What is a Planning Feasibility Study?

A Planning Feasibility Study, also called a Site Appraisal, is a professional desktop review carried out by a Chartered Town Planner.

Before you pay for architects, planning drawings or surveys, we assess whether your idea is actually achievable under current planning policy.

We research your specific site, your council's Local Plan, national planning policy, relevant planning history and site-specific constraints, then give you a plain-English verdict you can act on.

Think of it as a planning MOT for your site — identifying problems and opportunities before they cost you money.

A Site-Specific Planning Review

What We Assess Before Recommending a Planning Route

A feasibility appraisal should do more than reproduce planning policies. It should explain how the planning framework applies to the site, which matters are likely to influence a future decision and whether the development concept is proportionate to the opportunities and constraints.

The scope is tailored to the proposal. The matters below are considered where relevant, using the information available through a desktop review. Where a specialist technical assessment is needed, we identify that as part of the recommended next steps.

01

Planning Policy and the Principle of Development

We review the adopted development plan, relevant national policy, neighbourhood planning policies and material emerging Local Plan provisions. This helps establish whether the proposed use or development has a policy basis and where exceptions or planning balance arguments may be required.

02

Planning History and Relevant Decisions

Previous permissions, refusals, enforcement history and appeal decisions can reveal how the authority has approached the site. We also consider relevant nearby decisions where they provide useful context, while recognising that each proposal must be assessed on its own facts.

03

Settlement Boundaries, Countryside and Green Belt

The location of a site can be central to the planning strategy. We assess whether it lies within a defined settlement, open countryside, Green Belt, safeguarded land or another policy designation and explain how this affects the principle and likely route forward.

04

Character, Design and Neighbouring Amenity

We consider the surrounding pattern of development, local character, scale, density and likely relationships with neighbouring property. This can influence the design brief, including height, layout, separation distances, outlook, privacy and potential overbearing effects.

05

Access, Highways and Sustainable Location

At a strategic level, we review access arrangements, visibility, parking, servicing, likely vehicle movements and connections to local services and sustainable transport. We identify where highway drawings, transport evidence or specialist advice may be needed.

06

Heritage and Townscape

We identify listed buildings, Conservation Areas, scheduled monuments and other heritage considerations that may affect the principle, scale or design of development. The review also considers whether a Heritage Statement or specialist assessment is likely to be required.

07

Flood Risk, Drainage and Environmental Constraints

We review readily available flood mapping, drainage information and environmental designations. This helps identify possible sequential issues, surface water constraints and the need for more detailed technical evidence before an application is prepared.

08

Ecology, Trees and Biodiversity Net Gain

The appraisal can flag protected habitats, ecological designations, important trees and the potential relevance of biodiversity net gain. We do not replace an ecologist or arboricultural consultant, but we identify where their evidence may affect feasibility, layout or cost.

09

Application Strategy and Supporting Information

We recommend the most proportionate planning route and identify likely supporting documents. This may include full planning permission, outline permission, prior approval, a Lawful Development Certificate, pre-application engagement or longer-term Local Plan promotion.

10

Overall Prospects and Actionable Next Steps

The conclusion brings the assessment together in plain English. It explains the strongest opportunities, the principal risks, whether the proposal should proceed in its current form and what should happen before further money is committed.

The objective is commercially minded advice, not a policy dump.

Our report is designed to help you decide whether to proceed, revise the concept, seek further evidence, approach the council or avoid unnecessary expenditure on a proposal with significant unresolved planning risk.

Why Assess the Site First?

Why Undertake a Feasibility Study Before Commissioning Full Drawings?

Architectural drawings, ecology surveys, transport work, drainage assessments and other technical reports can represent a significant investment. Some of that work may ultimately be required, but it is often sensible to establish the broad planning position before commissioning the full application package.

