We agree what the appraisal must establish, the level of certainty required and the information already available.

Feasibility and Development Advice
A focused feasibility study tests what a property or site can realistically support before substantial design fees, consultant costs or acquisition commitments are made. The output identifies opportunity, constraints, approval routes and the evidence needed for the next decision.
Suitable for
Projects we can support.
- Sites or buildings being considered before purchase
- Infill, backland and small housing sites
- Commercial and agricultural conversions
- Replacement dwellings and one-off homes
- Alternative options after a refusal
Our process
A structured route through the project.
Evidence and constraints
Planning history, policy, designations, access, neighbouring relationships, landscape, flood and infrastructure issues are reviewed proportionately.
Capacity options
Sketch layouts test realistic scale, unit numbers, access, parking, amenity and the main design trade-offs.
Recommendation
The findings set out the preferred route, principal risks, consultant requirements and whether further investment is justified.
Typical deliverables
What the appointment may include.
The final scope is confirmed in a written fee proposal tailored to the property and approval route.

Site-constraint summary
Sketch capacity layouts
Approval-route comparison
Risk and consultant schedule
Clear next-step recommendation
RIBA-aligned scope
Clear stages and responsibilities.
The appointment is aligned to the RIBA Plan of Work stages that are proportionate to a residential project.
Stage 0: strategic definition and opportunity review
Stage 1: preparation, brief and feasibility
Stage 2: concept options where included
Indicative timescales.
- Focused desktop review: usually 1–2 weeks
- Measured or site-based capacity study: commonly 2–4 weeks
- Larger multi-option appraisals: programme agreed after the brief and information are reviewed
Proportionate fixed scopes.
Feasibility is normally a defined fixed-fee first stage. Where the project proceeds into an agreed planning appointment, the later fee proposal can recognise relevant work already completed rather than duplicating it.

Frequently asked questions
Common questions about this service.
Can you assess a property before I buy it?
Yes. The scope can be tailored to the purchase decision, from a focused desktop review to a site visit and sketch capacity study.
Will a feasibility study guarantee planning permission?
No. It provides an evidence-led view of opportunity and risk, but only the local planning authority or an appeal decision can determine an application.
Do you calculate the land value or development profit?
No. We assess architectural and planning capacity. Formal valuation and financial appraisal should be undertaken by appropriately qualified advisers using the tested development assumptions.
Can the feasibility work be used for a planning application?
Often, yes. Useful survey, research and design work can be carried forward, but formal planning drawings and supporting documents require a separate agreed scope.
