FAQs

Can you guarantee my project will get planning approval?

No planning advisor can guarantee approval as final decisions rest with your local planning authority. However, we’ll assess risks and give you an honest view of your project’s prospects.

What can you cover in 30 minutes?

We’ll review your project, identify the likely planning route, highlight key risks, and give you clear next steps. It’s a focused session designed to give you clarity quickly.

What should I prepare for the call?

Have your property address ready, a basic description of your project, and any existing drawings or photos if available. We’ll guide you through the rest during our conversation.

Is it a phone or video call?

Your choice! We can do either phone or video call via Google Teams. Many clients prefer video calls as we can screen-share any relevant planning maps and documents.

What happens after the call if I want to move forward?

If you’re ready, we’ll explain the next step and (if you want) connect you to the Resi design/planning delivery team to scope drawings, surveys, and managing the planning application.

More questions?

We fortunately had our permitted development approved but the household planning permission faced a couple of challenges with the neighbours before getting approved. Danielle was an absolute superstar in supporting us through the journey.