Early planning research can reveal issues that materially affect the design brief. A site that initially appears capable of accommodating several homes may be constrained by an important landscape gap, heritage setting, access limitation, flood zone, protected habitat or local policy requirement. Equally, planning history or a relevant appeal decision may identify a more positive route than first assumed.

A planning feasibility study can therefore help architects and clients start with a more informed brief. Rather than preparing a design and then trying to defend it against planning constraints, the design can respond to policy, context and likely decision-making issues from the outset.

A feasibility study can help you:

  • Understand whether development is acceptable in principle
  • Identify the strongest and weakest aspects of an opportunity
  • Set a more realistic development brief
  • Decide whether council pre-application advice would add value
  • Anticipate likely surveys and supporting reports
  • Assess whether an application is worth pursuing
  • Inform land purchase, promotion or option discussions
  • Reduce the risk of designing around a flawed assumption
A Strategic Starting Point

What Does a Planning Feasibility Study Tell You?

The output should provide a clear professional view rather than a list of policies with no conclusion. Cedar Planning explains what the planning framework means for the specific site and proposal, where the important risks lie and what should happen next.

The advice may conclude that the proposal has a reasonable basis and can move towards design and an application. It may recommend reducing the scale, changing the use, repositioning development, retaining important site features or gathering more evidence before committing to a formal submission.

For more complex or sensitive sites, the recommendation may be to seek formal pre-application advice from the local planning authority. The feasibility study can help define the questions to ask and ensure that a pre-application submission focuses on the issues that genuinely require an officer view.

Where a site has longer-term potential but is not currently supported by policy, the appropriate route may involve a Local Plan representation, call for sites submission or strategic land promotion rather than an immediate planning application.

Who Uses Feasibility Advice?

Planning Appraisals for Homeowners, Landowners, Developers and Architects

Feasibility studies can be proportionate to a wide range of projects. For a homeowner, the question may be whether a new dwelling, annexe, replacement home or substantial extension is realistic. For a landowner or developer, the assessment may consider residential capacity, redevelopment, infill, rural development or a longer-term land promotion strategy.

Architects and designers also use early planning input to test a client's brief before significant design work begins. Planning and design are most effective when they develop together: the appraisal identifies the planning parameters, while the architect tests how an attractive and functional scheme can respond to them.

Commercial feasibility work can consider changes of use, mixed-use development, leisure proposals, employment premises and the planning implications of operational requirements. Heritage and rural sites may require additional care because the principle of development and the evidence required can depend heavily on context.

Our Process

From Site Information to a Clear Planning Strategy

The process is designed to provide useful planning direction without requiring the full level of information normally prepared for a planning application.

01

Tell Us About the Site

Provide the address or location plan, the development being considered and any existing drawings or relevant background information.

02

Desktop Planning Review

We assess policy, planning history, mapped constraints, the surrounding context and relevant decisions where they assist the appraisal.

03

Written Feasibility Report

You receive a site-specific appraisal explaining opportunities, risks, likely requirements and our professional view on the route forward.

04

Decide the Next Step

The recommendation may be to proceed, refine the concept, seek council advice, obtain targeted evidence or avoid further expenditure.

Choosing the Right Early-Stage Advice

Planning Feasibility Study or Council Pre-Application Advice?

The two services can complement one another, but they are not the same. A private feasibility appraisal can help you decide whether, when and how to approach the council.

Cedar Planning

Independent Planning Feasibility Study

Confidential, client-focused advice that can be obtained at a very early stage, before a detailed design package has been prepared.

  • Independent professional advice acting for you
  • Helps shape the development brief
  • Can compare alternative planning routes
  • Identifies whether council pre-application advice is worthwhile
  • Provides a clear view on risk before substantial expenditure
Local Planning Authority

Council Pre-Application Advice

An early officer view from the local planning authority. The fee, information requirements, response time and level of detail vary between councils and according to the scale of development.

  • Provides an indication of the council's likely position
  • May identify validation and technical requirements
  • Can test a developed concept with planning officers
  • Is normally charged separately by the council
  • Does not bind the council or guarantee a future decision
Clear Recommendations

What Might the Feasibility Study Recommend?

