Understand What Your Site Can Really Deliver

Before any spade goes in the ground, before any architect's drawing gets sent to Cornwall Council, before you commit to a builder, you need to know one thing: is this project actually possible? A proper feasibility study answers that question with clarity, evidence, and practical guidance you can act on.

At Archico, we offer detailed feasibility studies for clients across Cornwall, helping you assess a site's potential, navigate planning constraints, and evaluate the real-world viability of your idea. As a CIAT Chartered Practice based in Callington, we bring extensive experience of Cornwall's planning landscape to every project, from coastal new builds to barn conversions and listed buildings.

Whether you're a homeowner thinking about an extension, a landowner exploring development potential, or a contractor weighing up a site purchase, a feasibility study saves time, money, and disappointment further down the line.

What Is a Feasibility Study?

A feasibility study is a structured assessment of a site or proposal, designed to evaluate whether your project is achievable, viable, and worth pursuing. It's a critical first step that helps you make informed decisions before committing significant funds to design, planning, or construction.

A typical feasibility study covers:

  • Site analysis including access, topography, services, and constraints

  • Planning policy review against the Cornwall Council's local plan

  • Heritage and conservation considerations for listed buildings or designated areas

  • Environmental and landscape factors, including Areas of Outstanding Natural Beauty

  • Initial design options showing what could reasonably be built

  • Cost and viability indications to guide your budget thinking

  • Risk identification flagging potential challenges early

  • Recommendations on next steps and the best route forward

The output is a clear, structured report you can use to make decisions, support funding applications, share with stakeholders, or guide your design team into the next stage.

When You Should Commission a Feasibility Study

Feasibility studies aren't just for major developments. They're equally valuable for homeowners, landowners, and contractors at every stage.

A feasibility study makes sense if:

  • You're considering purchasing a site or property with development potential

  • You're a landowner exploring options for unused buildings, paddocks, or fields

  • You're thinking about a large extension or conversion to your existing home

  • Your site sits within an AONB, conservation area, or near listed buildings

  • You're looking at a Class Q barn conversion under permitted development rights

  • You're considering multiple self-build plots or a small residential development

  • You've had a planning application refused and want to understand the options

  • You need evidence to support funding applications or grant submissions

The earlier you commission a feasibility study, the more time and money you'll save. Project costs only go up as you move through the design stages, so getting clarity early is always a smart move.

Why Feasibility Studies Matter in Cornwall

Building in Cornwall has its challenges, coastal AONBs, conservation areas, listed buildings, agricultural land restrictions and protected landscapes can all influence what is possible on a site. A plot that appears ideal during an initial viewing may have planning constraints that significantly impact the viability of a project.

Across Cornwall, development proposals often need to consider factors such as Areas of Outstanding Natural Beauty, conservation area restrictions, listed building requirements, coastal exposure, flood risk, heritage assets and protected landscapes. Additional considerations can include Sites of Special Scientific Interest (SSSIs), local planning policies relating to principal residences and second homes, Class Q permitted development rules for agricultural conversions, and local plan allocations that determine whether land is suitable for development.

Without a clear understanding of these constraints from the outset, projects can quickly become more complex, costly and time-consuming than expected. A professional feasibility study helps identify potential challenges early, providing a realistic assessment of what can be achieved before significant time and money are invested.

What We Cover in a Feasibility Study

Every site is different. Our feasibility studies are tailored to the specific brief, but most include the following structured analysis.

Where appropriate, we also coordinate with planning consultants, structural engineers, ecologists, and heritage specialists to build a complete picture of the site's potential.

How a Feasibility Study Supports Your Planning Application

Many of our clients use a feasibility study as the foundation for a successful planning application. By identifying site constraints and opportunities at an early stage, we can help shape proposals that align with Cornwall Council's planning policies and improve the likelihood of approval. A feasibility study can highlight sensitive planning issues before designs are developed, identify supporting documents that may be required such as heritage statements or ecological surveys, and provide valuable information for pre-application discussions with planning officers.

It also demonstrates a considered and well-informed approach to development, helping to reduce the risk of delays, refusals or costly redesigns later in the process. We work closely with Cornwall Council and have extensive experience of how local planning teams assess different types of proposals, allowing us to structure each feasibility report around the factors most likely to influence a successful outcome.

Frequently Asked Questions//

  • Most feasibility studies in Cornwall are completed within 3 to 6 weeks. Larger sites, complex constraints, or projects requiring input from specialists may take longer. We'll confirm timescales upfront so you can plan future stages with confidence.

  • It's not legally required, but it's strongly recommended. A feasibility study gives you the evidence and understanding to shape Cornish planning applications that have a real chance of obtaining planning permission, helping you avoid wasted time and money.

  • Yes. We assist clients with sensitive sites, including AONBs, conservation areas, and properties near listed buildings. Our studies consider important factors like heritage, landscape, sustainability, and environmental factors as standard, helping create proposals that respect their setting.

  • Yes. Class Q has specific technical requirements around the building's condition, agricultural use, and structural integrity. For example, a feasibility study confirms whether the conversion qualifies and what additional work is needed to secure prior approval.

  • Our feasibility work focuses primarily on planning viability, but we flag key building control and technical requirements that could influence design and cost. This sets a clear foundation for the next stage when full compliance is addressed.

  • Yes. Subject to your needs, we can support projects from feasibility through full design, planning, building control, and construction. We've built strong partnerships with local consultants and contractors to deliver projects with consistent quality throughout.
