Preliminary ecology appraisal
Ecological review forms part of the planning evidence, allowing relevant constraints and mitigation to be considered alongside the emerging design.

A planning-led appraisal for a potential dwelling within an existing residential curtilage, coordinating site context with specialist evidence before design and submission.
- Opportunity
- Single residential dwelling
- Evidence
- Site, trees and ecology
- Purpose
- Early planning-risk decisions
THE DECISION FRAMEWORK
Four questions before design begins.
- 01
Can the site credibly accommodate another dwelling?
- 02
Which trees, root protection areas and access conditions constrain it?
- 03
What protection, mitigation and supervised methods are required?
- 04
Which specialist evidence must support a planning submission?
EVIDENCE BASE
Due diligence made visible.
The appraisal combines the site plan with specialist arboricultural and ecological information, so constraints influence the proposal early rather than becoming late surprises.
Site context and access
The block plan establishes the development area, neighbouring relationships, access and the wider residential setting.
Arboricultural impact
The specialist assessment identifies tree constraints and the mitigation needed to make a credible planning proposition.
Tree protection strategy
Protective fencing, ground protection and controlled excavation methods translate assessment findings into an achievable site strategy.
COMMERCIAL FEASIBILITY
Planning potential is only half the appraisal.
Once a credible planning route is established, the assessment can be extended into an acquisition brief with measured development areas, build cost, professional fees, finance, sales value and residual land value.
- Development area and accommodation schedule
- Construction and professional-cost allowances
- Gross development value and sensitivity testing
- Residual value, margin and key acquisition risks
THE VALUE OF EARLY APPRAISAL
Evidence first. Better decisions next.
Bringing site geometry, tree constraints, protection measures and ecology into the conversation early creates a more defensible planning strategy and reduces avoidable design, purchase and construction risk.