A useful appraisal should not force every opportunity towards the same outcome. The recommendation is tailored to the planning position and the client's objectives.

Proceed Towards an Application

The principle appears supportable and the next step is to develop the design, commission the necessary reports and prepare an application.

Refine the Proposal

The opportunity has potential, but the scale, use, layout, access or design brief should change before further work is commissioned.

Seek Further Evidence or Pre-App Advice

A key uncertainty requires specialist input, council feedback or targeted evidence before the route forward can be confirmed.

Do Not Proceed in the Current Form

The policy conflict or planning risk is sufficiently significant that further expenditure on the current proposal may not be justified.

Planning Feasibility FAQs

Common Questions About Planning Site Appraisals

These answers provide general guidance. The scope and reliability of a feasibility assessment depend on the site, proposal and information available.

What is included in a planning feasibility study?

The exact scope is agreed before work begins. A desktop appraisal commonly reviews the development plan, national policy, planning history, relevant site designations, known constraints, surrounding development context and the likely planning route.

The written advice identifies the principal opportunities, risks and likely application requirements before providing a clear recommendation on the next step. Specialist technical assessments, measured surveys, architectural design and detailed financial viability work are separate unless expressly included.

Is a planning feasibility study the same as a site appraisal?

The terms are often used interchangeably. Both usually describe an early review of a site's planning potential, constraints and likely route towards development. The important point is the agreed scope and whether the advice provides a site-specific conclusion rather than only reproducing policy information.

Can a feasibility study guarantee planning permission?

No. A feasibility study is a professional planning opinion based on the information available at the time. A future application will be determined on the submitted scheme, consultation responses, planning policy and other material considerations.

Its value is in identifying risk early, improving the strategy and helping you make a more informed decision before committing to the full cost of an application.

Do I need architectural drawings before requesting a feasibility study?

Not always. For many initial appraisals, a site address or location plan and a clear description of the development being considered are enough to begin. Existing sketches or concept drawings are useful where they are already available.

Where prospects depend heavily on a particular layout, height, access arrangement or relationship with neighbouring property, more design information may be needed before a reliable view can be given.

Does the feasibility study include a site visit?

The standard feasibility service is normally a desktop planning appraisal. A site visit can be quoted separately where the scale, visibility, physical characteristics or complexity of the site mean that an inspection would materially improve the advice.

How long does a planning feasibility study take?

Timescales depend on the size and complexity of the site, the amount of planning history and the scope agreed. We provide an expected delivery date with the quotation. Straightforward desktop appraisals can usually be completed more quickly than strategic or heavily constrained site reviews.

How much does a planning feasibility study cost?

The professional fee depends on the site, proposal, number of development options and depth of research required. Cedar Planning provides a fixed-fee quotation before work begins.

A small residential appraisal will generally require less work than an assessment involving a large site, extensive planning history, emerging Local Plan issues or multiple development scenarios.

Will the study tell me how many homes can fit on the site?

It may provide an initial planning view on a realistic range or development principles, but precise capacity often requires architectural testing. Access, layout, landscape, trees, drainage, heritage, ecology, amenity, open space and local character may all influence the number and form of homes that can be accommodated.

Can a feasibility study help before buying land or property?

Yes. Early planning due diligence can identify policy constraints, planning history and risks that may affect development potential or the assumptions supporting a purchase. This can inform negotiations, option agreements, conditional contracts or a decision not to proceed.

A planning appraisal is not a valuation, legal title review, environmental due diligence report or guarantee of development value.

What happens after the feasibility study?

The next step depends on the recommendation. You may proceed to design and a planning application , seek council pre-application advice, obtain specialist survey work or revise the development brief.

Cedar Planning can continue to support the project through strategy, coordination with the design team, preparation of a Planning Statement and application management where required.
