What is a Planning Appraisal in Architecture?

Before jumping into any renovation or extension project, it’s important to know whether the project is even possible. That’s where a planning appraisal will take effect. This early-stage assessment helps you understand the development potential of your site, giving you clarity before you commit time or money to plans that may not go ahead.

What does a planning appraisal include?

A planning appraisal is a professional review that looks at what you can realistically build on your site. It involves assessing local planning policies, physical site constraints, and the broader context of your project.

Your architectural designer will research the planning history of the property and surrounding area, identify any planning restrictions, and flag any major hurdles – such as conservation areas, flood risks, or green belt designation – that could affect your plans.

While you might have clear ideas about what you’d like to build, a planning appraisal will inform you what local authorities are likely to approve. It’s a critical step in turning a concept into a compliant, buildable project.

Why this early step can save time and money

Without a planning appraisal, you risk spending money on design work that might not meet local planning rules. Worse still, you could end up submitting an application that has little chance of success.

A planning appraisal helps avoid that. It gives you a realistic view of what’s possible so you can move forward with confidence. If the outcome is favourable, your architectural designer can then guide the project through the next steps: design development, planning submission, and technical drawings.

If the outcome suggests challenges, you’ll be in a stronger position to rethink your approach or adjust your expectations before making a financial commitment.

Who should consider a planning appraisal?

This type of assessment is ideal for anyone in the early stages of a new build, renovation or extension project. If you’ve got a large garden and want to know if you can add another house, or you’re considering a side extension but unsure about space or permissions, a planning appraisal is the right place to start.

It’s also a key step for anyone dealing with unusual plots, tricky boundaries, or tight planning restrictions. Instead of guessing or relying on outdated advice, you’ll have clear, expert insights.
