is it reached, what has physically changed, and what do we still not know. Recording the answers — including the unknowns — is what makes the investigation reusable rather than disposable.
UPDATED 2026-09-01 · WRITTEN FOR: ANYONE WHO HAS A SPECIFIC PARCEL AND NEEDS A DEFENSIBLE ASSESSMENT.
1. FIX THE LOCATION AND EXTENT
Ambiguity about extent invalidates everything downstream. Establish the boundary you are actually assessing, note where it is uncertain, and keep that boundary attached to the record so later evidence is anchored to the same parcel.
2. READ THE PLANNING HISTORY PROPERLY
Look beyond the headline decision. Refusal reasons, officer reports, conditions, withdrawals and appeal outcomes describe how the authority has reasoned about this land. Extend the search to immediately adjacent parcels — precedent nearby often matters more than history on the site itself.
3. ESTABLISH THE CONSTRAINTS
- Flood risk designations and any surface-water indications.
- Heritage, landscape and ecological designations.
- Trees, protected features and known contamination history.
- Utilities, easements and rights of way.
- Local plan status: allocation, settlement boundary position, policy designations.
4. UNDERSTAND ACCESS
Access is the constraint most often discovered late and most likely to end a deal. Establish the highway relationship, frontage, visibility, and whether any third-party land is required. Where the answer is uncertain, record it as an unknown with a named next step.
5. COMPARE THE SITE OVER TIME
Imagery from different dates shows clearance, structures, tracks, storage, vegetation change and works in progress. This is observation, not interpretation: it tells you something happened and roughly when, and prompts the question of what and why.
6. WRITE DOWN THE UNKNOWNS
An investigation that lists ten unknowns with owners and next steps is more valuable than one that presents a clean but unverified conclusion. Unknowns are the work plan.
- Public planning records vary in completeness and digitisation, particularly for older decisions.
- Constraint datasets are indicative at a national scale and do not replace site-specific assessment.
- Imagery shows change, not cause, permission or ownership.
- None of this substitutes for legal title investigation, survey or professional planning advice.
- One persistent record per site holding evidence, imagery over time, questions and conclusions.
- Evidence provenance on every item so a reviewer can see where a statement came from.
- A change timeline showing what moved between visits.
- Ask AXARA to interrogate the assembled record and cite the evidence behind each answer.
- Explicit unknowns rather than silent gaps.
What is land investigation?
The structured gathering of evidence about a specific parcel — location, planning history, constraints, access and physical change — to support a decision about acquisition or development.
How is investigation different from due diligence?
Investigation is the earlier, cheaper, evidence-gathering stage that decides whether formal due diligence is worth commissioning.
What is the most commonly missed issue?
Access. Sites frequently fail because a required visibility splay, frontage or third-party strip is discovered after significant spend.
How far back should planning history go?
As far as the records allow. Older refusals and lapsed consents often explain current officer attitudes, though digitisation of historic records is inconsistent.
Should I keep records of sites I do not pursue?
Yes. Most of the cost is in the reasoning, and circumstances change. A rejected site with a recorded rationale is a cheap future opportunity.
Can AXARA tell me if planning will be granted?
No. It assembles and remembers the evidence around a site. Planning outcomes are determined by the authority on the facts of an application.
