A Guide to Planning House Extensions in Cambridgeshire

Before any drawings are made or forms are filled in, we come to you. A free, no-obligation home visit allows us to understand your space, listen to your ideas, and discuss what you want to achieve. It’s a chance for us to walk through the property together, brainstorm possibilities, and for you to ask us anything. This personal approach helps us tailor a design brief that truly reflects your family’s needs, which is a world away from the impersonal service of larger, national firms.

One of the first questions to answer is which planning route your project will need to take. The path depends on the scale, location, and design of your proposed extension.

• Permitted Development (PD): These rights allow you to make certain changes to your property without needing to apply for full planning permission. They are a great way to build modest extensions more quickly, but they come with strict limitations on size, height, and materials. We can advise if your vision fits within PD rules.
• Full Planning Permission: For larger or more complex projects that fall outside of Permitted Development, a formal planning application is required. This involves submitting detailed drawings and supporting documents to your local council for their assessment and approval. This is the most common route for significant house extensions.

To reduce stress and give you clarity, we manage the entire process on your behalf. Here’s how we turn your initial idea into an approved project.

1. Initial Sketches & Brief Refinement

Following our home visit and a full site survey, we create the first concept sketches. These visualisations bring your brief to life, showing you what your new extension could look like. We work with you to refine these ideas until you are completely happy with the proposed design.

2. Technical Drawings

Once the concept is agreed, we develop the sketches into a set of precise technical drawings. These are the detailed plans and elevations that your local council needs to see. They show the exact dimensions, materials, and appearance of the proposed work, forming the core of your planning application.

3. Submitting the Formal Planning Application

With the drawings complete, we compile and submit the formal planning application on your behalf through the government's Planning Portal. We handle all the administration and act as the agent for your application, meaning the council communicates directly with us. This saves you from having to manage complex correspondence and technical queries.

4. Awaiting the Council's Decision

Once submitted, the council typically aims to make a decision within 8 weeks. However, it's important to be aware of potential bottlenecks. We've seen significant delays recently in some districts like Huntingdonshire and East Cambridgeshire. We keep you informed throughout this waiting period and proactively manage any queries from the planning officer in charge of your case.

Having worked across the region for over a decade, we have a deep understanding of the different planning departments. Each council has its own priorities and policies, particularly concerning 'Designated Areas' or conservation zones. Whether you're dealing with the specific constraints in Huntingdonshire, the unique character of villages in South Cambs, or policies in East Cambs, our local experience is a key factor in our track record of success. We've secured approvals for family homes in St Neots, Huntingdon, and many surrounding villages, often where others have struggled.

Planning a home extension doesn't have to be a source of stress. With the right partner, it can be a creative and rewarding process that adds lasting value to your home and your family's quality of life. We provide a clear, supportive path from start to finish, ensuring your project is in safe, expert hands.
